This paper deals with the characteristics analysis of 3-phase induction motors for electric power steering applications by combining finite element analysis with an equivalent circuit model. Induction motors for automobiles have high magnetic saturation due to size limitations. Accordingly, to improve the accuracy of the equivalent circuit analysis, it is necessary to consider the magnetizing reactance according to the magnetizing current. An equivalent circuit analysis method that takes into account the magnetic saturation of 3-phase induction motors is proposed and verified through a test.
