A controller of a compressor of the present invention sets a time in a timer according to a motor current detected by a motor current detector. When a time has reached the time set in the timer, the rotating speed of a DC motor is increased. Therefore, control of the rotating speed according to a load can be achieved. When it is determined that a refrigerator load is great, the compressor is operated at a higher speed quickly, while when it is determined that the refrigerator load is smaller, the compressor is operated at a lower speed, which results in energy saving.
