Optimum design of three phase induction motor based on efficiency optimisation

The nonlinear optimisation method of Hooke-Jeeves, in which partial derivatives are not required, has been employed for optimum design of the three phase induction motor. The method is capable of producing an optimum design which meets or exceeds all constraints and performance specifications. The results obtained by this technique is fully comparable with a more complicated optimisation technique such as the Han-Powell method. The optimisation method was able to approach the optimum operating point, satisfying the imposed constraints and achieving a stable optimum design. The optimum design was achieved with 117 iterations and 290 seconds computation time on PC/AT
