.The novel element of the research is also in using an electromagnetic converter to reduce the vehicle’s overall energy consumption and to push the multiple disadvantages of using the insolated bipolar transistors.This study is based on the sizing of the electromagnetic converter and the two motor structures using the method of combined analytical finite elements.The program for sizing is coupled with two control laws relating to the motor types in order to choose the top performers according to good dynamic characteristics and energy saving.

.

The simulation results show, on the one hand, the equivalence of these structures from a dynamic characteristic point of view and, on the other hand, that the trapezoidal waveform motor structure is more economical.The design of an excitation system optimizing the consumed energy equipped by a hybrid excitation motor is also developed
