Design of Brushless DC Motor Controller with Position Sensorless Based on DSP

Wenjuan Sheng

Abstract

This paper presents a controller of brushless DC motor with position sensorless base on DSP.The DSP chip TMS320LF2407 is employed in the design,and the rotor position is detected by testing the back-EMF signal.The paper introduces the software design and design of detail circuits,including,drive circuit,rotor position detection circuit,current detection circuit.
