DEVICE FOR SUPPLY OF A SYNCHRONOUS HYSTERESIS MOTOR WITH PHASE OVEREXCITATION Russian patent published in 2018 - IPC H02P23/04 H02P25/64 H02P27/06 

FIELD: electrical engineering.

SUBSTANCE: invention relates to the field of electrical engineering and can be used in electric drives with synchronous hysteresis motors. Device for supplying a synchronous hysteresis motor with phase overexcitation contains a rectifier, a master oscillator, a frequency divider with a pulse distributor; inverter that is executed according to the current inverter circuit, to the output of which a synchronous hysteresis motor and a compensating capacitor are connected. Overexcitation control pulse is fed to the rectifier current control input and to the input of the master frequency control unit, the other input of which is supplied with the supply voltage of the synchronous hysteresis motor, output of this unit is connected to the frequency control input of the master oscillator, whose output through the frequency divider with the pulse distributor is connected to the input terminal of the power inverter of the current inverter.

EFFECT: technical result is a reduction in the installed power and the level of electromagnetic interference.
