FIELD: electrical engineering.
SUBSTANCE: invention relates to the field of electric engineering, in particular to the electric motor of the consumer having the engine drive, with the system of continuous performance control. Technical result is achieved by the fact that electric motor is equipped with sensors for temperature of windings and/or bearings directly connected to control device intended for control of consumer efficiency. Control device will limit compressor flow rate and limit power when one of thermal limits is reached or exceeded, that is when one of the measured temperatures reaches or exceeds a predetermined maximum temperature value, with application of which corresponding maximum temperature is set for each of sensors or at least some of them.
EFFECT: technical result consists in achieving maximum efficiency without risk of damage in operating conditions and in protection of engine against overheating.
