Induction motors are one of candidates of automotive traction motor and generator. In automotive applications, the operating area is wide with respect to industrial standard motors. In addition, efficiency and torque improvements are required.
In this presentation, motor analysis and control configuration are presented. JMAG-RT model has been improved. In previous JMAG-RT model, standard induction motors are assumed, thus, variations in motor parameters are not very much considered. In the improved model, magnetic saturation and frequency dependence are considered. In addition, problems associated with induction motor analysis are presented.
