Abstract

PURPOSE:To reduce the impulsive torque ripple of a motor, by a method wherein a series circuit consisting of a resistor and a capacitor is connected in parallel with a resistor connected between the inverting input terminal and earth. CONSTITUTION:A reference voltage Vref is applied to the noninverting input terminal of an operational amplifier OP, and a first resistor Rs is connected between the inverting input terminal thereof and earth, while a second resistor Rf is connected between the output terminal thereof and said inverting input terminal. In addition, a series circuit consisting of a capacitor CT and a resistor RT is connected in parallel with the first resistor Rs. The output of the operational amplifier OP is fed to a motor M. Thereby, the current supplied to the motor M is prevented from varying impulsively. Accordingly, it is possible to reduce the impulsive change of the generated torque.
