Abstract

Zero running emission, sustainability and efficiency of Electric Vehicle (EV) make it appropriate option for future transportation. In-wheel propulsion system of electric vehicles has been one of the main research concentrations in past decades. Brushless DC (BLDC) motor is the most suitable in-wheel motor because of its high efficiency, torque/speed characteristics, high power to size ratio, high operating life and noiseless operation. In this chapter direct torque control (DTC) switching technique with digital pulse width modulation (PWM) speed controller of BLDC motor for drive train system of EV has been reported. Effectiveness of the proposed BLDC motor drive is investigated through simulation and experiment. Obtained results show effective control of torque and remarkable reduction of torque ripple amplitude compare to conventional reported switching techniques. Improvements of in-wheel motor’s torque controllability result to more efficient and safer electric vehicles.
