摘要
A single phase induction motor and a compressor utilizing the single phase induction motor wherein the motor has a stator having a plurality of slots; a rotor being rotated by a magnetic field generated by an electric force between the stator and the rotor; and a main winding and a sub winding wound through the plurality of slots of the stator to form a revolving magnetic field of the rotor. The main winding and the sub winding form a centralized type of winding structure so that the main winding and the sub winding are wound in an alternate pattern via adjacent slots. Since the centralized winding structure of the main winding and the sub winding which are wound through the slots of the stator, the coil end is greatly reduced, and as a result, the material costs and copper loss can be greatly reduced. Further, the main winding and the sub winding, which are wound through the slots of the stator, do not protrude from opposite sides of the stator too much. Accordingly, processes like forming, lacing and cleaning for tidying up the protruded portion of the main winding and the sub winding, can be omitted, thereby simplifying the manufacturing process.
