Analysis of split-phase induction motors using an impedance matrix

This paper puts forward a simple but effective impedance matrix analysis technique that allows the analysis of a split-phase induction motor. Using this technique, the asynchronous torques as well as the main performance of a split-phase machine can be predicted to aid design of the machine. The model is tested against the SPEED software from the University of Glasgow, which uses the cross-field and rotating field techniques, which theoretic machines with windings containing MMF harmonics.
