基于PIC单片机的无刷直流电动机控制器设计

摘要

本文介绍了以单片机PIC为核心的无刷直流电动机控制系统的设计.本系统采用电流与速度双闭环控制的结构.实验验证了此设计方案的可行性和优越性,即控制电路简单、使用器件少、成本较低、保护措施可靠,提高了控制系统的性能.本设计对无刷直流电机在其他领域的应用有一定的帮助和借鉴,具有广泛的现实意义.%The design of brushless DC motor control system based on PIC16F87 is introduced in this paper. The system uses current and speed double-loop control structure. The experiment proves the feasibility and superiority of the design, which are simple control circuit, fewer devices, lower-cost, reliable protection measure, and improves the performance of the system. The design offers BLDCM a certain help in other areas of application and has a wide range of practical significance.
