Abstract
Two magnetic poles of a permanent magnet of a permanent magnet switch and the two ends of an iron core wound with an excitation coil are connected to each other with the soft magnet having a salient pole. A motor uses the switch as the basic component of the stator and rotor, with two magnetic salient poles of each component being arranged axially, wherein the salient pole of the stator component and that of the rotor component are arranged in an opposite manner with an air gap, the excitation coil of the stator component and the rotor component at the symmetric axis position is taken as a phase line to access an excitation control power supply after serial connection or parallel connection. Electric excitation is carried out on the combined motor formed by shaft connection and rotation dislocation among single motors and the stator component in a bi-phase way simultaneously.
