Abstract :
Brushless direct current (BLDC) motor with the high power density and the high efficiency characteristic is been used to electric vehicle. The mathematical model of BLDC motor under rotor flux linkage direction reference frame was given. The chart of field-weakening vector control and basic principle of field-weakening control strategy were analyzed. The theory of field-weakening based on reactive power with BLDC motor was proposed. The drive system of field-weakening based on reactive power using BLDC motor was designed. The experiment and result was test the validity of field-weakening based on reactive power with BLDC for electric vehicle application.
