FIELD: electric engineering, possible use for driving down-pumps, used in oil industry. ^ SUBSTANCE: in the method for controlling gated electric engine and device for its realization, launch and rotation of rotor is provided for on basis of EMF signals in anchor winding sections, free from current, transformation of EMF signals by normalization device to discontinuous signals of logical level, determining by microcontroller of commutation moments and their displacement depending on value of load current, speed of rotor rotation and inductiveness of anchor winding sections. Commutation moments are computed and displaced relatively to moments of transition of EMF of free sections of voltage levels, different from zero. Device is provided with block for shifting bearing level, consisting of current indicator, voltage indicator, two adders and inverter. Displacement block is mounted in normalization device between splitter and block of comparators. ^ EFFECT: increased efficiency of electric motor. ^ 2 cl, 3 dwg
