Analysis of Rotor Position Detection in a Position Sensorless BLDC Motor

介绍了一种电机的具体起动方法,并给出了一种位置检测电路的设计方案及其仿真和实验结果。实验表明,本系统可以实现电机的大范围可调速运转。

In order to detect the rotor position of the brushless DC motor without any sensors and control its rotate speed, this paper introduced a method to start the motor and then presented both the circuit design scheme of the rotor position detection and the simulation experiment result of this system. The result indicated that this system could regulate the rotate speed of the motor in a wide range.
