Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a magnet prime mover for converting magnetic energy into mechanical rotational energy by utilizing a rotating body constituted by a magnet and a magnetic flux pseudo-fixed body, a magnetic pole piece, a synchronous gear, and the like.

[0002]

2. Description of the Related Art An apparatus using a two-axis synchronous gear for extracting magnetic energy of a magnet as mechanical rotational energy is disclosed in Japanese Patent Application Laid-Open No. Sho 62-196062. One magnetic pole of the plurality of magnet elements is oriented radially outward of the rotating body.
In addition, no pseudo-fixed body for efficiently converting magnetic energy into mechanical rotational energy is provided. In addition, since a plurality of magnet elements are permanent magnets, it is difficult to manufacture and control a large-sized device.

[0003]

It is generally recognized that a rotating device utilizing attraction or repulsion between a permanent magnet or a DC-excited electromagnet does not rotate continuously because the sum of the rotation vectors in one round becomes zero. . The magnetic field of the magnet has continuous kinetic energy in a certain direction due to electron spin, but it is considered difficult to convert the kinetic energy into mechanical rotational energy.

[0004] The magnetic pole portion of a rotating body of a device that converts magnetic energy into mechanical rotational energy has an interaction with a magnetic flux from an external magnetic pole as compared with a magnetic pole portion of a rotor such as an ordinary synchronous motor or a synchronous generator. The direction and strength change significantly, and it is necessary to respond to the change. For this reason, the eddy current loss and the hysteresis loss are likely to increase, and as a result, the output is reduced, and the output is low for the weight of the device or the magnet, and the practicability is low. In order to solve this problem, it is required to develop an electromagnetic rotating machine having a form and a magnetic circuit along a mechanism for converting magnetic energy into mechanical rotational energy.

The present invention efficiently converts magnetic energy into rotational energy by using a magnet rotating method different from the conventional two-axis type rotating device and a new rotating body employing a pseudo-fixed body made of a metal such as copper or aluminum. It is an object of the present invention to provide a structure and an embodiment of a magnet motor that can be used.

[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A rotating body of a magnet motor according to the present invention is broadly divided into a plurality of magnets 3 having the same radius and the same magnetic pole direction at circumferentially equally spaced positions on a rotating shaft as shown in FIG. An outer-magnet-type magnetic circuit in which a pseudo-fixed body 4 made of a non-magnetic and good electric conductor for suppressing magnetic flux fluctuation is arranged in a magnetic flux path passing through both magnetic pole surface directions of the magnet and the direction of the rotating shaft side so as to be parallel to the axis. And a quasi-fixed body that suppresses magnetic flux fluctuations by disposing a magnet coaxially with the rotation axis and replacing the magnet part of the rotator of the external magnetic circuit with an axial gap as shown in FIG. There are two rotating bodies of the inner magnet type magnetic circuit having the above-mentioned structure.

The pseudo-fixed body is made of a non-magnetic metal having good electric conductivity (eg, copper, aluminum, etc.). When another external magnetic pole acts on the magnetic pole of the rotating body, the pseudo-fixed body is separated from the magnetic pole of the rotating body. For the purpose of partially suppressing the fluctuation of magnetic flux among the lines of magnetic force, the magnetic flux from that part is passed through the metal in advance, so that the sudden fluctuation of the magnetic flux from the magnet part passing through the metal can be suppressed. It acts to control and works under Lenz's law. Since no general name was found, it was called a pseudo-fixed body in the sense of suppressing fluctuations in magnetic flux.

The magnetic flux from each magnet of the external magnet type rotating body diverges and converges from the magnetic poles N to S, and the magnetic flux diverging outward and converging outward from the rotating shaft side is the rotating body. , While the magnetic flux directed toward both pole faces and the rotation axis passes through a pseudo-fixation which prevents dynamic fluctuations.

The magnetic flux that diverges and converges from the pole pieces in the respective gaps of the inner magnet type rotating body also diverges outward as viewed from the rotation axis, and the converging magnetic flux passes through the space outside the rotator, As in the case of the external magnet type, the magnetic flux directed to the surface direction and the rotation axis side passes through a pseudo-fixed body that prevents dynamic fluctuation.

As shown in FIG. 6, the distance between the two rotating bodies changes periodically with the magnetic poles on the other side as they rotate, and the two rotating bodies interact with each other, and the magnetic field or the magnetic field lines around the magnetic poles repeats dense and sparse. When there is no pseudo-fixed body, as shown in FIG. 7 (a), the distribution of lines of magnetic force around the magnetic pole when the magnetic poles approach each other tends to be symmetrical on the left and right sides of the magnetic pole. By suppressing the dynamic fluctuation of the magnetic field lines facing the rotation axis side, an asymmetric state as shown in FIG. 7B can be periodically realized, and the magnetic field lines facing outward from the magnetic poles of each rotating body can be interposed. At which the magnetic energy having a rotational direction is efficiently converted into mechanical rotational energy. Further, the direction in which the magnetic poles exert an action with the other magnetic pole is transverse and unidirectional to the direction of the lines of magnetic force connected between the magnetic poles of the respective rotating bodies, and is pulsating. For this reason, the magnetic flux distribution in the pseudo-fixed body during operation is such that the peak component from the lateral direction when the magnetic pole approaches is averaged by the steady magnetic flux band when the magnetic pole separates, and has a form of inclination.

When the rotating body having such a structure is rotated, another magnetic pole or a line of magnetic force having a relatively different angular velocity is applied to the magnetic pole portion from the outside periodically or intermittently to apply suction or repulsion from one direction to rotate. When the rotation of the body is accelerated or decelerated, the conversion of magnetic energy into mechanical rotation energy or, conversely, the conversion of mechanical rotation energy into magnetic energy is performed. When two rotating bodies are rotated in reverse by a synchronous gear and opposed to each other so as to repel corresponding magnetic poles on the other side, and the two magnetic poles are rotated in a relationship of leading and lagging in the rotational direction, the cycle becomes The magnetic pole on the leading side is accelerated from the magnetic pole on the lag side, and the magnetic pole on the lag side receives a torque decelerated by the magnetic pole on the leading side, and the relationship between the non-driving side rotating body and the driving side rotating body is established. When the adjacent magnetic poles are approaching and moving away from each other, there is a relative difference in angular velocity between the corresponding magnetic poles.

At this time, the torque of the driven rotating body, which is the accelerating side, and the decelerating side are determined by the combination determined by the direction of the magnetic pole of the magnet and which of the left and right rotating bodies is the leading side. The sum of the rotation vectors obtained by combining the drive side reaction torques does not become zero, and the torque of the driven rotating body that is accelerated is large, and the reaction side torque that is decelerated is small. Or the opposite combination would be the opposite minus side. FIG.
If a combination is selected such that the sum of the combined rotational vectors is positive, such as 8, 9, the magnetic energy is converted into mechanical rotational energy expressed by the product of the rotational average torque and the peripheral speed. That is, when approaching and moving away from the corresponding two magnetic poles of each rotating body, the combination of the positive side such that the moment in the rotating direction remains in the action and reaction between the corresponding magnetic poles in the rotational direction. It is good to use in a magnet motor. When the rotation direction is reversed in FIG. 6, the relationship between the leading side and the lagging side is reversed, but since the relationship between the left and right is switched, there is no change in the combination.

If the combination on the minus side is selected, the rotational energy is converted into magnetic energy, so that it becomes a braking device. To continue the rotation, it is necessary to input the mechanical rotational energy. Fig. 6 and 2 poles
In FIGS. 8 and 9 showing the combination of the rotating body with three poles or three poles and the magnetic pole direction, the front side of the drawing is represented by the S pole, and the rear side is represented by the N pole.

It is preferable to use a non-magnetic stainless steel or the like for the two rotating shafts. In the case of a small magnet motor, an external magnet type magnet using a cylindrical neodymium / iron / boron magnet or a cylindrical ferrite magnet for the magnet. A prime mover or an inner magnet type prime mover using a hollow cylindrical neodymium / iron / boron magnet is suitable. The controllability is improved if one of the rotating magnets is a permanent magnet and the other is a DC-excited electromagnet. It is preferable to use a DC-excited electromagnet for each rotating body as the magnet of the large magnet motor. When the number of magnetic poles is one, it is necessary to pay attention to the shape of the pseudo-fixed body, which also has the function of balancing the rotation, but when the number is two or more, it is preferable to form the pseudo-fixed body symmetrically about the rotation axis.

If the number of magnetic poles is too large, the efficiency is reduced because it is necessary to reduce the difference between the leading and lag angles as the number of poles increases. As for the magnet, the dimensional ratio of the diameter to the thickness is important, and a thin or thin shape is not good. The shape is not limited to a cylindrical shape or a hollow cylindrical shape, but may be a polygonal column shape or the like. Alternatively, as a modified example, one magnet 3 having a magnetic pole direction coaxial with the rotation axis and having a plurality of convex portions in the outer circumferential direction as shown in FIGS. 10 and 11 is used, and the magnetic pole pieces 11 are arranged on both magnetic pole surfaces. Further, a rotating body having a structure combining the characteristics of the outer-magnet type and the inner-magnet type magnetic circuit in which the pseudo-fixed body 4 is arranged may be used. Further, it is preferable that magnetic pole pieces 11 and 11A made of a soft magnetic material having the same cross section as the magnet are arranged on both magnetic poles of the magnet of the external magnet type motor.

Another effect of the pseudo-fixed body is that if a material having a small electric resistance is used as a short-circuit plate or short-circuit ring for the magnetic flux, it also prevents the fluctuation of the magnetic flux inside the magnet and reduces the eddy current loss and the hysteresis loss. Become smaller. In addition, when one magnet is arranged in the outer magnet type magnet prime mover and when there is one axial gap in the inner magnet type magnet prime mover, the magnetic flux passing through the rotating shaft side extends to a region beyond the rotating shaft, so it is pseudo-fixed. It is preferable to extend the body, and it also serves as a weight to balance rotation.

The pseudo-fixed body is preferably a lump made of a member such as copper or aluminum. However, the pseudo-fixed body is made of a copper plate or the like having a width in the axial direction, and the magnetic flux is simulated simply by surrounding each magnet, each magnetic pole piece, and each axial gap. There is an effect as a fixed body, and there is also an effect only by arranging a copper plate or the like on the side surface near the corresponding magnetic pole of the other rotating body among the plates surrounding the magnetic pole of each rotating body. Also, in order not to impair the movement of the magnetic field lines facing outward from each magnet or magnetic pole, which is an important role in the conversion to rotational energy, the magnet whose magnetic field lines face outward and the copper plate etc. of the pole piece (such as a short-circuit plate) Action) should not be too thick. For the shape of the pseudo-fixed body, consider the shape of the magnet to be used, the internal resistance, the residual magnetic flux density, the electric resistance of the pseudo-fixed body, the size and weight of the device, etc. .

The width in the axial direction of the pseudo-fixed body of the external magnet type magnetic motor must be larger than the length in the magnetic pole direction of the magnet, and is preferably at least twice the length of the magnet in order to improve the efficiency. . In the case of an internal magnet type magnet motor, the shape of the yoke and the pole piece made of soft magnetic material is determined so that the gap is about half the length between the magnetic poles of the magnet, and the width of the pseudo fixed body is determined by the gap and both poles. The width is the same as the length including the piece and both yoke, and the plate yoke surrounds the yoke, pole piece and gap at the same time,
It is preferable to adopt a structure in which the same material as that of the pseudo-resistor is poured into each of the axial gaps and the inner space surrounded by the plate-like material.

As the two synchronous gears, spur gears having the same number of teeth are used if the number of magnetic poles of each rotating body is the same. It is preferable to use a magnet whose radius is approximately the radius from the magnet or pole piece of the rotating body to the rotation axis.If the size is large, the space between the rotating bodies spreads. Interaction decreases. The material may be iron as long as the effect of the magnetic field can be ignored, but stainless steel, brass,
Nylon or the like may be used. If the inertia of both rotating bodies is made large in order to transmit the torque as a pulsation from the driven side, which is the leading side, to the driving side, which is the lag side, the life of the gear is prolonged. The output is preferably taken from the non-drive side shaft, which is the leading side. It is preferable that the gap between the magnetic poles on the leading side and the lagging side of each rotating body is narrowed so as not to contact even at the time of closest approach.

Another set of rotating bodies in which the driving side and the driven side are interchanged are additionally arranged on the driving side and the driven side rotating bodies of the first rotating shaft and the second rotating shaft, and the mounting angle is shifted. By adding a rotating body on the driving side or non-driving side as a parallel 3-axis or 4-axis type, transmission torque and pulsation torque can be reduced and the directivity of the magnetic field lines can be improved, so that output can be increased and gear wear can be reduced. Etc. are effective. It is also possible to connect a synchronous generator or a synchronous motor to each rotating body and electrically connect the generator and the motor to omit or simplify the synchronous gear.

The starting device may be of a manual type with a small magnet motor, but if it is large, a starting motor or the like may be used. Unlike the characteristics of an ordinary electric motor, the torque rotation speed characteristic of a magnet motor does not have a synchronous rotation speed, and there are few factors that limit the upper limit of the rotation speed. In the case of a magnet prime mover using a permanent magnet, since the generated torque does not decrease even when the rotation speed increases, it is necessary to arrange a load and braking device such as a generator. No torque is generated at the time of stop, but torque starts to be generated when rotation is started. The direction of rotation is determined by the direction in which rotation was given at the start.

In a large magnet motor used in a power plant or the like,
It is more advantageous to use a DC-excited electromagnet than to use a permanent magnet as the magnet because of the ease of manufacture, control, maintenance, and economy. In particular, in the case of the electromagnet type, it is preferable to use an inner-magnet type motor that requires only one arrangement around the rotating shaft. Control and braking can be easily performed by changing the intensity and direction of the exciting current. The power supply to the electromagnet may be of a brushless type using a brush and a slip ring or by incorporating a power generating coil and a rectifier into a rotating body. Reversing either the direction of the magnetic pole of the magnet or the relationship between the advance and delay of the left and right rotating bodies acts as a braking device that generates less heat, and the rotational energy is converted to magnetic energy.

The magnetic flux pseudo-fixed body is a copper plate having a width of 60 mm and a thickness of 1 mm, and is arranged so as to surround each magnet. For fixing the magnet to the rotating shaft, a stainless plate, bolt, nut, set collar, etc. are used. Two synchronous gears made of iron having 65 teeth and a module of 1.25 were used. The distance between the magnetic poles of each rotating body is adjusted to about 1 mm at the time of closest approach. If the rotation shaft is rotated in either direction by hand, the rotation starts. However, when the rotation is heavy without starting, the relationship between the leading side and the lagging side of each rotating body is opposite to the magnetic pole direction.

In this type, the distance between the magnetic poles of each rotating body was adjusted to about 10 mm at the time of closest approach. Rotate the rotating shaft in any direction by hand to start it. Example 1,
2 In both cases, load equipment is arranged so that the number of rotations does not increase too much.

[0030]

According to the present invention, a synchronous gear is used, but the surface of the rotating body can be finished in a smooth curve by adopting a pseudo-fixed body of magnetic flux and disposing it in parallel with the rotation axis in the magnetic pole direction. The structure is such that the magnetic poles can enter the front and back of the magnetic pole of the other party, so that the loss of the magnetic pole portion is small and the magnet motor has a simple structure having an efficient rotating body.
