APPLICATION OF THE COMBINED SCHEME OF SINGLE-PHASE INCLUSION OF THE INDUCTION MOTOR AS A MEANS OF INCREASING THE ENERGY EFFICIENCY OF HYDRAULIC DRIVE OF PROGRESSIVE MOVEMENT

Abstract

The peculiarities of the modes of operation of the hydraulic drive of translational motion with throttle speed control, in which the asynchronous motor with single-phase power supply is used as the primary actuator. A combined circuit of such an actuator with a phase-shifting capacitor is proposed, which allows to increase its energy efficiency in the forward and reverse modes of the hydraulic rod when changing the degree of opening of the hydraulic control valve by switching power circuits and using voltage regulation.
