Abstract
The problem of overheating of electric motors of pumps of sewerage stations during the introduction of frequency converters of current is revealed. Modeling of the thermal state at different speeds of the rotor of the electric motor in the Comsol software package made it possible to determine the places for the possible installation of temperature sensors on the outer shell of the electric machine. Experimental studies have confirmed the adequacy of the obtained models and the proposed position of the temperature sensors.
