Abstract

PURPOSE:To drive a motor at high speed with low voltage and low noise by providing a motor between a T type dropper amplifier and a T type chopper amplifier and driving the motor in a chopper operation higher than an aural frequency even in a stationary range. CONSTITUTION:The first servo amplifier 3 of a T type dropper amplifier having a pair transistors at the final stage and the second servo amplifier 7 of a T type chopper amplifier having pair transistors at the final stage are formed, and a power source is connected across the transistors. Then, a motor 4 and a current detector 5 are connected between the connecting points of the pair transistors. Thus, an error signal supplied through a limiter 1 is obtained, thereby controlling a current direction of the motor 4 by the servo amplifier 3 and noninverting amplifier 2, and the current value of the motor driving current is controlled by the servo amplifier 7, noninverting Schmitt circuit 6 and a Miller integrator 8.
