DEVICE FOR CONTROL OF STEP ELECTRIC MOTOR WITH ELECTRIC STEP SUBDIVIDING

摘要

Usage: for stepper motor control E in automatic control systems. The inventive device comprises a multichannel amplifier, each channel is formed by the keys 1,2, 4,7 diodes, current-sensors 5,6 and the control system is provided consisting of summing amplifiers 8.9, an analog switch 10, comparators 11,13 source 12 and reference voltage. The reference signal can have an arbitrary shape, and by reducing the step discreteness adjusting increased control accuracy. 3 yl.
