VALVE-TYPE MOTOR DIGITAL CONTROL SYSTEM Russian patent published in 1997 - IPC

FIELD: control systems for commutatorless DC motors. SUBSTANCE: control system has digital position, current, and voltage sensors, digital period meter, single-phase phase shifter, multiphase amplitude regulator, three read-only storage devices, logic inverter, microcomputer with microprocessor unit; microcomputer is made for implementing compiled algorithms. This eliminates motor inverter control voltage unbalance due to elimination of subharmonic and DC component under steady state conditions. EFFECT: reduced fluctuations of motor torque. 10 dwg
