摘要
为了检测无位置传感器无刷直流电机的转子位置信息,并使电机转速可调,介绍了1种电机的起动方法,并给出了1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 it＇s rotate speed, this paper introduced a method to start the motor and then presents both the circuit design scheme of the rotor position detection and the simulation experiment result of this system. The result indicated that this system can regulate the rotate speed of the motor in a wide range.
