The application of the finite element method for predicting the performance of a three-phase squirrel cage induction motor under wide ratio pole configuration is described. This paper investigates the magnetic field distribution in a 2 hp three-phase induction motor. Utilising a triangular finite element method, the magnetic field in the motor is analysed under different pole settings at various balanced magnetomotive forces (mmf). From the field solutions, the flux linkages and slot leakages are found for a wide range of magnetising currents. An experiment using a 415 V, 2 hp, three-phase induction motor having 36 stator slots with 72 terminals available outside, tested at different pole configurations.
