Abstract

The invention provides a self magnetizing motor and a method for winding coils on a stator thereof, wherein two exciter poles are positioned at an inner circumferential surface of the stator to face each other, and an exciter magnetizable portion is disposed at an outer circumferential surface of a rotor to thus be selectively magnetized by the exciter poles, whereby the self magnetizing motor can be operated by an induced electromotive force generated by a main coil, a sub coil and a conductive bar of a rotor from its initial driving to a speed prior to a synchronous speed, and operated by amagnetomotive force generated by the exciter poles and the exciter magnetizable portion at the synchronous speed, thereby improving an efficiency of the motor, a power factor, and a synchronization characteristic.

Description

technical field [0001] The present invention relates to a self-magnetized motor and a method for winding a coil on its stator, in particular to a motor driven by induced electromotive force and magnetomotive force and a method for winding a coil on its stator; wherein the induced electromotive force passes through the main coil , auxiliary coils, and conductive rods of the rotor are generated before initial drive to synchronous speed, and the magnetomotive force is generated by the exciter poles and the magnetizable part of the exciter at synchronous speed. Background technique [0002] In general, a motor is a device that converts electrical energy into kinetic energy, and the motor is classified into a direct current (DC) motor and an alternating current (AC) motor according to a power source to be used. [0003] AC motors include induction motors, synchronous motors and commutated motors. Induction motors can be classified into single-phase induction motors and three-pha...
