Abstract :
It is well-known that the separately-excited DC motor has effective torque (current) reduction characteristics in response to rapid increase of the rotational speed of the motor. This characteristic has been utilized in adhesion control of electric locomotives with DC motor. In this paper, we have proposed a new skid prevention method for EVs utilizing this characteristic and discussed the possibility of its implementation to IPM motor driven EV. In order to compensate for back-EMF, a back-EMF observer is introduced. The experimental results of the hardware skid simulator utilizing motor-generator setup verified the effectiveness of our proposed method
