Rotating field analysis using boundary element methods

Among the advantages of boundary element methods are the fact that only med ia interfaces need be discretized with elements and the number of unknowns for solution storage is small. Conventional eddy current boundary approache s can be employed to simulate rotational induced eddy currents and forces b oth for multiphase and single phase induction motors. The torque is compute d by analyzing the power dissipated in the rotor at equivalent slip frequen cies This is especially useful for the single phase induction motor, since no Green's function is available to simulate rotational induced currents.
