Abstract
PURPOSE:To control the hunting phenomenon at a motor stop point at the time of zero speed command, by reducing the ripple of a speed detection signal by the output of a comparator circuit at the time of zero speed command. CONSTITUTION:A monostable multivibrator circuit 10 inputs a pulse signal g from a pulse generator 9 to output the pulse h of a certain time length. Then, said pulse h is integrated and converted into a speed signal k. A speed error amplifier 6 supplies a motor with the deviation between a speed command e and said speed signal k via a power amplifier circuit 7. On the other hand, a comparator circuit 12 makes an analog switch 11 operate when said speed command is zero, to increase the integral action time of an integration circuit. In this manner, when the motor is turned by an external force or the like at the time of zero speed command, said motor returns to the original condition by a smooth counter torque.
