Design and Simulation of Brushless Direct Current Motor Drive

Instead of mechanical commutator for DC motor, Brushless DC motor used electronic commutator. And brushless DC motor (BLDCM) extended the effective using time of a motor and eliminated some problems caused by the mechanical commutator, such as electromagnetic interference, brush wear, frequent maintenance and etc. At the meantime, brushless DC motor inherited a few advantages from DC motor, like wide speed range, large torque, stable operation, low noise, and high power density; there is great significance in researching BLDCM control system. This paper researches the application of fuzzy control strategy in BLDCM (brushless direct-current motor) control system. The design and simulation of BLDCM control system based on DSP controller also presented in the paper.
