Large reluctance motor design-nonlinear programming approach

The non linear programming approach is used to predict an optimum design for a large reluctance motor of the flux guided type. It is shown that for large reluctance motors, it is necessary to use more than 1 FG/pole. A rotor design with equal permeance factors (W/T) for each flux guide will always be required. The Powell method along with the SUMT technique is employed to optimize the design whose predicted performance is more than that achieved by an equivalent induction motor.
