Japanese Patent JP2786729
Kind Code:
B2
Abstract:
A clothes washing machine includes an agitator driven for agitating clothes to be washed, a dc brushless motor for driving the agitator and a microcomputer-based control device. A voltage applied to the motor can be varied in accordance with a voltage value command delivered from the control device. The number of revolution of the motor is detected and compared with a reference number of revolution for determination of whether the motor is locked or not. When the control device sequentially detects at a predetermined number of times that the number of revolution of the motor is equal to or below the reference number of revolution or below, it is determined that the motor is locked.
