Patent ID: 8067873

Claim:
A motor, in which a rotor is started using induction torque generated as power is supplied to a coil of a stator, wherein the rotor comprises: a rotor core; conductive bars arranged, along a circumferential direction, in an outer rim region of the rotor core, to generate an induction current; flux barriers formed in the rotor core, to interrupt flow of a magnetic flux, for generation of reluctance torque, wherein the flux barriers are arranged to provide the rotor with poles, and wherein the flux barriers that constitute each pole are arranged in two or more layers; and magnets provided in the rotor core, to generate a magnetic flux, for generation of magnetic torque, wherein a radial width of the conductive bars that are arranged within an angle defined between the center of the rotor and both ends of an outermost flux barrier is smaller than a radial width of other conductive bars.
