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...
