DIGITAL ELECTRIC DRIVE Russian patent published in 2010 - IPC G05B11/26 G05B11/36 H02P7/29 

FIELD: electricity.

SUBSTANCE: digital electric drive, comprising setting device, serially connected position controller, speed controller, current controller, the second inlet of which is connected to metering outlet of actuating motor, shaft of which via reducer is mechanically connected to control object, pulse width modulator (PWM), outlet of which is connected to power amplifier, additionally includes generator of reference voltage, sensors of rough and accurate count positions, angle-code converter, speed sensor, besides speed and position sensors are rigidly fixed on actuating axis of electric drive downstream reducer, control inlets of position sensors are connected to outlet of reference voltage generator, and outlets of position sensors are connected to angle-code converter, outlet of which is connected to the second inlet of position controller, outlet of speed sensor is connected to the second inlet of speed controller.

EFFECT: expanded speed range of electric drive towards subsonic speeds as a result of increased accuracy of angular position measurement in actuating axis of drive.
