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.
A method for supplying power to an induction motor having a first power generation means constituted by a first rotor and a first stator which surrounds said first rotor and on which a first stator winding is wound and a second power generation means constituted by a second rotor and a second stator which surrounds said second rotor and on which a second stator winding is wound, said first and second power generation means being connected to a common load, said method comprising the following sequential steps:
