Abstract :
A method for accurately predicting the steady-state performance of squirrel cage induction motors is presented. The approach is based on the use of complex two-dimensional finite element solutions to deduce per-phase equivalent circuit parameters for any operating condition. Core saturation and skin effect are directly considered in the field calculation. Corrections can be introduced to include three-dimensional effects such as end-winding and rotor skew. An application example is provided to demonstrate the effectiveness of the proposed approach
