<p>A motor is disclosed. A motor according to the present invention includes: a stator including a plurality of teeth that forms a plurality of slots, a through hole formed in the center by the tips of the plurality of teeth, and a coil that is wound around the teeth and generates rotating magnetic field by applying electricity; a rotator that is rotatably inserted in the through hole and has an axle hole into which a rotating axle is inserted and a plurality of permanent magnets disposed around the axle hole; and a hysteresis band that is disposed on an outer periphery of the rotator. According to the present invention, since the hysteresis band is disposed on the outer periphery of the rotator, the motor can overcome the braking torque by the permanent magnets in transition state and starts normally and generates magnetic flux in normal operation with synchronous speed, thus increasing the efficiency of the motor.</p> |
