Abstract

PURPOSE:To stabilize the operation of a motor by performing a feedback control when the voltage of a speed setter is above a fixed value while an open loop control is performed when it is below the value. CONSTITUTION:An output voltage of a speed setter 6 is inputted into a voltage- frequency conversion circuit 9 and converted to a pulse. At the same time, the output of the speed setter 6 is inputted into a voltage setter 14 while compared with a voltage from a smoothing circuit 8 and combined with the output of the voltage setter 14 through a voltage control amplifier 7 to be fed to a PWM circuit 11. At this point, when the voltage of the speed setter 6 is larger the level at the intersection with the output voltage of the voltage control amplifier 7, the output of the voltage control amplifier 7 is inputted into the PWM circuit 11 while the output of the speed setter 6 is inputted into the circuit before the voltage reaches the level. Accordingly, the stable operation of a motor 4 is done by switching a feedback and open loop control in the inputting of a base drive circuit from a bridge circuit 3.
