ABSTRACT:
An improvement in the stator structure of a synchronous motor wherein flux generated by a winding produces a magnetic field in the stator structure which in turn causes a rotor to rotate. The stator structure consists of two sets of stator poles intermeshed together. Shading base associated with certain of the stator poles insures that the rotor will start to rotate in a predetermined direction. The running characteristics of the synchronous motor are improved by having one of the sets of stator poles constructed of three different widths and the other set constructed of two different widths. The improved stator structure provides for equal flux distribution within the stator poles causing the motor to run smoothly.
