ABSTRACT:
An induction motor as driving apparatus includes two stators in which two rotor cores each formed in a squirrel cage type are rotatably mounted on a common rotary axis; two stators which respectively surround the two rotors and on which stator windings are respectively wound; and a switching device which supplies power by sequentially switching between one side of either the one stator winding or the other stator winding and both the sides of the two stator windings. Starting characteristics and operation characteristics of an induction motor are improved thereby enlarging applications of the induction motor, enhancing operation efficiency, and reducing power consumption.
