STATOR STRUCTURE OF FREE MAGNET TYPE INDUCTION MOTOR

摘要

A stator structure of a rotational magnetic type induction motor is provided to form teeth of a stator where a main coil and a sub coil are wound in inequality pitch type so that pitches wound by the main coil can be large, thereby improving a driving efficiency by increasing a counter electromotive force. A stator(102) is configured, wherein plural teeth(105) are protruded in central direction while a main coil and a sub coil are wound on the teeth(105) in turns. The teeth(105,105') are formed in inequality pitches, so that the teeth(105) wound by the main coil are at the angle of 36 degrees on a center while the teeth(105') wound by the sub coil are at the angle of 24 degrees. A relatively larger counter electromotive force is generated from the mail coil than the sub coil.
