Abstract
A self-starting, high running torque, synchronous motor is disclosed. The motor has an annular stator and a cylindrical rotor mounted within and spaced from the inner cylindrical periphery of the stator. The rotor is provided with a plurality of evenly spaced rotor poles about its cylindrical periphery. Spaced, axially tapered poles are provided about the inner periphery of the stator. One stator pole is angularly and circumferentially offset to serve as a starting pole, while the remaining stator poles are evenly spaced about an arc which does not include the offset pole.
Claims5
A synchronous motor comprising an annular stator having a cylindrical inner periphery, a cylindrical rotor mounted within and spaced from an inner cylindrical periphery of the stator, said rotor having a plurality of rotor poles spaced about its cylindrical periphery, said stator having a plurality of stator poles spaced about its inner periphery, one of said pluralities having axially tapered poles with one of said tapered poles being angularly and circumferentially offset from the remaining poles of said one of said pluralities, said remaining poles being equally spaced from each other about an arc which does not include the offset pole.
