Embodiment Construction
[0038] The present invention will be further elaborated below through specific embodiments.
[0039] Such as Figure 1-6 As shown, a modular built-in hybrid permanent magnet motor rotor structure, including 3n fan-shaped rotor modules, n=2,4,6..., and the internal shaft 9-1; 3n rotor modules are composed of three rotor structures Arranged in order, the three rotor modules are provided with permanent magnet slots for embedding permanent magnets. The permanent magnet slots of the three rotor modules are V-shaped slots 2-1 facing the outer circle of the rotor and the first inverted triangular slots. 1-1 and the second inverted triangular groove 3-1, the bottoms of the inverted triangular groove 1 and the inverted triangular groove 2 are all provided with reinforcing ribs.
[0040] The above-mentioned 3n rotor modules are all made of laminated silicon steel sheets, and 3n=2p, where p is the number of pole pairs of the motor; the rotor circumference angle occupied by the 3n rotor ...
