    • An exciting coil of a motor is formed to be controlled by using an analog timer, to thus control an excitation control circuit of a motor control apparatus, whereby an excitation control circuit which excites the exciting coil of a motor control apparatus can be simplified and complexity can be reduced by simplifying a circuit construction of an excitation controller. The apparatus includes an auxiliary winding (sub-coil) and a main winding (main coil), and an exciting device electrically connected with the auxiliary winding and the main winding, determines an excitation application time and an excitation time and generates an excitation current according to the determined excitation application time and the excitation time.

    • 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.
    • 自励电动机和具有该自励磁电动机的压缩机被配置为需要较低的启动电压并提供优异的性能。 在自励电动机中,当向定子的磁化单元供电时,转子的外部的磁性材料被磁化。 多个导电棒插入转子芯的外圆周上。 导电棒的外部部分和可磁化材料的内周之间的间隔距离比定子和转子之间的气隙长。 结果,可以增加磁性材料的磁强度。
