PURPOSE:To make a motor speed control circuit stabilize the rise of a motor used for such OA equipment, as a copying machine, printer, facsimile, etc., at the time of actuating the motor at a high speed. CONSTITUTION:In a motor speed control circuit, a latch circuit 33, full-torque circuit 34, and charge circuit 35 are incorporated so that the control circuit can quickly stabilize the rise of a motor for rotation by simultaneously impressing a full torque and charging a capacitor for control. |
