SELF MAGNETIZING MOTOR AND METHOD FOR WINDING MAIN COILS AND SUB COILS ON STATOR THEREOF

摘要

A self magnetizing motor and a method for winding main coils and sub coils on a stator thereof are provided to increase efficiency thereof by revolving the stator with a synchronous speed of magnetic field without a slip of the stator and effectively prevent a noise caused by a vibration. In a self magnetizing motor, a stator(110) includes a plurality of stator slots(111) and exciter slots(112) which are formed on an inner circumference thereof with a regular gap, wherein teeth(113) are formed between the stator slots(111), an exciter pole(114) is formed between the exciter slots(114), and an end portion of the exciter pole(114) is arranged to be more adjacent to a central portion than an end portion of the teeth(113). A main winding is wound on the stator slots(111). A sub winding is wound on the stator slots(111) to have a current phase preceeding 90 degrees than the main winding. An exciter coil is wound on the exciter slots(112). A rotator(160) installed on the central portion of the stator(110) has an exciter magnetizing portion(150) on an outer circumference thereof for being magnetized by the exciter coil.
