Finite element analysis of electric machinery

A nonmathematical description of the finite element analysis method is presented. Application of the method to determining the excitation requirement of a large turbine generator is discussed. The handling of short-circuit behavior and end-region fields is considered. An extension of the finite element technique is described that allows one to find simultaneously the electromagnetic fields, the winding currents, and the rotor motion in order to understand the effect of harmonic current and voltage on large squirrel-cage induction motors.<
