Abstract

PURPOSE:To alleviate the irregular rotation of a DC motor by detecting a ripple current of the motor and feeding back it, thereby reducing the ripple current. CONSTITUTION:A DC amplifier 22 inputs a drive signal which is applied to a terminal 21 and a reference voltage which is applied to a terminal 23, and outputs a control signal to drive transistors Q11, Q12. On the other hand, a current (i) which flows through a motor 29 is detected by a resistor 30, and its AC component is fed back through a capacitor 32 to the drive signal input terminal of the amplifier 22. In this manner, a motor drive circuit can increase the output impedance in a relatively high frequency, can reduce the motor ripple current and can alleviate the irregular rotation of the motor 29.
