CONTROL METHOD OF SYNCHRONOUS MOTOR IN OSCILLATION MODE Russian patent published in 2019 - IPC H02P25/32 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering and can be used in machine building, electrical machine building, measuring, testing equipment, tribology. In the method of controlling a three-phase synchronous motor (SM) with a rotor on permanent magnets, an oscillatory electromechanical system is used with two controlled channels and provide various practical implementations for creation of mechanical oscillation generators as controlled sources of oscillatory electromagnetic moment, force and power. Distinctive features of the latter are continuity of electromagnetic moment, smoothness of reverse, which increases reliability and safety of corresponding technical objects. Besides, due to two-channel control of oscillation parameters, operation in energetically favorable resonance area is achieved, losses are minimized and efficiency of technical devices is increased. Paths of achieving the resonant region are indicated.

EFFECT: technical result is wider range of oscillation frequencies, higher dynamic power in load, use of installed power of actuating SM power all three phases of power supply from corresponding adjustable transducers, broader functional and adjustment capabilities.
