Abstract—A procedure for thermal analysis of a run-capacitor single-phase induction motor characterized by two different wind- ings 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 anal- ysis 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 anal- ysis and experimental data. Both comparisons show an appreciable agreement, confirming the validity of the analysis.
