Problems solved by technology

According to the knowledge of the inventor, most current multi-phase motors have the problems of magnetic flux leakage at the end and low utilization rate of the motor iron core material. The outer part of the rotor is the outer stator. The heat generated by the motor is concentrated in the axial direction of the motor. The thermal load of the motor is very high, and the inner stator is not connected to the external environment. It is difficult for the motor to dissipate heat.

Embodiment 1

[0081] As shown in Figure 1(a)-Figure 1(e), the number of motor phases in this embodiment is 6, the number of radial stator teeth is 48, the number of axial stator teeth is 48, the number of rotor slots is 8, and the number of radial magnetic poles is 8 , the number of axial magnetic poles is 8, one end of the rotor has a fan ring structure, and a permanent magnet is attached to the fan ring, and the polarity generated by the permanent magnet on the fan ring on the iron core side is the same as that generated by the permanent magnet in the rotor slot The polarity of the axial magnetic flux is the same. This embodiment includes a radial stator, an axial stator and a rotor. The radial stator is made of laminated silicon steel sheets. The radial stator includes radial stator teeth 1, radial stator yoke 2 and radial To the stator slot 3, radial armature windings 4 are placed in the radial stator slots 3. The radial armature windings 4 can be divided into distributed windings, conce...

Embodiment 2

[0083] As shown in Figure 2(a)-Figure 2(e), the main difference between Embodiment 2 and Embodiment 1 is that (1) there are axial stators at both ends of the motor in Embodiment 2, and the motor has soft magnetic The two ends of the composite rotor core are processed into the shape of the fan ring to form the axial magnetic poles, but in the first embodiment, only one end of the motor has an axial stator, and only one end of the motor rotor core is processed into a fan ring. The shape forms the axial magnetic pole. (2) In the second embodiment, because the two sections of the rotor are all processed into the shape of the fan ring, the number of permanent magnets that need to be surface-mounted on the fan ring increases. The structure in the second embodiment, because the two ends of the rotor Both have rotors that eliminate unbalanced magnetic pull on the rotors. In this embodiment, the number of motor phases is 6, the number of radial stator teeth is 48, the number of axial s...

Abstract

At least one end of that rotor is provide with an axial stator, and the axial stator is concentrically arranged with the rotor; The stator slot of the radial stator is provided with a radial winding,The axial stator is divided into a radial stator and an axial stator, and the axial stator is arranged at the end of the rotor, so that the magnetic leakage effect at the end of the motor can be reduced, the heat dissipation efficiency can be improved, and the power density of the motor is increased by sticking a permanent magnet on the end of the rotor, so that the multi-phase control is easy torealize.
