Generalised harmonic analysis for the steady-state performance of sinusoidally-excited cage induction motors

A generalised technique for applying harmonic analysis to determine the steady-state performance of a cage induction motor with any stator winding connection and any excitation configuration, is described. Explicit formulas are given for all the impedances required. The method is verified by means of comparison between experimentally measured variations of input power, input current, and electromagnetic torque and those calculated using the technique.
