Description of the Related Art In recent years, as the performance of permanent magnets has improved, the chances of using the permanent magnets as a rotor or rotor of a generator / motor have increased. In addition, a power generator / motor using a permanent magnet as a rotor has recently come to be widely used in industrial equipment because of its high power generation efficiency or electric efficiency and its simple structure.
Therefore, the development of technologies for downsizing power generators and electric motors, as well as for higher performance and higher output, has become popular, and along with this, it is necessary to diversify the components.

電圧をかけずに電動機を回転させることができる。By the way, in the permanent magnet type generator / motor,
Since the magnetic force of the permanent magnet does not change, it is difficult to change the generated voltage or suppress the torque of the electric motor. In the generator, the generated voltage increases proportionally as the rotation speed increases. The reason is that the voltage of the generator is determined by the product of the frequency, the magnetic flux and the number of windings, so the rotation speed of the rotor is a variation function, and the others are constants, so the voltage rises as the rotation speed increases. It will be. This can be expressed by the following formula. U = 4.44 × f × φ × W × KW 1 where f: frequency, φ: magnetic flux force, W: number of windings, KW 1 :
Winding factor As shown in the above equation, in the permanent magnet generator / motor, in order to keep the voltage constant when the generator is operating,
A device such as a complicated switching regulator that divides the current of the generated power cannot be used alone. Also, when operating a permanent magnet power generator / motor,
The counter electromotive force acts as the number of revolutions increases, and the voltage of the electric power that is applied against this electric power rises, and the characteristics of the motor are lost. That is, since a generated current flows through the winding, it cannot operate as an electric motor unless a high-voltage current flows against this current. At this time, if the magnetic flux density is small, the counter electromotive force is small, so that the electric motor can be rotated without applying a too large voltage.

In particular, for electric vehicles whose rotation speed fluctuates, such as electric vehicles, which are expected to develop in the future, the above-mentioned increase in magnetic flux density leads to an extremely significant performance improvement in order to improve the efficiency and torque of the electric motor and increase the rotation speed. Connect. To satisfy the above,
It is effective to put a resistor in the magnetic path of the permanent magnet to reduce the magnetic force, but this magnetic force control is impossible with the ordinary method. The most effective way to reduce the magnetic force is to provide an air layer in the magnetic path.

In the permanent magnet power generator / motor, the cylindrical member is formed into a cylindrical shape as a whole by alternately laminating magnetically permeable members having a rectangular cross section and non-magnetically permeable members arranged between the magnetically permeable members. The chamfer portions are formed at both corners of the member, the chamfer portions are formed at both corners of the comb portion of the stator, and a predetermined amount of clearance is formed between the chamfer portions. Since the comb portion has a rectangular shape and the chamfer portion is formed at the corner portion, when the cylindrical member starts to rotate slightly, the gap between the comb portion and the magnetically permeable member overlaps for a long period of time. The amount of clearance between the two is almost unchanged, and the magnetic flux cannot be controlled.

ーをしなければならず，不具合が発生することになる。Regarding the structure of the generator / motor, it is demanded that the external shape of the generator / motor be as small and compact as possible when it is mounted in a limited space such as an automobile. Considering the space occupancy rate for generators and motors, the windings occupy a large proportion. In particular, the winding wire of the generator / motor is wound up in the slot portion of the stator, but since the slot portion of the stator is open to the inside, it is extremely difficult to wind the winding orderly from the inside of the slot portion. The current situation is that various measures have been taken. For example, even if the winding wire is wound up in order in the slot portion that opens inside, the space factor of the winding wire in the slot portion is 50%.
It becomes the following. Therefore, the winding is wound in advance to form a bundle, and the winding bundle is fitted into the slot portion of the stator and wound up on the comb portion of the stator. The space factor increases to about 80%, but the wire of the winding sticks out from both ends of the stator,
This causes an increase in the axial length of the stator. In addition, the winding that extends beyond the end portion causes an increase in copper loss, and a net or the like must be covered for the protruding end portion of the winding, which causes a problem.

くできない状態である。In order to solve the problem of manufacturing the stator as described above, in the conventional generator / motor, the members forming the comb portion of the stator are arranged side by side, and the wire rod is wound up in the comb groove of the stator core, and then the stator member is formed. There is a known method of forming a cylinder into a cylindrical shape. However, this method causes a problem in forming the core material of the stator by dividing the core material or forming a wedge-shaped cut in the core material. In a generator / motor, a sine wave is produced by the concentrated winding method or the distributed winding method in which the windings are overlapped and wound so as to straddle the comb portion of each stator.
Since the connecting portion is present, the distributed winding other than the concentrated winding cannot overlap each other at the connecting portion, so that the shunt winding cannot be performed at all.

It is possible to control the passing magnetic flux and generate a predetermined constant voltage, which is
Since the clearance amount is controlled between slopes, the clearance amount at the abutment continuously and linearly increases from the contact state immediately after the magnetic flux control ring starts oscillating movement.
The magnetic flux flowing through the stator can be continuously and linearly controlled, and accurate and appropriate voltage control can be achieved.

ましい。Further, in order to perform the magnetic flux control efficiently by the magnetic flux control ring, it is better that the width of the comb portion of the magnetic flux control ring is smaller and the magnetic flux resistance is smaller. Therefore, the magnetic flux control ring is made of a permalloy material having a large relative permeability. Forming with a thin plate is effective. By the way, PB permalloy (47Ni-F
The relative magnetic permeability of e) is 50,000 as compared with 7,000 of 3% silicon steel, and PC permalloy (79Ni-
4Mo-Fe) is extremely large at 500000. Therefore, PB permalloy has a magnetic permeability of 7.1 times that of the silicon steel plate forming the stator core forming the comb portion, and PC permalloy has a magnetic permeability of about 71 times. The width of the magnetically permeable body of the magnetic flux control ring can be made small, and considering the effect of leakage flux and the like, about 80% of the width of the comb portion of the stator core is sufficient. In this case, in order to effectively catch the magnetic force generated from the permanent magnet and cause the magnetic force to flow to the comb portion of the stator, it is necessary to increase the width of the magnetically permeable body of the magnetic flux control ring on the rotor side. Further, it is preferable that the rotor side portion of the magnetically permeable body is formed in a shape that expands in the circumferential direction.

させることが有効である。When the rotor of the permanent magnet generator / motor is rotating in such a state, the amount of power generation is insufficient at low speeds, so that the flow passage of magnetic flux cannot be suppressed by keeping the joints in close contact and at high speeds. The amount of power generation is reduced by increasing the clearance at the joint and suppressing the amount of flux passing through the stator. As described above, the generated voltage is U = 4.44 × f × φ × W × KW by controlling the magnetic flux by moving the magnetic flux control ring.
If the product of the magnetic flux and the rotation speed is controlled to a constant value in consideration of 1 , it is possible to always obtain a constant power generation voltage that is predetermined. By the way, the magnetic permeability of air is 4π × 1
0 −7 , the relative permeability of the iron material is 6000 times, so it is effective to increase the size of the air gap in order to increase the resistance in the magnetic path.

アップすることができる。This permanent magnet type generator / motor is a device for moving and controlling a magnetic flux control ring by an actuator.
Since no conventional electrical control method is used, output loss, heat generation phenomenon, and radio interference due to high harmonic voltage do not occur, and magnetic flux control can be performed efficiently. Further, by providing a chamfered portion in the magnetically permeable body that constitutes the magnetic flux control ring, the clearance between the magnetic flux control ring and the comb portion of the stator can be reduced to about 0.05 to 0.1 mm. Since the clearance between the rotor and the rotor can be reduced to about 0.5 to 1 mm, the magnetic path loss can be significantly reduced. Further, since the clearance amount between the magnetic flux control ring and the rotor can be minimized, the efficiency can be similarly improved.
