Example Embodiment
[0022] Such as figure 2 As shown, the present invention includes two main parts: the stator 1 and the rotor 2. The stator 1 has the same structure as the stator of an ordinary AC motor. The stator core 11 is laminated by slotted silicon steel sheets and the number of phases embedded in the core slot is m 1 , The stator windings 12 whose pole pairs are P are composed together. The structure of the rotor 2 is similar to that of a common salient-pole synchronous motor, and the number of salient poles on the rotor 2 is n p , N p The convex magnetic poles 21 are evenly distributed on the circumference of the back yoke 22, and the AC coil 23 is sleeved on the convex magnetic pole 21, but the damping winding in the conventional synchronous motor rotor is eliminated on the rotor magnetic pole.
[0023] The number of salient poles on the salient pole rotor n p Satisfy:
[0024] 2Pp <4P (1)
[0025] That is, the number of salient poles n p More than the number of poles in the magnetic fiel...
