Abstract :
A general time-stepping approach is presented to solve coupled field-circuit motion problems for the analysis of three phase and single phase induction motors. The circuit equations are used to describe the winding connections, to include rotor end-ring effects and possible external impedances, and to support voltage source with arbitrary waveforms. In addition, a moving surface method is proposed to deal with rotor movement without any remeshing
