A combined finite element-state space modeling environment forinduction motors in the ABC frame of reference: the no-load condition

A combined finite element state-space modeling environment capable of predicting no-load induction motor performance is introduced. The authors focus on the model derivation and the no-load simulation. The model is based on the natural ABC frame of reference and includes full effects of discrete winding layouts, magnetic saturation, and space harmonics. The model does not require the existence of actual motor hardware. The method is totally flexible and allows the design engineer to answer what-if questions before any resources are committed to prototyping. The method was shown to produce motor parameter results which correlate very well with corresponding test data of an example 1.2 hp 200 V three-phase induction motor
