Abstract :
The FEM is a favored motor design tool for its high accuracy. Magnetic equivalent circuit analysis, an alternative to FEM, is becoming popular for its fair accuracy and quick repetition of computation. An equivalent circuit model of a brushless DC motor is developed and its ability to accurately predict various motor performance parameters is assessed
