Abstract: In this paper, a control system for BLDC motor without position sensor based on TMS320LF2407 DSP is presented. The authors studied the rotor position detection of a permanent-magnet BLDC motor without position sensor. The hardware component and software design solutions for this system based on DSP are described. This system can simplify hardware structure very much and control motor stably and effectively.
Key Words: brushless DC motor; position sensor less; control system; Digital Signal Processing
