FIELD: electrical engineering. SUBSTANCE: system for regulating angular velocity of electric drive is built around phase synchronization circuit. Electric drive has photoelectric pulse transducer responding to shaft speed and position as well as transducer output signal conversion circuit that functions to raise frequency of transducer output signal. EFFECT: improved precision of maintaining controlled positions, enlarged functional capabilities of drive. 6 dwg
