Abstract

In this paper, we study the temperature rise in an asynchronous motor with nonsinusoidal voltage feeding. The stator and rotor current harmonics are calculated using a time step method. Inverse problem techniques are used to evaluate the homogenized electromagnetic and thermal characteristics of the stator windings. Temperatures in sinusoidal approximation and harmonic currents are compared with experimental measurements.
