Abstract :
Switched reluctance motors (SRMs), which are simple and reliable motors, have attracted interest for electric vehicle propulsion systems. It is shown that an SRM offers a good performance at high acceleration and low speed driving conditions. Efficiency map of an electric motor is a very important characteristic specially when the motor is to be used in a wide range of speed and load variations, which is the case in electric propulsion systems. In this research, the efficiency map of an SRM is derived using a combination of the finite element method (FEM) and a mathematical model. This efficiency map has been used for different driving cycles to test the SRM performance as a vehicle propulsion motor.
