Experimental test of the near optimal models for an inverter-fed induction motor

The optimal design of the rotor slot for an inverter-fed induction motor was performed in our lab. The purpose of the paper is to verify the optimal point obtained from the simulation by the experimental method. A sensitivity analysis is performed, and the models near to an optimal point are selected. As a selecting process of the models, 2 design variables with high sensitivity are selected out of 5 design variables, and 2 models near to the optimal point are decided. The time-step F.E.A and the experiment are performed to verify the optimal point and the performance improvement of the optimal model.
