Methods of Performing Thermal Calculation of an Asynchronous Motor Taking Into Account the Theory of Similarity

Abstract

In the article discusses methods for calculating the thermal state of an asynchronous motor drive, taking into account the operating modes of an asynchronous motor, provides methods for calculating the thermal state of an asynchronous motor operating in electric drive mode, assessing the thermal state of traction asynchronous motors will increase the energy performance of the electric drive and will continuously monitor the thermal state of an asynchronous traction motor, timely prevent possible emergencies.
