Abstract

PROBLEM TO BE SOLVED: To solve a problem of a conventional double-inverted motor that it was not applicable to exhaust fans because a slipping point was set around a shaft, and a brush had to be mounted on a casing, which caused a projection of 6 cm for the two brushes, by providing the point at the casing and mounting the brush on the shaft. SOLUTION: The point (5) is set on the casing (1) and a carbon (6) is mounted on the shaft (3a) of each of induction armatures (3) in the motor. When electric current is passed, a rotor (4) rotates and the induction armatures (3) are rotated in the opposite direction to each other. At this time, the point (5) and the carbon (6) have little abrasion because they are positioned around the shaft (3a).

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is characterized by the fact that the power supply device for a contra-rotating motor is used as a point of friction and the carbon provided on the shaft rubs against friction, so that the carbon can be used semipermanently. The present invention relates to a power supply device for a double inversion type.

2. Description of the Related Art A conventional power supply device for a counter-rotating motor is shown in FIG.
Like the AC reverse rotation motor of 292715 {the same as the inventor}, it is called an armature because an induction armature {an induction armature is a stator in an ordinary motor and the stator is fixed. I used words. The armature is a generic term for the generator of the generator and the armature of the electric motor. Since it is difficult to explain with the armature, it is an induction armature. Hereinafter, the induction armature refers to a stator and an armature in an ordinary motor. }, And a squirrel-cage rotor is arranged on the outer side, and electric current is fed by using a brush at a point where the electric current is slipped from the center of the shaft of the induction armature. The supplied current, which uses a capacitor, divides the wiring into two, and one of them passes through the capacitor to accelerate the capacitor cycle by a quarter cycle and become a starting coil.
The other wire is used as the main coil, and the slots are used as magnetic poles in the same cycle, and the starting coil rotates 1/4 of the rotation.
Since the cycle rotates faster, the cycle that rotates here is established.

Utilizing this action, the inner induction armature and the outer rotor rotate, but since the induction armature is not fixed, they rotate with each other due to the reaction force. A wing is a wing attached to a shaft. In a reverse rotation axial flow electric compressor, the wing is attached to the shaft via an induction armature. Hereinafter, the shaft wing is a wing that rotates in the rotation direction of the shaft. }, And by the rotor wings attached to the outer rotor,
Since the wind is sent straight and the number of revolutions of the wings is halved, there is less wind noise and a scent, but the amount of air sent is not inferior. The reason why the 1st stage feather is inefficient is that if it is the 1st stage feather, the wind swirls, and most of the energy disappears as a vortex with no effect. Moreover, since the rotation is physically halved, the power consumption is low.

Also, when a double reversal type motor is used as a shading induction motor, it is also called a shading coil.
A winding short-circuited coil is attached to one of the divided magnetic pole tips to generate a rotating magnetic field by utilizing the delay in the generation of the magnetic field. This method does not require a condenser like a contra-rotating motor for starting a condenser, and can be used for small fans such as ventilation fans. The wear of the brush is the same as that of the contra-rotating motor that starts the condenser. If the slip ring has a diameter of 20 mm, the outer circumference is 60 mm, but at the slipping point, it is 0 mm because it is the center of the shaft. I didn't bald.

As a ventilation device in which the wings rotate in opposite directions, the double counter-rotating ventilation device named in Japanese Patent Laid-Open No. 5499/1993 is used.
Two normal ventilation fans were arranged in front and behind to make a double-inverted type. This is a combination of two ordinary motors and does not require a power supply device such as a slip ring, so no maintenance is required. However, although the capacity was large where two motors were required, the straight wind of the contra-rotating fan was a property that I wanted to install two motors.

Since the present invention also uses an outer rotor electric motor, the advantages of the outer rotor electric motor will be described. Among them, Japanese Patent Application Laid-Open No. 11-4188.
Like the abduction-type squirrel-cage induction motor of No. 3, a thin silicon steel having punched slots is wound with a number of heavy windings to form an induction armature, and a rotating magnetic field is generated by passing an electric current. Also,
A hole for inserting the shaft is provided in the center. A large number of thin silicon steels are stacked on the outside to make a cage rotor with conductive rods and end rings, and a shaft is provided at the center of the cage rotor. The outer cage rotor rotates due to the induction of the magnetic field. At this time, when designing a motor of the same capacity, if the induction armature is placed inside, the diameter of the gap surface becomes large, and
It is efficient because it lowers the secondary resistance. In addition, since the excitation winding is easily wound by arranging it inside, and the excitation winding can be short, the electric resistance of the excitation winding is small.

Further, in its manufacturing method, Japanese Patent Laid-Open No.
In the -28521 outer rotor motor and its manufacturing method, an integral cover having the functions of a bush for protecting the power supply lead (electric cord in the present invention) and a bearing protecting material for protecting the bearing is fixedly attached. Therefore, the assembling property, the quality and the cost can be effectively improved, and the cover for protecting the bearing having the bearing holding portion for holding the bearing is attached to the stator, so that the assemblability and the vibration of the bearing are prevented. Problems such as were being improved at the same time.

Since the reverse rotation axial flow electric compressor uses a flat motor, the flat motor has an axial cap brake motor, and the flat motor has a stator with a gap surface perpendicular to the shaft interposed therebetween. An electric motor with the rotors facing each other.When energized, like the brake motor, an attractive force acts between the gap surface, the stator and the rotor, so the spring is used to bend the force. The spring moves the rotor toward the stator and rotates it with a gap in the braking surface. When the electricity is turned off, the spring force causes the rotor to come into contact with the braking surface and stop abruptly. Further, among flat motors that have been applied, Japanese Patent Application Laid-Open No. 5-344679 {Patent 28816
09 same as the inventor}. This is a type of fan that sends wind. The pressure of the first stage blade does not rise so much, but the air of the seventh stage blade compresses air as much as a centrifugal fan. In addition, since the wind was sent by 7 steps of blades, it acts on the blades on average, so that the blades are not warped. For this reason, reverse injection can be performed with a single switch.

When the synchronous counter-rotating axial-flow electric compressor is started by using the inverter, it consumes less electricity than the reverse-rotating axial-flow electric compressor using the induction motor. The synchronous counter-rotating axial-flow electric compressor uses a permanent magnet for the rotor, and it is necessary to be careful when accelerating the rotation, but the required air volume can be obtained by using the inverter. Further, when the static pressure is increased, it can be easily increased by adding the rotor and the induction armature.

In addition, the electric motor of JP-A-56-68252 is an outer rotor type electric motor and is a ventilating fan or fan, which is different from the viewpoint of the present invention, but some people point out that it can be easily invented from that, so the difference is that. The double reversal type power supply device of the present invention is not necessary because it is not a double rotation type. It is true that the rotor is attached to the outside, and by sharing the motor terminal and the control switch terminal, the number of parts and man-hours can be greatly reduced, and the secondary resistance can be further reduced to reduce the size. Can be designed.

Further, the blower disclosed in Japanese Patent Laid-Open No. 61-31696 is a double reversal dryer using an AC commutator and uses the AC commutator. The induction motor of the present invention is a motor property. It ’s different. In addition, the place where the slip ring is used is different. However, the contra-rotating dryer has blades that rotate in the opposite direction to the blades on the same axis, which has the effect of increasing the blowing efficiency and making it more compact than a blower with the same air volume. The advantages are the same as the present invention.

Further, the double output shaft electric motor of Japanese Patent Laid-Open No. 62-44045 also has the counter-inversion type power supply device of the present invention.
When the rotation is doubled, it requires two pieces of energy, and the two shafts rotate by the distribution of that energy. So
When one shaft was stopped, the other shaft was given rotation. The power supply device was provided via a disk-shaped slip ring at the end of the shaft, but there was much brush friction. Therefore, regular inspection was necessary.

Since the power supply device of the present invention employs a rotary connector, the connector is described in Japanese Patent Laid-Open No. 8-222307, which is a socket device for electrical connection. First, a known device will be described. It is arranged at the center of the ground terminal. However, this ground terminal is not protected, whereas the other contacts are protected by the disk. There is no voltage on the ground terminal, so the ground end tentacle does not seem to be authentic. Furthermore, the central location of the ground contact makes it difficult to come up with releasable closure means by rotation of the disc as with other contacts. Therefore, the closure member of the central housing is movably mounted on the contact support, and a combination drive means is provided between the closure member and the safety disc. In the initial position of the safety disc, the housing of the central contact is closed by the closing member, during the rotation of the safety disc by the cooperation with the combination drive means,
A socket device is provided which is characterized in that the central housing is opened, but the electric power is supplied outside the shaft, and the electric power is supplied from the center of the shaft of the present invention.

For applications filed after 2001,

[0015]

A counter-rotating motor for the outer rotor motor is disclosed in Japanese Patent Laid-Open No. 5-2927.
It is modified like an AC reverse rotation motor of No. 15 and an induction electric element is provided inside and a cage rotor is arranged outside. Electricity was supplied using a brush at the point where it slips from the center of the induction armature shaft. The wear of the brush is 60 mm at the outer circumference when the diameter is 20 mm for the slip ring, but is 0 mm because it is at the center of the shaft at the slipping point, so the brush was hardly bald. However, since the brush is attached to the outside, it could not be used for things such as ventilation fans with limited thickness.

Further, since the slipping point is attached to the shaft of the induction armature, if a too small slipping point is attached to the shaft, it will be damaged when hitting when handling, and a sharp object needs some strength. And needed a big one. That is, if the weight of the induction armature is 1 kilogram, a slipping point of 6 mm or more, which is suitable for the weight, is required. When the slipping point became large, I had to attach a large brush to match it, but usually 3 cm or more of space is required, and there is a total of 6 cm of space.

Therefore, the counter-inversion type power supply device of the present invention is
A reverse rotation type power supply that can be used also for a ventilation fan to reduce the thickness by attaching the slipping point of the AC reverse rotation motor of JP-A-5-292715 to the casing and attaching the brush to the center of the shaft of the induction armature. A device is provided.

However, although the squirrel cage rotor (4) alone rotates, if silicon steel having the rotor (4) laminated in a strip shape is attached, the magnetic flux generated from the induction armature (3) becomes magnetic. Since the leakage flux is reduced by the substance and the rotation is smooth, the slot (4b) is inserted into the laminated product of silicon steel having a small residual magnetism and coercive force with the magnetic substance, and the end ring (4d) is short-circuited. use.

As a result, a large number of induction armatures (3) and a large number of rotors (4) are alternately sandwiched to receive electric energy, and they are rotated in opposite directions by a reaction force and are provided in the induction armature (3). The shaft wing (3b) thus rotated and the rotor wing (4a) provided on the rotor (4) also rotate in reverse.

According to the eleventh aspect of the present invention, in the contra-rotating axial-flow electric compressor power supply device for the counter-rotating type, the shaft (3a) of the induction armature (3) is inserted into the casing (1) via the bearing (2). )
Rotatably attached. Then, a cover (5c) is attached to the casing (1) in the power feeding device,
c) is from the electric cord (5d) through the electric terminal (5d), and the point (5) is pushed by the spring portion (5a) and is in contact therewith. At this time, since the cover (5c) is small and light, even if the point (5) of the protrusion is designed small, it is not damaged.

It is the induction armature (3) that receives the current.
The carbon (6) of the shaft (3a) receives the electric current at the point (5) and is fed from the power supply terminal (6a) to the internal cord (6c).
However, since the carbon (6) has the point (5) at the center of the shaft (3a), it has little friction and hardly wears. To explain this by using the top as an example, the top of the top is in contact with the center point, so there is little friction, so if you press the outside of the top, it will stop easily. The point is that there is little friction. Similarly, it receives current from the end of the other shaft (3a). Then, the other phase current is applied to the cover (5c) with the general-purpose brush (5c).
e) and attach the slip ring (6) to the shaft (3a).
Receives current from f). Since the slip ring (6f) is used as in the conventional case, the general-purpose brush (5e) is worn due to a large amount of friction, which is unavoidable.

Since the U-phase, V-phase and W-phase of the induction armature (3) serve as electromagnets for each magnetic flux (8d), if an alternating current is applied to this,
A rotating magnetic field is created. The permanent magnet (4f) of the rotor (4) is guided by the rotating magnetic field of the induction armature (3) so that the rotor (4) rotates in the direction in which the rotating magnetic field rotates.

As a result, the magnetic poles (8d) made up of the permanent magnets (4f) of the large number of induction armatures (3) and the large number of rotors (4) are alternately sandwiched, and the reaction force is generated by receiving the electric energy. And the rotor vane (3a) provided in the induction armature (3) and the rotor vane (4a) provided in the rotor (4) also rotate in reverse. However, the synchronous motor is started using an inverter, and the start is gradually increased from 2 cycles or less so as not to get out of sync.

According to a twelfth aspect of the present invention, in the contra-rotating axial-flow electric compressor, the contra-rotating power feeding device for the counter-rotating type is provided in the casing (1) through the bearing (2) and the shaft (3a) of the induction armature (3). Rotatably attached. And, to the power feeding device, the cover (5c) is attached to the casing (1), and the cover (5c) is attached.
Has a point (5) from the electric cord (5d) through the electric terminal (5d). At this time, since the cover (5c) is small and light, even if the point (5) of the protrusion is designed small, it is not damaged.

It is the induction armature (3) that receives the current.
The carbon (6) of the shaft (3a) is pushed by the spring (6e), receives the current at the point (5), and is fed to the power supply terminal (6).
Although passing through the internal code (6c) from (a), since the carbon (6) has the point (5) at the center of the shaft (3a), it has little friction and hardly wears. To explain this by using the top as an example, the top of the top is in contact with the center point, so there is little friction, so if you press the outside of the top, it will stop easily. The point is that there is little friction. Similarly, it receives a current from the other shaft (3a). Then, cover the other phase current (5
The general-purpose brush (5e) is attached to c), and the shaft (3a) receives an electric current from the slip ring (6f). Since the slip ring (6f) is used as in the conventional case, the general-purpose brush (5e) is worn due to a large amount of friction, which is unavoidable.

Since the U-phase, V-phase and W-phase of the induction armature (3) serve as electromagnets for each magnetic flux (8d), when an alternating current is applied to this,
A rotating magnetic field is created. The permanent magnet (4f) of the rotor (4) is guided by the rotating magnetic field of the induction armature (3) so that the rotor (4) rotates in the direction in which the rotating magnetic field rotates.

As a result, the electrodes (8d) made up of the permanent magnets (4f) of the large number of induction armatures (3) and the large number of rotors (4) are alternately sandwiched, and the reaction energy is received by receiving the electric energy. And the rotor vane (3a) provided in the induction armature (3) and the rotor vane (4a) provided in the rotor (4) also rotate in reverse. However, the synchronous motor is started using an inverter, and the start is gradually increased from 2 cycles or less so as not to get out of sync.

(I) A perspective view of FIG. 16 with a part cut away, showing the external appearance of the reverse rotation axial flow electric compressor.
A trial production of a 225 mm-diameter one having a diameter of 225 mm is described with reference to the cross-sectional view of FIG. 9. The counter-rotating axial-flow electric compressor of the three-phase induction motor type according to claim 9, wherein the casing (1) has a bearing (2). ), The shaft (3a) of the induction armature (3) is rotatably attached. A cover (5c) is attached to the casing (1) of the power feeding device, the cover (5c) is pushed from the electric cord (5d) through the electric terminal (5d), and the point (5) is pushed by the spring portion (5a). Are in contact.

It is the induction armature (3) that receives the current.
The carbon (6) of the shaft (3a) receives the electric current at the point (5) and is fed from the power supply terminal (6a) to the internal cord (6c).
However, since the carbon (6) has a point (5) at the center of the shaft (3a), it has little friction and hardly wears. Similarly, it receives current from the end of the other shaft (3a).

Then, the current of the other phase is covered (5c).
A general-purpose brush (5e) is attached to the shaft (3a), and the shaft (3a) receives a current from the slip ring (6f). Since the slip ring (6f) is used as in the conventional case, there is a lot of friction and the general-purpose brush (5e) is worn, but it cannot be helped. However, there is a rotary connector on the market, and if the rotation speed is 800 rotations / minute, the rotation speed can be sufficiently used. Further, as the diameter becomes large, the number of rotations becomes slower, and the number of rotations becomes 200 when the diameter is 1 meter.

As shown in FIG. 26, the rotor (4) is formed by punching a strip-shaped silica steel into a slot (4b) and winding it to make 26 slots (4b). First, wind the slot (4b) outside the center end link (4d), insert the copper rotor bar (4c) into the slot (4b), and finally stop the copper end ring (4d) by TIG welding. However, brazing is common in books. The intervals of the slots (4b) are on the left side, the intervals of the slots (4b) are narrow, and the intervals on the right side are the outside and the intervals of the slots (4b) are wide, as can be seen from the figure. And it is common to twist 1 slot, and about 1 slot can be made by winding silicon steel.

Since the one-slot twist may generate an abnormal torque during the start and the start may not be successful, or an abnormal vibration may be generated during the operation, this method was used. However, it is common to melt aluminum by aluminum die casting and inject it into the preheated silicon steel, and the rotor (4) and induction armature (3) thus formed are alternated. Install by sandwiching.

As a result, the large number of induction armatures (3) and the large number of rotors (4) receive electric energy and rotate in opposite directions by reaction force, and the shafts provided in the induction armature (3). The wing (3b) and the rotor wing (4a) provided on the rotor (4) also rotate in reverse. At this time, since the wind is sent by the seven-stage wing, the burden on the one-stage wing is reduced, and since the wing is not warped, reverse injection can be performed with one switch. Also,
If there is the same static pressure as the centrifugal fan and no static pressure is applied,
It does not require power consumption like a centrifugal fan.

(V) The power supply device for counter-rotating type of the three-phase induction motor type counter-rotating axial flow electric compressor according to claim 10 is installed in the casing (1) through the bearing (2) and the induction armature (3). ) Shaft (3a) is rotatably attached. Then, in the power feeding device, the cover (5c) is attached to the casing (1), and the cover (5c) has a point (5) from the electric cord (5d) through the electric terminal (5d).

It is the induction armature (3) that receives the current.
The carbon (6) of the shaft (3a) is pushed by the spring (6e), receives the current at the point (5), and is fed to the power supply terminal (6).
Although passing through the internal code (6c) from (a), since the carbon (6) has the point (5) at the center of the shaft (3a), it has little friction and hardly wears. Similarly, it receives current from the end of the other shaft (3a).

Then, cover another phase current (5c).
A general-purpose brush (5e) is attached to the shaft (3a), and the shaft (3a) receives a current from the slip ring (6f). Since the slip ring (6f) is used as in the conventional case, the general-purpose brush (5e) is worn due to a large amount of friction, which is unavoidable.

As for the rotor (4), as shown in FIG. 26, strip-shaped silica crude steel is punched and wound into slots (4b) to form 26 slots (4b), and a perspective view of a part of FIG. 27 is cut out. First, wind the slot (4b) outside the center end link (4d), insert the copper rotor bar (4c) into the slot (4b), and finally stop the copper end ring (4d) by TIG welding. However, brazing is common in books. The intervals of the slots (4b) are on the left side, the intervals of the slots (4b) are narrow, and the intervals on the right side are the outside and the intervals of the slots (4b) are wide, as can be seen from the figure. And it is common to twist 1 slot, and about 1 slot can be made by winding silicon steel.

This method was used for the one-slot twisting because abnormal torque may be generated during starting and the starting may not be successful, or abnormal vibration may be generated during operation. However, it is common to melt aluminum by aluminum die casting and inject it into the preheated silicon steel, and the rotor (4) and induction armature (3) thus formed are alternated. Install by sandwiching.

As a result, the large number of induction armatures (3) and the large number of rotors (4) receive electric energy and rotate in opposite directions by the reaction force, and the shafts provided in the induction armature (3). The wing (3b) and the rotor wing (4a) provided on the rotor (4) also rotate in reverse. At this time, since the wind is sent by the seven-stage wing, the burden on the one-stage wing is reduced, and since the wing is not warped, reverse injection can be performed with one switch. Also,
If there is the same static pressure as the centrifugal fan and no static pressure is applied,
It does not require power consumption like a centrifugal fan.

By the way, static pressure pushes away 52 mm of water. At this time, since the wind is sent by the seven-stage wing, the burden on the one-stage wing is reduced, and since the wing is not warped, reverse injection can be performed with one switch. Further, when the static pressure is the same as that of the centrifugal fan and no static pressure is applied, power consumption is not required unlike the centrifugal fan.

It is the induction armature (3) that receives the current.
The carbon (6) of the shaft (3a) is pushed by the spring (6e), receives the current at the point (5), and is fed to the power supply terminal (6).
Although passing through the internal code (6c) from (a), since the carbon (6) has the point (5) at the center of the shaft (3a), it has little friction and hardly wears. Similarly, it receives a current from the other shaft (3a).

As described above, the present invention has the following effects in the power supply device for counter-inversion type. (B) By attaching the brush to the casing toward the point and to the center of the shaft of the induction armature, the thickness was thinned so that it could be used for a ventilation fan. (B) Since power is supplied at the point, the brush does not bald unlike the slip ring, so maintenance is not required. (C) When designing a motor of the same capacity, the outer rotor type induction motor is efficient when the induction armature is arranged inside because the diameter of the gap surface becomes large. (D) The coil is easily wound by disposing the induction armature inside. (E) By arranging the induction armature on the inside, the coil can be made about half shorter than when it is wound on the outside, so that the electric resistance of the coil is small.

The counter-rotating fan that is a use example of the present invention has the following effects. (A) Since the wind from the fan is jetted straight, the wind can reach even 10 meters away. (B) Since the rotation is halved, the wind noise of the wings is quiet, but the amount of air sent is not inferior. (C) The double-reversal electric motor consumes less power. (D) In the case of a ventilation fan, etc., the main body of the motor can be removed, so cleaning of the wings is easy. (E) In the case of a three-phase reverse rotation axial flow electric compressor, since warping is not required, reverse injection can be performed simply by changing the wiring.
