FIELD: electrical engineering.
SUBSTANCE: invention relates to electrical engineering and can be used for control in electric drive with synchronous hysteresis motors. Device for synchronous hysteresis motor electric power supply contains inverter, current sensor, included into inverter output current circuit, driving oscillator and synchronous hysteresis motor rotor instantaneous speed low-frequency component selecting unit, which input is connected to current sensor output, and its output is to driving oscillator frequency control input and inverter output voltage value control input.
EFFECT: technical result is active power continuous oscillations occurrence prevention in all synchronous hysteresis motor operating modes.
