Abstract
An automatic control system for a phase angle of a motor is provided. A current detector circuit detects a current signal of the motor to output a current detected signal. A control circuit outputs a control signal according to the current detected signal indicating a time point at which the current signal reaches a zero value. A driver circuit outputs a driving signal according to the control signal. An output circuit operates to output a motor rotation adjusting signal to the motor to adjust a rotational state of the motor according to the driving signal.
