摘要
采用无传感器无刷直流低速电机专用调速控制芯片ML4425,设计制作了航模用直流无刷高速电机的控制器。针对目前航模用直流无刷电机速度高的特点,对用于直流无刷低速电机的传统ML4425控制系统中的相关环节进行了改进,尤其是电机的启动、驱动和保护部分。简化了航模用直流无刷高速电机的控制系统,减少了成本。
In this paper,a dedicated control chip is used to design a drive circuit of a low speed sensorless DC brushless motor.This paper has done some change of the traditional control system of ML4425,in order to adapt to the high speed of the DC brushless motor used in aircraft model,especially in parts of start,drive and protect.Simplified the control system of the DC brushless motor,so it can reduce the cost.
