In order to determine the optimal machines dimensions and the current angle making a trade-off between the maximum output torque and a high power factor, a cyclic coordinate method coupled with the FEM is applied.
A cyclic coordinate method [17,18] using the unknown parameters as the search directions, is applied to maximize the objective function successively along each coordinate.
The optimization method based on the cyclic coordinate method coupled with FEM, has been applied successfully for the design of synchronous reluctance machine structures with a massive rotor and with a flux barrier rotor for given stator dimensions.
