Abstract

A procedure for thermal analysis of a run-capacitor single-phase induction motor characterized by two different windings is presented. The procedure allows for the computation of the average winding temperature rise, and the temperature rises of the two different windings separately. The proposed thermal analysis is based on a lumped-parameter network commonly used for the three-phase induction motor. The paper illustrates how this network is adaptable for analysing the run-capacitor single-phase motor temperatures. In order to test the procedure, the predicted results are compared with those obtained from finite-element analysis and experimental data. Both comparisons show an appreciable agreement, confirming the validity of the analysis.
