Electromechanical model and operating modes of high-voltage induction motor electric drive — Part II: Power losses

Abstract

The influence of the power supply in the operating modes of the induction electric drives is effected by the occurrence of voltage deflection in some cases. This is directly related to load of the shaft of an induction motor in driving different production mechanisms and reliable operation of the electric drive as a whole. Paper deals with evaluation of the combined expression of the voltage deflection and the value of the torque of inertia on the power losses in a powerful electric drive for a pump unit. Simulation is performed on high-voltage induction motor using the proposed model.
