Abstract

PURPOSE:To enhance output of motor by arranging such that the flux passes only through one side of the bottom of an armature coil and does not pass through three other sides. CONSTITUTION:An armature coil 5a is wound around a magnetic body 5. N pole face of a magnet rotor 4a opposes through an air gap to the protrusion of the magnetic body 5. Upon power supply to the armature coil 5a, flux flows in the directions of arrows 23a, 23b, where the flux 23a is dense because the magnetic path is closed whereas the flux 23b is sparse. Path of N pole of the magnet rotor 4a passes through the magnetic body 5 and closes at S pole, as shown by arrows 24a, 24b. Flux shown by arrows 23a, 23b are added on the right at the lower part of the magnetic body 5 and increased, whereas subtracted and decreased on the left side. Consequently, the magnet rotor 4a produces driving torque in the direction of an arrow L. At this time, flux shown by the arrow 23a is added/subtracted to/from the fluxes shown by arrows 24a, 24b to produce a counter torque which can be neglected because the flux shown by the arrow 23b is low.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is used as a generator (tacho generator) which is proportional to rotational speed and has no voltage ripple and noise, or as a DC motor without output torque ripple.

[Conventional technology]

Although many techniques with a configuration similar to the device of the present invention have been proposed, many of them have theoretical errors (and there are no examples of practical use. For example, There is a technique described.

[Problems to be solved by the present invention] First problem Multi-phase generators include ripple voltage in their DC output, so it is impossible to obtain a DC output proportional to the rotation speed. When smoothing with a capacitor, a time lag occurs, making it impossible to obtain a voltage that accurately follows changes in rotational speed, which is a disadvantage when used as a tacho generator.

Second Problem: Since the number of phases is small in the case of a multi-phase DC motor, especially a brushless DC motor, there is a problem in that it generates torque crisis, electromagnetic noise, and mechanical vibration.

No. 30 In the case of brushless generators and DC motors, the rectifier is a semiconductor circuit, which is expensive, and there are problems in that electromagnetic noise is generated during phase switching. It also has the disadvantage of generating mechanical vibrations.

Problem No. 3 In the case of a DC motor, when a brushless motor is used, the number of phases is /~3, so it takes time for the magnetic energy of the armature coil to disappear and accumulate during phase switching.

Therefore, if the speed is set to high, the generation of counter torque increases, there is a limit to the increase in rotational speed, and there is a problem that the efficiency deteriorates. When the speed is high (700,000 revolutions per minute or more), there are problems in that iron loss increases, heat generation increases, and efficiency deteriorates.

Problem S: There is iron loss due to disappearance and accumulation of magnetic energy in the armature coil, which may cause a problem of deterioration of efficiency.

As mentioned above, high speeds pose a major problem.

[Effect]

The first to fifth problems described above are common drawbacks of well-known l-phase, co-phase, and three-phase electric motors. This may be a problem due to the concept of phase. 3.2. What can be deduced from the concept of /, 0 is that the above-mentioned problems can be eliminated by escaping from the concept of phases and creating an O-phase, that is, a phaseless electric motor.

The device of the present invention solves the first to Sth problems by configuring a phaseless electric motor.

Next, we will explain its operation. Since the armature coil is always energized in the / direction at the set value, there is no phase switching (and there is no large inflow or outflow of magnetic energy in the armature coil). When used as a generator, the first problem is solved because it has the effect of providing a voltage output that is accurately proportional to the rotational speed and has good compatibility.

When used as an electric motor, for the same reason, there is no torque ripple (and electrical or mechanical vibrations are eliminated), so the first problem is solved.

Since there is no need for a rectifier for phase switching, there is no need for a semiconductor control circuit including a Hall element for that purpose, and it is possible to obtain a motor that obtains the total power of the rotor simply by energizing the armature coil from a DC power source.

The above-mentioned situation is the same in the case of a generator.

Therefore, the third problem is solved.

Since there is no increase or decrease in the magnetic energy stored in the armature coil, there is no generation of counter torque due to the release of magnetic energy when electricity is cut off, unlike in the case of ordinary electric motors. Therefore,
Since it is possible to obtain a high-speed electric motor (more than 100,000 revolutions per minute), problem 3 can be solved.

Although the armature coil has a magnetic core, the amount of magnetic flux passing through it does not change, so there is no iron loss (and a highly efficient motor can be obtained).

Therefore, there is an effect of solving the fifth problem.

The device of the present invention is characterized in that it can provide a particularly large output motor or power generation mode. By energizing the armature coil that contributes to the output. The above-mentioned characteristics are achieved because the magnetic resistance of the magnetic flux path is small.

〔Example〕

The details of the apparatus of the present invention will be explained with respect to the embodiments shown in FIG. 1 and subsequent figures. Since the same symbols in the drawings indicate the same members, a redundant explanation thereof will be omitted.

FIG. 1(a) is an explanatory diagram of the rotor lla and armature coil 5a of the device of the present invention. . These parts are shown in Figure 2 (a
) are shown with the same symbol.

The rotor (a) has a disk shape, and the magnet (a) is omitted and not shown. A rotating shaft l is fixed at the center.

The outer periphery of the rotor +a is magnetized to the north pole.

The symbol 5a indicated by a dotted line is an armature coil, which is wound in a rectangular shape. Arrow? a, '7b, and '7c indicate lines of magnetic force.

FIG. 1(b) shows the armature coil 5a, magnetic lines of force 7a, 7b,
? This is an enlarged view of c.

As shown in the figure, the lower and upper parts of the armature coil 5a are in the direction of the rotation axis of the rotor 4 (a), and both sides are perpendicular to the magnetic pole surface. The directions of the induced voltage induced in the armature coil 5a when it rotates in the A direction are indicated by arrows gh and gb.

The directions are ga and gd.

With respect to the voltage in the direction of arrow ga, all induced voltages generated on other sides are in the opposite direction.

Since the amount of magnetic flux penetrating the lower coil portion is equal to the amount of magnetic flux penetrating the coil portions on the other three sides, the induced voltage in the entire armature coil disappears.

When the armature coil 5a is energized in the direction opposite to the arrow ga, the torque that drives the magnet rotor t in the direction of the arrow ga is also not generated for the same reason.

The device of the present invention is configured so that the magnetic flux penetrates only the bottom seven sides of the lower side of the armature coil 5a, and does not penetrate the coil portions on the other three sides, and is used as a generator or an electric motor. The details are explained next.

As will be described later in the embodiment, the magnetic flux generated by the armature coil JA includes magnetic flux that generates positive torque and anti-torque, so the magnetic flux that generates anti-torque is eliminated to generate only positive torque. This achieves the object of the present invention.

Next, the means described above with reference to FIG. 1(C) will be specifically explained.

In FIG. 1(C), the armature coil 5a is shown in FIG. 1(b).

The magnetic flux when the armature coil, ffa is energized is shown by arrow 2.
3a and 23b, the magnetic flux indicated by arrow 2.3a is significantly thicker because the magnetic path is closed (dotted line arrow 2).
．． The magnetic flux of 3b becomes significantly smaller.

The magnetic fluxes indicated by the arrow 23a and the arrow 21Ia are added and increased on the right side of the lower part of the magnetic body S, and are subtracted and decreased on the left side.

Therefore, the magnet rotor q generates a driving torque in the direction of the arrow. At this time, the magnetic flux of arrow u3b is
(It is added to and subtracted from the magnetic flux of arrows a, 24'b to generate a counter torque, but since the magnetic flux of arrow 23b is extremely small, it can be ignored and there is no problem.

The apparatus of the present invention achieves the object by the means shown in FIG. 1(C).

Next, the details will be explained.

The magnetic path is closed by /9a, the details of which will be described later.

The other half circumferential portions also have the same configuration.

In FIG. 3(a), the symbol /, ? The armature magnetic core shown in a has magnetic flux? Projections /+a, /4'b, . . . that project in the generatrix direction of the cylinder are provided from aa-mi.

,／・? The present invention can also be carried out by consecutively forming 7 b's.

The reason why the above-mentioned voids are necessary will be described later.

The section indicated by arrow /7a faces the north pole surface of the outer periphery of the rotor lIa in FIG. The section indicated by the arrow /'7c is the interval between the rotors IIa and 'xb.

Armature core? a, /,? b, . . . can be made by processing a mild steel material or sintering its powder.

It can also be made by sintering silicon steel powder.

Armature core made as shown in Figure 3(a)/? a
, /,? b, . . . are also inserted into the sides of the outer casing shown in FIG. 2(a) after the armature coils are installed.

In order to set the insertion position at a predetermined position, protrusions (ring-shaped) corresponding to the widths of the arrows /2a, /2b, ... are provided on the inner peripheral surface of the outer casing //, and the protrusions The armature core is inserted and fixed using the guide member.

For this purpose, the side plates 2a, 2b have protrusions --/.

- Is there one armature core/? a, /3b and their protrusions /4'a, /'i'b, . . . are configured to be pressed from the left and right.

As can be understood from the above explanation, the inner peripheral surface of the outer casing // and the rotor! The distance between a and the outer peripheral surface of 4b becomes the set air gap length, and the armature core /,? a, its protrusion /'Ia, /
The outer peripheral surfaces of llb, rotor Fa, and llb also face each other with the same gap length. Also, the armature coil! The inner sides of ra, 3b, ... face the outer rotating surface of rotor lla, and the protrusions /lIa, /! b

... is opposed to the outer rotating surface of rotor/Ib.

Therefore, the widths of the arrows /7a and /7b in FIG. 3(a) are 1 of the rotors +a and +b, respectively.

A cross-sectional view taken along the dotted line E in Figure 2(a) in the direction of the arrow, that is, a cross-sectional view taken along the dotted line J in Figure 3(a) in the direction of the arrow is shown in Figure 3(a). Explain. In Fig. 9(a), the armature core /, ? a, /,? b
The armature coils 5a, jb, .
It faces the north pole of the outer rotating surface of the rotor 4a.

The armatures on the other half-circumferences have the same configuration, and although not shown, armature coils je, 5f, . . . are attached thereto.

The details will be explained below using the armature coil 5a as an example.

In FIG. 9(b), the armature core /, ? A winding frame (core) made by plastic molding is fixed to the upper surface of the armature coil 5a, and the armature coil 5a is wound between the core n and the four parts on the lower surface.

The magnetic flux of the N pole of rotor ++a is indicated by arrows 211a and 211b.
.

As shown by 2'l, the armature core /, ? a, then the protrusion /4'a (shown in FIG. 3(a)) and the protrusion /11.a on the opposite side. passing through b, S of the outer rotating surface of rotor +b
The magnetic path is closed at the pole.

The magnetic flux due to energization of armature coil &a is shown by arrow a3a, arrow (dotted line), and 23b, but the magnetic resistance of the magnetic flux closed by arrow 23a is significantly smaller than that of the magnetic flux closed by arrow 231D. , substantially only the magnetic flux indicated by the arrow 3a.

Therefore, the magnetic flux density on the left side of the armature coil (arrow 2.7a
and arrow: This is the difference in the magnetic flux of L'lh. ) is the magnetic flux density on the right side (the sum of the magnetic fluxes of arrow 23eh and arrow u/lb).
becomes smaller compared to

Therefore, the rotor 4Za generates a driving force in the direction of the arrow and rotates.

Since the other armature coils have the same effect, a driving torque is generated in the rotor 4a, and the rotor 4a becomes a DC motor that drives a load via the rotating shaft l. The counter torque is generated by the armature core of the magnetic flux of arrow 23b and the magnetic flux of rotor lIa/? This is due to the upward leakage magnetic flux of a, but this is extremely small and poses no problem.

In order to satisfy the above conditions, the armature core /,? It is necessary to make the cross-sectional area of a and the protrusions /4'a and /4'b sufficiently large to prevent magnetic saturation. Also armature coil arrow 23
In order to increase the magnetic flux density of a, it is necessary to decrease the magnetic resistance. For this reason, it is necessary to reduce the gap between the outer peripheral surface of the rotor 9a and the protrusions on both sides of the armature coil. The fact that the rotor Ila is made of mild steel is one effective means for closing the magnetic path indicated by the arrow 23a and increasing the magnetic flux density.

When the rotor 9a faces the left and right protrusions of the armature coil &a, the magnetic flux density near the outer peripheral surface of the rotor &a increases, causing iron loss during rotation. rotor lla,
If 4'b is constructed of a laminate of silicon steel plates, the iron loss will be minimal.

Armature core/? Since the magnetic flux density passing through a and its protrusions /#a, ///b does not change, there is no iron loss.

When each armature coil is energized from a DC power source, it rotates as a DC motor, and the losses are only copper loss and mechanical loss, so a highly efficient motor can be obtained. Furthermore, there is an effect that torque ripple can be obtained without any torque ripple. Since there is no position detection element and semiconductor circuit, there is an effect that a heat resistant and inexpensive brushless motor can be obtained.

Since there is no phase switching, there is no generation of counter torque.

Therefore, there is an effect that a high speed electric motor can be obtained.

The principle of drive torque generation is similar to that of the well-known brush-type, lap-wound DC motor, so it is characterized by the ability to obtain a high-output DC motor.

When the rotor +a is driven in the direction by the drive source, an induced voltage is generated in each armature coil, so if the armature coils are connected in series and the induced voltages are added and derived, a generator is obtained. For small output, it can be used as a tacho generator.

The effect is the same as when used as an electric motor.

This is an effective method because there is no ripple in the output voltage.

The embodiment shown in FIG. 9(C) is the armature coil of FIG. 9(b)! The difference is that the protrusions on both sides of the ia are made to protrude so as to accommodate the armature coil 5a therein as shown in the figure.

Due to the above-mentioned configuration, the opposing area between the protrusion and the outer rotating surface of the rotor IIa increases, so that the magnetic resistance becomes smaller.

Therefore, the magnetic flux density of arrows 211a and 24''b and the arrows,
There is an effect that the magnetic flux density of 23a increases and the output torque increases.

Since the shape of the armature becomes a little complicated, it is preferable to construct it from a sintered body of silicon steel powder.

A sectional view taken along the dotted line F in FIG. 3(a) in the direction of the arrow is shown in FIG. 3(d).

In FIG. 9(d), an armature coil 5a indicated by a dotted line is wound around the armature core /, ja.

Projections are provided on both sides of the armature coil 5a (both sides in the direction perpendicular to the plane of the paper), and the end faces thereof face the N-pole surface of the rotor +a with a slight gap interposed therebetween.

The lower end surface of the right protrusion /R of the armature core faces the S pole surface of the rotor llb with an air gap interposed therebetween.

Therefore, the magnetic flux of the north pole of the rotor 9a passes through the protrusion /4'b and is closed at the south pole of the rotor zb. This magnetic flux is indicated by the arrow 211. in FIG. 9(b). It is not shown as u/Ia or u/Ib, but is shown as magnetic flux.

The configurations of the armature cores and protrusions of other armature coils are also similar.

The same objective can be achieved by configuring the configuration shown in FIG. 9(b) as shown in FIG. 9(e).

In FIG. 9(e), the open end of the magnetic path of the U-shaped mild steel piece 23 is fixed in close contact with the lower side of the armature core /, ja instead of the downward protrusion of the armature core /, ja. .

Since the U-shaped mild steel piece 23 has a shape that completely accommodates the lower part of the armature coil ja, only the magnetic flux (arrow 23a) is caused by the armature coil ja, and the dotted line 2
The magnetic flux of 3b becomes a significantly small amount. Since the magnetic flux of the rotor lIa is indicated by the arrows 24a, J, and lIb, the ninth
The rotor <ja is driven in the direction of the arrow as in the case of FIG.

This embodiment is an effective means when the rotor qa is a magnetic rotor, as in the embodiment described later with reference to FIG. 2(C). In the case of a magnetic rotor, the magnetic permeability is about the same as that of air, so in the case of Fig. 9(b), the magnetic resistance of the magnetic flux shown by the arrow 3a becomes thicker (the magnetic flux density becomes smaller and the output torque is reduced). This is because it decreases.

As for the magnetic flux due to energization of the armature coil, in addition to the magnetic flux effective for torque as indicated by the arrow 23a, magnetic flux ineffective for torque is generated.

One of them is that the dotted arrow 2/ in FIG. 3(a) has the disadvantage of generating counter torque. Projection part/4'd/47e,/
Since the magnetic flux from the north pole of the rotor 4a passes through /%f, a counter torque is generated. At the protrusion/da θ, the directions of the magnetic fluxes due to the armature coils Arc and 5cl are opposite, so less counter torque is generated, but at the protrusion/'I
A counter torque is generated at d, /'If.

The magnetic resistance through which the magnetic flux of arrow 23a passes is the first magnetic resistance, the magnetic resistance through which the magnetic flux of arrow 2/ flows through is the magnetic resistance No. 1, and the dotted line J
When the magnetic resistance of the magnetic flux passing in the direction is called the third magnetic resistance, the first magnetic resistance is configured to be significantly smaller than the second and third magnetic resistance.

Therefore, the magnetic flux effective for torque becomes significantly large, and there is an effect that the output torque or power generation output can be increased.

The reason why the third magnetic resistance increases is due to the gaps and protrusions shown by the arrows /2a, /2b, ... in Figure 3.
This is because there are opposing gaps between the rotors 9a and 9b. Therefore, it is necessary to adjust the gap length to increase the output torque.

The above-described magnetic path needs to be composed of a magnetic material having a sufficient cross-sectional area to avoid magnetic saturation.

It is possible to increase the number of rotors lIa, 4(b) in FIG. 2(a) and arrange them in parallel, and to correspondingly increase the number of armatures in FIG. 3(a).

If the armature of FIG. 3(a) is configured as shown in νth glaze (b), the above-mentioned 3rd and 4th magnetic resistances can be increased to obtain a highly efficient electric motor.

Next, the details will be explained.

In FIG. 3(b), the armature core /, ? a, /,

There is a protrusion in the magnetic path indicated by dotted line 2/, which is the No. 1 magnetic resistance.
Only Goo 3 is present, and the magnetic resistance increases significantly. The situation is the same for the other protrusions /'I-7, /'I-2, /'I-'I. Also, the third magnetic resistance in the circumferential direction indicated by the dotted line J is The air gap between the armature cores increases 6. Therefore, most of the magnetic flux from the armature coils passes through the magnetic yoke (indicated by symbol 23 in Figure 7(e)), increasing the output torque. It has the effect of increasing efficiency.

FIG. 2(b) shows another embodiment of the device of the present invention.

In FIG. 2(b), members other than the rotors 10a, 10b, the mild steel cylinder 10, and the excitation coil 9 have the same configuration as in FIG. 2(a).

Since it performs the same function as the rotors 9a and +b, it has the same function and effect as an excitation type DC motor as the case shown in Fig. 2(a).It also has the same function as a generator. Therefore, the object of the present invention is achieved.

Next, the embodiment shown in FIG. 2(c) will be described.

In Fig. 2 (C), the rotating shaft has a cylindrical column 1 made of mild steel.

The outer circumferential surface is uniformly magnetized to N and S poles, respectively.

Therefore, the magnets lOc and lod become rotors, and the outer circumferential rotating surface is uniformly magnetized to N and S poles, and performs the same action as the rotors 4Za and 4Zb in FIG. 2(a), so the dotted line B The outer part shown by is the outer casing //, armature core /, ? in Fig. 2(a). a, /,? b,... and the protrusion /a, /'lb,...armature coil 5a,...! ib
, . . . When configured with the bearings 3a and Jb, it becomes a DC motor or generator having the same effect.

Therefore, the object of the present invention can be achieved.

Figures S (a), (b), and (c) show other embodiments of the apparatus of the present invention. In Fig. S(a), the outer casing /ka, /! b are made of a non-magnetic material such as plastic material or die-cast aluminum, and are fitted together at the outer periphery. Ball bearing 3a...?
A rotary shaft l is rotatably supported by b, and a central portion of a disc-shaped magnet rotor /9 is fixed to the rotary shaft l.

The outer periphery of the magnet rotor 9 is magnetized as a north pole, and the inner periphery is magnetized as an south pole.

The mild steel disk/9a is attached to the N and Ei magnetic pole faces to close the magnetic path. On the magnetic pole surface of the lower surface of the magnet rotor /q, there are an armature core and an armature coil 5a, ! ib,... are facing each other.

Details of the above-mentioned armature will be explained next.

Armature as seen from the direction of arrow P in Fig. S (a) /A, /
A plan view of A-1 is shown in FIG. 7(a).

In FIG. 7(a), the armature on the circumference is expanded into a straight line, and the entire circumference, that is, the EAO degree section is shown as a symbol. Armature core '12 includes armature coil 3a,! rb, .
It is twice the width of 12e.

The protrusions protrude from both sides of each armature coil, and the armature coils are arranged at equal pitches.

The armature core and its protrusions are made of mild steel.

The arrow 113a is the width in the radial direction of the north pole of the magnet rotor /q, and the armature coils face each other with a gap in between.

The protrusions 9ua, 4 (ub, . . . ) face the S pole of the magnet rotor /q, which is the width of the arrow /I3b, with a slight gap therebetween.

A cross section taken along the dotted line F in the direction of the arrow is shown in FIG. 7(C).

FIG. 7(b) is a cross-sectional view taken along the dotted line J from the direction of the arrow. are tightly fixed. The lower surface of the yoke IItI faces the N-pole rotating surface of the magnet rotor /9 with a slight gap therebetween.

Such a protrusion is shown as a stop in FIG. 7(C).

The lower surface of the protrusion +xb in Fig. 7(C) faces the S-pole rotating surface with an air gap. Therefore, the magnetic flux of the N-pole is distributed between the magnetic yoke q, the armature magnetic core, and the protrusion mites. It passes through a, ψ and b and is closed at the S pole.

Other armature coils 5'b, 5C,...! rd and protrusion'
12 a r 'i'=2 b + . . . The above-mentioned configuration is the same for the armature magnetic core. The reason why the output torque can be obtained from the armature coil 5a will be explained.

In FIG. 7(d), the open magnetic flux of the magnet rotor 19 is indicated by arrows 24(, 211a, 2'lb), and is closed at the south pole via the protrusions 2a and +Jb.

The magnetic flux due to the armature coil 5a is indicated by a dotted arrow 23b and a solid arrow 23a. The magnetic flux of arrow 23a is
Since the magnetic flux at arrow 23b passes through the space above,
The magnetic flux is almost exclusively the one indicated by the arrow 23a.

The magnetic flux on the right side of yoke <z+ is the sum of the arrows 23a and x+b, and the magnetic flux on the left side is the difference between the arrows 23a and 211a, so the magnet rotor /9 moves in the direction of the arrow due to magnetic repulsion. driven in the direction.

The situation is similar for other IT armature coils, so the magnet rotor 19 becomes a DC motor driven in the direction of the arrow, and when the magnet rotor 19 is driven by a drive source, it becomes a generator.

The seven magnetic paths of the magnetic flux obtained by energizing the armature coils pass through the aforementioned yoke U, the magnetic resistance of the magnetic paths is the first magnetic resistance, and the other magnetic path is the one that passes through the protrusion 4Z2a.
, 4'2b, . . . and is closed at the end thereof, as shown by the arrow U/ in FIG. 7(a), for example. This magnetic resistance is called a second magnetic resistance, and the other magnetic path is closed by passing through the armature magnetic core value in the direction of the dotted line J, and this magnetic resistance is called a third magnetic resistance.

The No. 1 magnetic resistance has protrusions 111a, 112b,...
It is noticeably thicker because the opposing distance between its ends is large.

The third magnetic resistance has a large value because the length of the armature core Q in the direction of the dotted line J is less than 360 degrees and there is a gap in the opposing portion.

Therefore, the first magnetic resistance is extremely small, and the amount of magnetic flux effective for the output torque indicated by the arrow λ3a increases, making it an effective means.

If the armature core Q is divided into armature coils 5a and 5b and armature coils 3c and 3d, the armature coils can be easily attached.

After attaching the armature coil to the armature core value, see Figure S (
Fit the armature core values into the four parts (not shown) of the outer casing 15kl in a). At this time, the armature coil part needs to be housed inside as a deeper four parts. In the embodiment shown in FIG. S(b), the outer casing /3a in FIG. S(a) is removed, and the portion corresponding to the outer casing 151) is indicated by the symbol /SC.

Symbol /3c has the feature that it can be constructed flatly because it can utilize 7 parts of the main body of, for example, a hard disk that uses an electric motor. That is, part ISC of the main body also serves as the outer casing/Sb. A rotary shaft is rotatably supported by Seel bearings 3a and 3b provided on the main body, and the center portion of the bottom surface of a rotor made of a cup-shaped mild steel plate is fixed to the lower end of the rotor.

A magnet rotor /q (same as in Fig. S (a)) is attached to the rotor /9a, and the magnetic paths of the N and S poles are closed.

The armature cores /A,, /B-/ have the same configuration as those with the same symbols in Fig. 3(a), so the magnet rotor /9 has the armature coil, ! ia,! ib...
The object of the present invention is achieved by being driven by energization.

The embodiment shown in FIG. 6(a) has a configuration in which the armature shown in FIG. 7(a) is divided into nine pieces.

Armature magnetic cores /Aa, /Ab, . . . are fixed to the outer casing /Sb with equal pinches along the circumferential surface, and armature coils 5a, 5b, . . . are wound around each of them. There is.

Projections 32 on both sides of armature core /Aa, /Ab,...
a.

32b, 33a, 33b, ''. are opposed to the S-pole rotating surface of the magnet rotor/9 with a slight gap therebetween.

Although not shown, on both sides of each armature coil there is a U-shaped mild steel yoke (Fig.
) The open end of the magnetic path of the yoke (corresponding to yoke/6 described later) is tightly fixed to form a magnetic path, and the center part of the U-shaped yoke is slightly in contact with the N-pole rotating surface of the magnet rotor/9. They face each other with a gap in between.

Details of the above-mentioned armature will be explained with reference to FIGS. 3(a)(1))(C).

Figures 3(b) and 3(c) are respectively indicated by arrows G in Figure 3(a).
, is a view seen from the H direction.

The open ends of the magnetic path of the U-shaped mild steel yoke/A shown in FIG. 3(C) are closely fixed to the left and right sides of the armature coil 5a in FIG. 3(a), but are omitted from the illustration. Not yet.

In FIG. 3(b), the U-shaped yoke /6 is connected to the magnet rotor /? through a slight gap. It faces the N-pole rotation surface of.

Projections 32a, 3J! The end face b faces the S-pole rotating surface with a slight gap in between. A dotted line l indicates the position of the rotation axis. Therefore, the magnetic flux of the north pole passes through the U-shaped yoke/A and the protrusions 32a and 32b, and passes through a magnetic path closed at the south pole.

In FIG. 3(c), the magnetic flux due to the armature coil &a is indicated by a dotted arrow 23b and a solid arrow 23a, but the magnetic flux indicated by the dotted arrow 23b passes through space, and the magnetic flux indicated by arrow 23h passes through a magnetic material, so the former becomes extremely small, and the amount of magnetic flux in the latter becomes large.

The magnetic flux of the north pole is the arrow! 4a, 24'b, the magnetic flux on the right side is the sum of the magnetic fluxes 23a and the magnetic flux on the left side is the difference between the magnetic fluxes 23a and 21Ia.

Therefore, the magnet rotor /q is rotated by obtaining a driving force in the direction of the arrow. The above-mentioned circumstances are the same for other armature coils, so they are DC motors.

When the magnet rotor/9 is rotated by a drive source, it becomes a generator that generates an induced voltage in the armature coil.

The magnetic path of the magnetic flux caused by the armature coil is 1 in addition to the magnetic path described above.
There is one. That is, it is a magnetic path passing through the magnetic core/4a and the protrusions 32h and 32b. The magnetic flux passing through this magnetic path does not contribute to the output torque (but generates counter torque and becomes an ineffective magnetic flux, but since the gap between the ends of the protrusions 32a and 32b is large, the magnetic resistance is large (, Arrow 23a has a small amount of magnetic flux and is effective for torque
This has the effect of suppressing a decrease in the amount of magnetic flux and reducing the generation of the above-mentioned counter torque.

The magnetic flux in the circumferential direction due to the root element coils passing through the magnetic cores /Aa, /Ah, . This point is different from the case of FIG. 7(a), and the efficiency is good. Other effects are the same as in the previous embodiment.

The cross-sectional area of each magnetic path described above must be such that the magnetic flux will not be saturated.Next, the embodiment shown in FIG. S (C) will be described.

In Fig. S (c), the outer casings 15a and 3b made of plastic material or aluminum die-casting are fitted at the outer periphery, and ball bearings 3a and 3b provided in the respective medium heating parts are provided with rotating parts. A shaft l is rotatably supported.

On the rotation axis l, there is a disk-shaped magnetic rotor, ? The center part of / is fixed.

Both sides of the outer periphery of the magnet rotor 3/ are magnetized to N and S poles as shown.

Symbols /g, /g-/ are armature cores fixed to the outer casing /, ltb, and armature coils 5a, 5b, . . . are attached thereto.

Symbol 30.30-7 is a mild steel yoke embedded in the outer casing 15a, which together with the armature magnetic cores /g and /g-/ constitutes a magnetic path that closes the magnetic flux of the N and S poles.

Next, armature core /g, /g-/, armature coil Sa,

FIG. 6(b) is a plan view of the outer casing /jb viewed from the direction of arrow P, and FIG. 6(c) is a plan view of the outer casing 15a viewed from the direction opposite to arrow P.

In Fig. 2(b), armature coils ja, 5b, . . . are wound around armature cores /ga, /gb, . . . made of U-shaped magnetic material as shown in the figure. Ru.

The magnetic cores /ga, /gb, . . . are fitted and fixed in recesses provided in the outer casing /&b, and the armature coil portion is an even deeper recess.

The ends (dot points) of the magnetic cores /ga, /gb, ... are upright parts 3'la, 311b that are bent in a direction perpendicular to the plane of the paper.

The ends of a, 3'lb, , Baa, 33b, - are inserted to close the magnetic path.

The details of the armature coil and its magnetic core are shown in Figure 3(d)(e)(
f) will be explained in detail.

FIGS. 3(e) and 3(f) are views of FIG. 3(d) as seen from the directions of arrows G and H, respectively.

The open end of the magnetic path of a U-shaped magnetic yoke/g, not shown in FIG. 3(f), is closely fixed to the magnetic core /ga in FIG. 3(d), but is not shown for purposes of illustration.

In Fig. 3(e), the magnetic flux of the N pole of the magnet rotor 3/ (the position of the rotation axis is indicated by the dotted line/) is as follows: U-shaped yoke/g, magnetic core/ga, upright part 3hiroa, mild steel York 37
It is a magnetic path that passes through a and is closed at the south pole. The mild steel yoke 37a faces the S-pole rotating surface of the magnet rotor 3/ with a slight gap in between, and the center portion of the U-shaped yoke 1g faces the N-pole rotating surface with a slight gap in between. .

The magnetic flux of the north pole mentioned above is indicated by the arrow,
24a, 211b.

The magnetic flux due to the armature coil 5a is indicated by a dotted arrow: 13b.

The magnetic flux of arrow 2310, shown as solid arrow 23a, is
Since it is closed through a space, it is extremely small, and most of the magnetic flux becomes the magnetic flux shown by the arrow 23a.

The magnetic flux on the right side of the armature coil 5a is indicated by arrow λ3a and arrow 2.
11b, and the magnetic flux on the left side is the sum of arrow 23a and arrow 2.
<I! Since there is a difference in a, the magnet rotor 3/ generates a driving torque in the direction of the arrow and rotates.

Since the above-mentioned circumstances are the same for the other armature coils, the magnet rotor 3/ becomes a DC motor driven in the / direction.

When the magnet rotor 31 is rotated by a drive source, generating power is generated in the armature coil and becomes a generator.

The cross-sectional area of each magnetic path is set to a size that does not saturate the magnetic flux. The magnetic flux generated by the armature coil 5a passes through a magnetic path closed through the magnetic core/ga and the mild steel yokes 3a and 37b, but since the distance between the mild steel yokes 37a and 37b is large, the amount of magnetic flux is extremely small.

Magnetic core/+! +a, /gb, /,! rc, /
,? The magnetic flux passing through d in the circumferential direction also has a large magnetic resistance, so
The amount of magnetic flux is extremely small.

If the former magnetic resistance is called the second magnetic resistance, the latter magnetic resistance is called the third magnetic resistance, and the magnetic resistance of the magnetic flux passing through the U-shaped yoke/g is called the first magnetic resistance, then the first magnetic resistance is The magnetic resistance becomes significantly smaller than the third magnetic resistance.

Therefore, the magnetic flux indicated by the arrow 23a, which is effective for output torque, becomes significantly thicker (and becomes an effective means).

Other effects are the same as in the previous embodiment.

The embodiments shown in FIGS. 3(g) and 3(h) show means for further increasing efficiency and output.

FIG. 3 [Co., Ltd.] is a diagram in which the protrusion 3.2a of FIG. 3(a) has been removed. The other armature coils are similarly constructed. The other armature coil parts have the same configuration.

Dotted line where the magnetic flux from the armature coil passes! As for the magnetic resistance of the magnetic path indicated by /a, since there is no protrusion 3.2a, the portion of the magnetic path passing through the air increases, and the second magnetic resistance increases significantly.

Therefore, there is an effect of increasing the amount of magnetic flux effective for the output passing through the yoke/B in FIG. 3(C).

FIG. 3(h) shows the upright part 3 of the magnetic core/ga in FIG. 3(d).
4'b and the mild steel yoke 3'/b connected thereto have been removed. The other armature parts have the same configuration.

Dotted line through which the magnetic flux from the armature coil passes, the second line indicated by 2/a
Since there is no mild steel yoke 37b and no upright portion 34'b, the magnetic resistance of the U-shaped yoke/
This has the effect of increasing the amount of magnetic flux effective for the output passing through g.

In the apparatus of the present invention shown in FIGS. 2(a) and 2(b), even when rotating at a high speed of approximately 700,000 revolutions per minute, the rotor &a,llb.

/θa and #7b are made of mild steel, which prevents damage due to centrifugal force. In the case of FIG. 2(a), if the outer periphery of the magnet ti is covered with a nickel sleeve 3,
Centrifugal force damage is prevented.

In the embodiments shown in FIG. 2(c) and FIGS. S(a), (b), and (C), the rotor is a magnetic rotor, so its magnetic permeability is about the same as that of air. Therefore, the second magnetic resistance is small (
, arrow 23 is effective for the output torque by the armature coil.
It is characterized by an increase in the amount of magnetic flux a. In addition, the generation of counter torque is also reduced.

Next, the features when the device of the present invention is configured as a generator or an electric motor will be described below.

Since a constant current of l always flows in the armature coil in the l direction, there is no change in the stored magnetic energy. Therefore, in the case of an electric motor, an output torque without torque ripple can be obtained, and in the case of a generator, a voltage output proportional to the rotation speed without voltage ripple can be obtained. Furthermore, when there is a speed fluctuation, a voltage output with quick response can be obtained, so it can provide an effective technology as a tacho generator.

Since it has a brushless configuration and does not require an electronic circuit for controlling energization of the armature coil, a small, inexpensive, and heat-resistant generator or motor can be obtained.

It has the feature that a rectifier for switching the energization of the armature coil is not required.

Since there is no storage and release of magnetic energy in the armature coil,
Even at high speeds, there is no generation of counter torque, and a high-speed electric motor with good efficiency can be obtained. Furthermore, since there is no iron loss, efficiency is improved.

Since the armature current does not change (nor does its direction change), it has the characteristic of eliminating electromagnetic noise and mechanical vibration.

In the case of an electric motor, by using seven of the multiple armature coils as power generating coils and using the others as torque generating coils, it is possible to control the energization of the armature coils using the output of the power generating coils. Constant speed control can be performed. Since the output of the generator coil does not lag over time,
It has the characteristic of providing accurate and responsive constant speed control.

〔effect〕

First effect: A motor with flat torque characteristics without torque ripple or a generator with no ripple voltage can be obtained.

The second effect rectifier is not required, the structure is brushless, and the energization control circuit for armature current control is eliminated.

Third effect: Since no reaction torque is generated, a high-speed electric motor can be obtained.

The first effect is that there is no iron loss (and no counter torque is generated), so a highly efficient electric motor or generator can be obtained.

Fifth effect: Since the amount of current flowing through the armature coil does not change (and the direction of current flowing does not change either, electromagnetic noise and mechanical vibrations are significantly reduced).

Sixth Effect: In the embodiments shown in Figures d(a) and (b), a high-speed rotating electric motor is obtained, and in the embodiments shown in Figures 2(c) and S(a), (b), and (c), Since the third magnetic resistance can be made thicker, the amount of magnetic flux generated by the armature coil, which is effective for output torque, can be increased.

Since there is no switching of the seventh effect phase, there is no iron loss. Therefore, a soft steel material, or a sintered product of mild steel powder or silicon steel powder can be used as the magnetic core. Therefore, the configuration becomes easy.
