Abstract:
A self magnetizing motor and a compressor having the same is configured to require a lower starting voltage and to deliver superior performance. In the self magnetizing motor, a magnetic material on an exterior of the rotor is magnetized when power is supplied to a magnetizing unit of the stator. A plurality of conductive bars are inserted on the outer circumference of the rotor core. A spacing distance between outer portions of the conductive bars and inner circumference of the magnetizable material is longer than an air gap between the stator and the rotor. As a result, a magnetic strength of the magnetic material may be increased.
