R. Bhuvaneswari, S. Subramanian · Electric Power Components and Systems · 2005
Three-phase induction motors are designed to meet various special requirements. Irrespective of these requirements, the basic conditions to be fulfilled are (1) The starting torque must be high, and (2) Operating efficiency and power factor must be as high as feasible. This article discusses the formulation of design optimization of three-phase induction motor as a nonlinear multivariable programming problem to meet the above requirements. Three different objective functions were considered. The simulated annealing algorithm was used to obtain an optimum design. The algorithm was implemented on three test motors and the results indicate that the method has yielded a global optimum. The proposed algorithm results are compared with the conventional design results to select a suitable optimal design of the induction motor. The performance of the motor is found to improve with application of this algorithm.
