Abstract

PURPOSE:To efficiently drive a semiconductor motor without vibration by inputting the cyclic output of the prescribed period from a ring counter to an armature current distributor, and energizing the prescribed armature coil by the output. CONSTITUTION:When an electric switch 7a is closed, a capacitor 26a is charged through a resistor, and as the voltage rises, the base current of a transistor 25b is gradually increased, and the base current of a transistor 25a is gradually increased. When the capacitor 26b is charged to the set voltage, a trigger diode 27 is conducted, an output electric pulse is inputted to a ring counter 40, and the positive voltage is outputted to the output terminal 40a. Then, positive voltage is outputted sequentially cyclically to the output terminals 40b, 40c,... of the counter 40, and as the charging of the capacitor 26 is advanced at this time, the switching of the outputs of the output terminals 40a, 40b,... is accelerated. These outputs are applied to an armature current distributor.
