Design and Simulation of An Inverter-fed Induction motor for Electric Vehicles

Abstract

The variable-frequency induction motor used in electric vehicle is investigated in this paper. Firstly the design method of a voltage inverter-fed induction motor is introduced, and then the calculation methods of electromagnetic parameter are presented and programmed in VB (Visual Basic) software. Based on the geometrical dimensions and parameters, a simulation model in the vector control system is used to predict the performances of this machine. The comparison between the simulation results and the experimental results shows that the performances of the design machine are matched for its application.
