A motor controller is an important component in an electric vehicle. Research and development activities of brushless direct current (BLDC) motor controllers are devoted to getting better performance and higher efficiency. This topic still attracts researchers' interest all over the world, as can be seen from the amount of new scientific publication. BLDC motors in electric vehicle applications require transient performance improvement during start-up. PUI SKO ITS has been conducting research and development on BLDC motor controllers with trapezoidal commutation and field-oriented control (FOC) types. This paper presents an experimental performance comparison between the two BLDC controllers. Experimental results show that the trapezoidal controller is more responsive than the FOC controller, but the FOC controller has a smoother speed response than the trapezoidal controller. Moreover, the motor controller based on FOC produces smaller torque overshoot and smaller steady-state torque than the motor controller based on the trapezoidal commutation. This result calls for deeper analysis to push the performance of both types of the BLDC controllers to their limits and for further comparison in a possible higher stage of each controller's performance.
