Motor drive system is one of the core components of electric vehicles. To meet the electric vehicles performance requirements: starting, accelerating, climbing and other driving conditions demand, motor drive system requires high torque at low speed, high power at high speed, wide speed control range, etc. This paper takes a motor-driven electric vehicle system design as an example, from the control...
For pure Electric Vehicle (EV), motor is the one and only power source. Comparing with industry motor, the motor drive system in EV has several challenges, such as dynamic running with unpredicted drive cycle, high torque/power density to reduce the vehicle curb weight, robust limp-home functionality to ensure vehicle can run even when some key components failed, life-time guarantee, wide speed control...
