Abstract

PURPOSE:To prevent giving uncomfort to a driver by decreasing the high frequency component of a drive signal, which is entered into a motor driver circuit, through an integrating circuit to a great extent, and thereby lessening noise from the motor. CONSTITUTION:Input to a motor is determined from the torque generated by steering, and signal to control the number of revolutions of the motor from D/A conversion thereof is passed to a positive input terminal 5a of an error amplifier 5 from a D/A converter 4 via a resistance R1. This input terminal 5a is grounded via a parallel circuitry of a resistance R2 and a capacitor C1, wherein the resistance R2 and capacitor C1 constitute an integrating circuit A. Output signal from the output terminal 5c of this error amplifier 5 is entered into a motor drive circuit 6. A parallel circuitry of a resistance R3 and a capacitor C2 is interposed between this output terminal 5c and a negative input terminal 5b, wherein the resistance R3 and capacitor C2 constitute an integrating circuit B.
