Abstract
PURPOSE:To increase the initial driving current of the motor by adding a capacitor to a circuit wherein the rotation of the DC motor is controlled reversibly by using a transistor and by utilizing a charge current flowing through the capacitor. CONSTITUTION:When a signal is inputted in an input terminal 1, a switching transistor 3 is turned on, the by transistors 5 and 6 for driving the motor are turned on to rotate the motor 11 in the fixed direction, while at the same moment the charge current flows to the capacitor 13 to increase the base current of the transistors 5 and 6 for driving the motor, and thereby the initial driving current of the motor 11 is increased. And, when the signal is inputted in an input terminal 2, the current flows to the capacitor 14 through the same operations and the motor 11 is rotated in the reverse direction by the large initial driving current. Accordingly, by adding the capacitors 13 and 14, the starting of the motor 11 can be made smooth by the charging actions thereof.
