Based on the requirements of electric vehicles on electric motor drives, this paper presents three criteria to evaluate motoring operation of in-wheel switched reluctance motor drives for electric vehicles. They are the average torque, the average torque per rms current, and torque smoothness factor. They indicate the motoring torque, copper loss and torque ripple, respectively. The model of motoring...
Three criteria are proposed to evaluate braking operation of switched reluctance motor drives for electric vehicles. They are the average torque, the average torque per average excitation power and the average torque per phase rms current. They imply the braking torque, the efficiency of braking operation and the copper loss. Thus, the effects of the turn-off and turn-on angles on these criteria are...
Generic algorithm is used to optimize the turn-on angle and overlap angle and the torque ripple factor is selected as the fitness function. Four types of torque sharing functions for switched reluctance motor drives are evaluated by using the torque ripple factor. The investigation shows that the cubic torque sharing function is the prime choice in consideration of the minimum torque ripple, the simplicity...
