Embodiment Construction
[0048] Such as figure 1 , a stator permanent magnet type dual-rotor magnetic field modulation motor of the present invention and a design method thereof, the motor includes an inner rotor 1, a stator 2 and an outer rotor 4 in sequence from the inside to the outside, between the inner rotor 1 and the stator 2, between the stator 2 and the Outer rotors 4 all leave air gaps. Each yoke of the stator 2 is embedded with a radial permanent magnet 3, which adopts tangential excitation, and the N poles and S poles of the radial permanent magnets 3 are arranged alternately along the circumference; the stator outer teeth 8, the stator inner teeth 9 It is a straight tooth structure, the inner winding 5 and the outer winding 6 are arranged in the slot of the stator 2, and the inner rotor 1 and the outer rotor 4 are both outer rotor teeth 7 and inner rotor teeth 10 of a salient pole tooth structure formed by lamination of silicon steel sheets. . In addition, the number of pole pairs of pe...
