WOUND ROTOR BRUSHLESS DOUBLY-FED MOTOR

摘要

The invention disclose a type of winding rotator brushless double feed motor. This invention falls into motor technology field. The AC brushless double feed motor's rotator is equipped with two sets of three phase windings whose number of pole pairs is p1 and p2; the rotator is in manner of multiphase winding, number of pole pairs is P1 and P2, and rotator is of multiphase coil windings, number of phases m is: m = ( p 1 + p 2 ) / m k in which , m k =1, when p 1 + p 2 is odd; ; m k =2, when p 1 + p 2 is even, , rotor slots are distributed around air gaps, the number of slots Z ' is : Z ' = n ( p 1 + p 2 ) in which , n is a positive integer , coil of rotator windings is in structure of multi turn, number of coils of each phase is nm k , distance between each coil is even, but the number of turns of each coil is different, when number of phase winding coils is ‰¤ nm k , all coils of phase windings will be short circuit connected after then are connected in series. The advantage of this invention lies in that, not only span of winding coils can be changed flexibly, the number of turns of each coil is different, in order to remove higher-order harmonics as possibly as.
