无刷直流电动机控制系统设计方案

摘 要 无刷直流电动机是在有刷直流电动机的基础上发展起来的。现阶段，虽然各种交流电动机和直流电动机在传动应用中占主导地位，但无刷直流电动机正受到普遍的关注。自20世纪90年代以来，随着人们生活水平的提高和现代化生产、办公自动化的发展，家用电器、工业机器人等设备都越来越趋向于高效率化、小型化及高智能化，作为执行元件的重要组成部分，电机必须具有精度高、速度快、效率高等特点，无刷直流电机的应用也因此而迅速增长。本设计是把无刷直流电动机作为电动自行车控制系统的驱动电机，以PIC16F72单片机为控制电路，单片机采集比较电平及电机霍尔反馈信号，通过软件编程控制无刷直流电动机。 关键词 无刷直流电动机 单片机 霍尔位置传感器 Abstract Brushless DC motor in a brush DC motor developed on the basis of. At this stage, although exchanges of all kinds of DC motors and motor drive in the application of the dominant, but brushless DC motor is under common concern. Since the 1990s, as people's living standards improve and modernize production, the development of office automation, household appliances, industrial robots and other equipment are increasingly tend to be high efficiency, small size and high intelligence, as the implementation of components An important component of the motor must have a high accuracy, speed, high efficiency, brushless DC motor and therefore the application is also growing rapidly. This design is the brushless DC motor as the electric bicycle motor-driven control system, PIC16F72 microcontroller for control circuit, SCM collection and comparison-level electrical signal Hall feedback, software programming through brushless DC motor control .
