Abstract

PURPOSE: To obtain a high performance motor having an excellent power efficiency by using a switching-type voltage converter which is capable of taking out a variable-output DC voltage, and controlling the voltage-converter output so as to keep the transistor-operating voltage at a specified value.
CONSTITUTION: An output voltage Vc of a voltage converter 6 takes a value corresponding to the duty period of the on-time of a transistor 20. Said output voltage Vc enters into a controlling transistor 7a which is connected to the feeding part to a conduction-switching device 9 in series, and an output voltage Ve is supplied to a motor portion 10 depending on a commanding signal 12 by way of the conduction-switching device 9. Then, the operating voltage (Vc-Ve) of the control transistor 7a is detected by a differential transistors 33 and 34 which constitute an operation detector 8. When the operating voltage is lower than a specified value, a switching control device 26 turns a transistor 22 on by the turn-on of the transistor 34, and makes the output voltage Vc of the voltage converter 6 high. If the operating voltage is high, the output voltage vc is made low.
