Abstract

The invention belongs to the new area of electric magnetic application. The motor consists of the abnormal shape stator and rotator, the transducer/ controller and the magnetic short path system with large and small teeth. The stator and the rotator under the electrified phase possesses equal tooth space while under the non-electrified phase possesses unequal tooth space. Controlling timely the electrifying time of the electrified phase or the current magnitude produces the magnetic resistance rotary moment. Thus, the motor will rotate under the defined speed, rotary moment and various running states of direction changing, braking, and electrical motioning or generating. The motor possesses the advantages of simple structure, easy to control and saving consumption greatly. The invention suits to use in the oil-field tube-type pump mechanical oil drawing, the water wheel generator and other technique area with low speed and large rotary moment.
