FIELD: engines and pumps.
SUBSTANCE: invention can be used for control and adjustment of operating parameters of electrically driven devices, e.g. pumps, impellers, screw conveyors, rotors or similar devices. Proposed method consists in cutting out power supply during multiple time intervals in drive operation, measuring voltage fed by motor during said intervals, comparing said measured voltage with reference voltage, and, if required, compensating for possible deviations of at least one operating parameter of electrically driven device.
EFFECT: efficient control and compensation for undesirable variations of operating parameters, say, drive shaft angular speed.
