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, magnets (130) provided in the rotor core (120), to generate a magnetic flux, for generation of a magnetic torque, and end-rings (150, 151 ) provided at the top and bottom of the rotor core (120) to have no interference with the magnets (130), the end-rings (150, 151 ) being connected with the plurality of conductive bars (122). Another embodiment, instead of the magnets (130), comprises flux barriers (140) formed in the rotor core (120), to interrupt flow of a magnetic flux, for generation of reluctance torque. |
