Abstract
PURPOSE:To obtain an efficient control circuit by supplying power to a bridge circuit including an armature in one side thereof by way of a transistor and an inductance while a reverse electromotive force of the inductance is transferred to the bridge circuit. CONSTITUTION:A bridge circuit 1 is made up of resistances 2-4 and an armature 5 and connected to a power source 6 by way of an inductance 8 and a controlling transistor 7 while a switching transistors 18 and 20 are provided at respective ends of the inductance 8. Transistors 12 and 15 are controlled with a detection transistor 10 to turn on or off the transistor 7 thereby controlling the speed. When the transistor 7 is turned ON with an increase in the revolutions, a reverse electromotive force can be transferred to the bridge circuit 1 by turning ON the transistors 18 and 20 thereby enabling efficient control with a limited current consumption.
