Permanent magnet field motors that use permanent magnets in the field can shorten the production process because there is no need to wind the field, and at the same time improve efficiency because there is no field copper loss. It is widely used because of its advantages. However, permanent magnets have the problem of demagnetization.
Another drawback is that it is difficult to obtain a high magnetic flux density compared to a normal wire-wound field. For this reason, there is Japanese Patent Publication No. 48-35721 in which an auxiliary pole made of a magnetic material is provided at the end of the field that acts to increase the magnetization of the armature reaction magnetomotive force. Tokko Akira
Figure 1 shows the stator structure of the two-pole machine of No. 48-35721. In FIG. 1, the permanent magnet 8 is arranged on the inner peripheral surface of the cylindrical yoke 7, and faces the armature core 3 with a suitable gap in between. Auxiliary pole 9 made of magnetic material
Similar to the permanent magnet 8, the armature core 3 faces the armature core 3 with a suitable gap therebetween, and is arranged in parallel with the permanent magnet 8 with a circumferential gap W provided therebetween.

ルクは(2)式に示すように比例する関係にある。 In the electric motor constructed in this manner, the characteristics of the rotation speed and motor torque are determined by the amount of main magnetic flux generated at the field poles. That is, the rotation speed is inversely proportional to the amount of main magnetic flux as shown in equation (1), and the motor torque is proportional as shown in equation (2).

で界磁極の磁束量は、ほとんど永久磁石８で発生
する磁石量で決定される。 The magnitude of the main magnetic flux generated at the field poles of the permanent magnet field motor with auxiliary poles in FIG. 1 is shown by the broken line in FIG. 6. As the armature current increases, the amount of magnetic flux ΦM of the permanent magnet gradually decreases due to the increase in the demagnetizing field of the armature reaction.
On the other hand, the amount of magnetic flux ΦA from the auxiliary pole increases as the armature current increases due to the increased magnetic field of armature reaction. The main magnetic flux amount Φ of the field pole in FIG. 6 is the sum of the magnetic flux amount ΦM of the permanent magnet and the magnetic flux amount ΦA of the auxiliary pole. FIG. 2 shows a magnetic flux distribution diagram of the field pole at point N shown in FIG. 6, that is, at a light load with a small armature current. At point N, where the armature current is small, the magnetizing effect and demagnetizing effect due to armature reaction are small, and there is no magnetic flux leaking, so the amount of magnetic flux at the field pole is almost determined by the amount of magnet generated by the permanent magnet 8.

で、大きなトルクが得られる。 The broken line in FIG. 7 shows the characteristics of the motor rotation speed and motor torque with respect to the armature current of the one shown in FIG.
Generally, in a starter motor for starting an engine, when there is an overload at point K shown in Fig. 7, that is, when starting,
Large motor torque is required. Furthermore, once the engine starts, the starter motor is almost in a no-load state and is at the N point. The rotational speed of the starter motor at this point N must be higher than the engine rotational speed (the rotational speed including the conversion by the gear). However, as shown by the broken line in FIG. 7, the motor rotational speed at point N in FIG. 1 is low due to the large amount of main magnetic flux generated at the field poles. As a result, the starter motor became a load on the engine, causing problems. On the other hand, the motor torque at startup in Figure 1 is
As shown in FIG. 7, since the amount of main magnetic flux of the field pole is large, a large torque can be obtained.

The present invention provides an anisotropic permanent magnet field disposed on the inner circumferential surface of a yoke, and a permanent magnet field as a means for ensuring the amount of magnetic flux at startup and reducing the amount of magnetic flux only during light loads.

The outer periphery is located on the radiation line away from the permanent magnet field, and at least a part of the joint of the auxiliary pole intersects with the magnetic flux direction of the permanent magnet field. By doing so, a field pole with a large amount of main magnetic flux at startup and a small amount of main magnetic flux at light load can be obtained. Therefore, a permanent magnet field motor with a large motor torque at startup and a high rotational speed during light loads can be obtained.

Ａの傾斜面に全面的に接合して並設されている。 In the permanent magnet field motor with auxiliary poles constructed in this manner, the main magnetic flux is supplied from the permanent magnet 8 during light loads where the armature current is small, but when the rated or overloaded armature current is large, the armature reaction magnetic flux Therefore, the main magnetic flux is increased through the auxiliary pole 9'. FIG. 4 shows an example of a stator structure that reduces the amount of main magnetic flux during light loads.
In FIG. 4, field poles 8 and 9' arranged on the inner peripheral surface of an annular yoke 7 are composed of a permanent magnet 8 and an auxiliary pole 9' made of a magnetic material (iron).
The outer peripheral side of the permanent magnet 8 in the circumferential direction is located so as to protrude from the center a-a' line of the magnetic poles of the field poles 8 and 9' toward the increasing field side of the armature reaction, and is located on the side of the increasing field of the armature reaction.

に軽負荷時の回転数は高くなる。 Here, the inner circumferential end 9B of the auxiliary end face 9A is positioned so as to be retreated from the radiation direction O-R toward the opposite permanent magnet side,
The junction of the auxiliary pole 9' is arranged to intersect the direction of the magnetic flux of the permanent magnet 8. That is, the feature of the present invention is that a part of the auxiliary pole made of a magnetic material is inserted into the end of the permanent magnet 8. That is, the auxiliary end face on the side adjacent to the permanent magnet has an inner periphery located on the radiation line and an outer periphery set back from above the radiation line toward the side opposite to the permanent magnet, and at least one of the joint parts of the auxiliary pole The magnetic flux direction of the permanent magnet is made to intersect with the magnetic flux direction of the permanent magnet. In this way, permanent magnet 8
By making the auxiliary pole bite into the end in the magnetization direction, the amount of magnetic flux during light loads is reduced. FIG. 5 shows the magnetic flux distribution diagram at light load in FIG. 4. As shown in FIG. 5, in the case of the present invention, when the load is light, a part of the magnetic flux of the permanent magnet 8 juxtaposed with the auxiliary pole 9' passes through the biting part of the auxiliary pole 9' made of magnetic material to the armature core. A magnetic flux 10 is generated that lubes without reaching . Therefore, as shown in FIG. 6, the amount of magnetic flux ΦM of the permanent magnet 8 during light load is reduced as shown by the solid line. Therefore, the magnetic flux amount Φ of the field pole is the sum of the magnetic flux amount ΦM of the permanent magnet and the magnetic flux amount ΦA of the auxiliary pole.
, as shown by the solid line, is smaller than the conventional one shown in FIG. 1, shown by the broken line. Therefore, as shown in FIG. 7, the rotational speed becomes high when the load is light.

For this reason,
The amount of main magnetic flux of the field pole at startup is different from the conventional first magnetic flux.
As in the figure, large values are obtained. Therefore, a large motor torque can be obtained.

Even if the cavity 11 is provided, the effect is the same. Further, as shown in FIG. 9, the present invention may also be applied if the end face 9A of the auxiliary pole 9' is made into an L-shape, and the inner terminal end 9B of the tip part 12 is bitten into the radiation line O-R and joined to the permanent magnet 8. Shows similar effects.

According to the present invention, the auxiliary end face on the side adjacent to the permanent magnet is arranged so that the inner circumference is located on the radiation line and the outer circumference is located on the radiation line away from the side opposite to the permanent magnet field. By making the auxiliary pole bite into a part of the magnet, a magnetic flux is generated that loops between the permanent magnet and the auxiliary pole without reaching the armature core when the motor is under light load, so the amount of main magnetic flux of the field pole decreases. Therefore, it is possible to reduce the amount of main magnetic flux only during light loads while ensuring the motor torque at the time of startup, so it is possible to provide a permanent magnet field motor that can increase the motor rotation speed during light loads.
