Rotating field analysis using boundary element methods

Among the advantages of boundary element methods are the fact that only media interfaces need be discretized with elements and the number of unknowns for solution storage is small. Conventional eddy current boundary approaches can be employed to simulate rotational induced eddy currents and forces both For multiphase and single phase induction motors. The torque is computed by analyzing the power dissipated in the rotor at equivalent slip frequencies. This is especially useful for the single phase induction motor, since no Green´s function is available to simulate rotational induced currents
