Abstract

The optimum design technology using combind F.E.M and equivalent circuit it so fast and accurate that it can be applied to the optimum rotor design of an inverter-fed induction motor in high effieicncy motor making industry. The optimum characteristics for a rotor slot model of a 3 phase inverter-fed induction motor was previously verifyed by a time-step F.E.M. In this paper, four verification models with the design variables near the optimum point are designed to chech whether the characteristics of a slot model presented is not less than those of the near models. The outputs of whole models are analyzed in the experimental test. The economical and efficient selecting method of design variables for the computer simulation and experimental test is presented in order to assure the optimum point.
