Sensorless Self-starting and Control Strategy of Brushless DC Motor
Brushless DC motor with sensors have problems ,such as theirs large sizes, high costs , limited applications and so on.In order to solve them,based on STM32F103 MCU and taking it as the core,this essay uses position sensorless control based on square-wave drive,it realizes the switching of zero speed to the motor closed-loop state through three-step start technique,it checks rotor position and speed by back-EMF method.At last,it makes the motor run normally. The effectiveness and feasibility of the control scheme proposed are verified through experiments.
