Abstract

Parameters of a capacitor-start, capacitor-run single-phase induction motor with closed or semi-closed rotor slots are measured and a model for the investigation of the performance of the machine in the frequency domain under the influence of harmonic voltages is presented. An algorithm, taking into account the nonlinear rotor leakage inductance, is established. This algorithm is applied to estimate the current in the time domain, and the harmonic losses at rated-load operation without and with run capacitors are calculated. Computational results are compared with those from experimentation and the differences between both are discussed
