UA78140U - Digital system for multi-motor electric drive control - Google Patents

Abstract

A digital system for multi-motor electric drive control comprises a speed sensor, first and second microcomputers, a digital-to-analogue converter, an analog-to-digital converter. Moreover, it comprises a speed setter, a tension setter and a digital unit, a reducer, a drive mechanism, whose output is connected to first input of an adder and a break passage. The digital unit is connected by a speed adder to an electric channel for a shaft rotation speed for resilient elements for speed and shaft torque angle, comprising a drive motor, whose output is connected to the speed adder negative output. The break passage comprises a power amplifier, a break electric motor, a break mechanism, whose output is connected to the second output of adder, whose output is connected to the tension sensor input, connected to the analog-to-digital converter input. Output of the last is connected to the negative output of digital tension adder, whose output is connected to the input of second microcomputer which transmits a signal to the second digital-to-analogue converter, whose output is connected to the positive input of tension adder.
