FIELD: electric engineering.
SUBSTANCE: device with indicator-less phase commutation additionally has functional transformer, realizing magnetization curve for given commutation angle of generator mode, and logical elements with switch, providing for use of different magnetization curves in engine and generator electric drive operation modes.
EFFECT: possible operation of electric drive without rotor position indicator in engine and generator modes.
