摘要

设计了一个以C8051F330单片机为控制核心的永磁无刷直流电机(无刷马达)电子调速器,实现了将PPM信号转化为PWM信号来实时调控电机转速的电子调速系统.系统硬件采用模块化设计,主要包括单片机控制模块、电源供电模块、电机驱动模块以及零点检测模块等部分.在完成整个系统的软硬件设计后,制作出实物并进行了测试,实验结果表明数字控制电子调速系统具有设计简单,调速稳定以及性价比高的特点.%The electronic speed regulator based on SCM of C8051F330 is designed for permanent magnet brushless DC motor (brushless motor), and can realize the electronic speed control system that the PWM signal being translated form the input signal of PPM real-time controls the motor speed. The hardware of the system adopts the modular design, which mainly includes the SCM control module, the power supply module, the motor driver module and the zero detection module. After the design of the hardware and software of the whole system, the material is made and tested, and the experimental results showed that the digital controlling system of the electronic speed system has the characteristics of simple design, stable speed regulation and high performance ratio.
