Abstract
With the use of three inverter circuits controlled by a single processor, the controller of the motor-driving apparatus provides a rotation drum-driving motor, a compressor-driving motor and a blow fan-driving motor with a simultaneous sinusoidal-wave control. The configuration above offers stable sinusoidal-wave drive, reducing vibration noise of the rotation drum, the compressor and the blow fan.
