Abstract

PURPOSE:To realize power saving control, highly following characteristics and the reduction of rotating ripple in motor servocontrol by comparing an artificial speed pulse from a pulse conversion circuit with a speed instruction pulse to conduct servocontrol. CONSTITUTION:When an encoder pulse (i) converted from a signal which corresponds to the rotation speed of a motor 8 and is outputted from an encoder counting up the rotation speed of the motor 8 is inputted to a pulse converting circuit 13, an artificial speed pulse (k) forming a pulse array by adding a subscribed number of pulses (j) to the back of the encoder pulse is outputted to a pulse comparator 11 and compared with a speed instruction pulse (h) to form a pulse array with the pulse array with the pulse width and polarity corresponding to the phase difference. The pulse array is added to a power amplifier 12 as an error signal (l) to drive the motor. Since the encoder pulse (i) is converted into the thicker pulse (k), the amplitude of current is regulated short and averaged.
