Document Type and Number:
WIPO Patent Application WO/2008/111775
Kind Code:
A3
Abstract:
An electric motor is disclosed. The motor in which a rotor (120) is started using induction torque generated as power is supplied to a coil (112, 114) of a stator, the rotor (120) includes a rotor core (123), conductive bars (122) arranged along a circumferential direction, in an outer rim region of the rotor core (120), to generate an induction current, flux barriers (140) formed in the rotor core (120), to interrupt flow of a magnetic flux, for generation of reluctance torque, and magnets (130) provided in the rotor core, to generate a magnetic flux, for generation of magnetic torque.
