DIGITAL ELECTRIC DRIVE Russian patent published in 2014 - IPC G05B11/00 H02P7/00 

FIELD: electricity.

SUBSTANCE: invention suggests a digital electric drive containing a setting device which output is connected to a position regulator with its output connected to a variable-speed control unit, a pulse-width modulator, a servomotor, at that the servomotor is made as a disc toothless thyratron motor divided into three segments and each segment is coupled to an individual power amplifier and a phase current sensor for each segment, which are coupled to a torque valuator, output of the latter is connected to a torque controller, which second input is connected to the output of the variable-speed control unit and output is connected to the pulse-width modulator, the output of the modulator is coupled to three power amplifiers of the motor segments, the electric drive is equipped additionally with a position sensor, which input is connected to the motor and output to the position sensor controller, the output of the controller is connected to the second input of the position regulator and to the second input of the variable-speed control unit through a velocity valuator.

EFFECT: improving reliability index of the digital electric drive system with simultaneous simplification of its assembly and repair procedure due to use of a thyratron motor with a disc stator divided into three segments.
