PURPOSE:To stop a motor in the prescribed phase with an inexpensive construction by rotating the motor to the prescribed phase in the prescribed direction in response to the rotary phases and the rotating direction detected when the stopping operation is designated. CONSTITUTION:A designation signal transmitted from a switch 3 as designation means for designating the rotating or stopping operation of a motor 1 is input to a control electronic circuit 2, and when a designation signal for designating the stopping operation from the switch 3 is input, the circuit 2 controls motor drive transistors 6-9 on the basis of the outputs from sensors 4, 5 for detecting the rotary phase and the rotating operation of the motor 1 to stop the motor 1 in the prescribed phase. |
