Abstract

PURPOSE:To improve the efficiency of power by a method wherein a voltage transducer according to a switching system is controlled by duty while transistors are controlled by means of a conduction controller, and winding is driven. CONSTITUTION:The output voltage of a voltage transducer 7 according to a switching system containing transistors, etc. is supplied to motor winding X, Y, Z and driving transistors 3-5. A conduction controller 2 containing a position detector of a rotor changes the conduction conditions of the transistors 3-5 in response to command signals, and controls the winding X-Z so as to make the speed of revolution of a motor constant. The currents of the winding X-Z are given to a dropped voltage generator 9 through a detector 8, are added to the signals of a speed corresponding voltage generator 10 and control the voltage transducer 7 by means of a PWM controller 12. Thus, the loss of the collectors of the driving transistors 3-5 is reduced by changing a DC power source into variable output, and the efficiency of power can be improved.
