A steady-statemodel of a split-phase induction motor is investigated. Equivalent circuit parameters are estimated via a least-squares fit to experimental data and have been obtained through dc, locked rotor, and unloaded motor tests. Parameters were further refined using experimental data at rated load. In this test, instead of a permanent capacitor on the auxiliary winding, 90 degrees phase shifted voltages were applied to the main and auxiliary windings. This setup produced a circular magnetic field instead of an elliptical one, thereby eliminating the effect of high-order spatial harmonics.
