中文摘要：

变频调速监控系统对无刷直流电机的动态性能数据信息的监控有重要影响。本文以无刷直流电机为对象，设计了一套无刷直流电机变频调速监控系统。系统基于C社，在无刷直流电机进行调速的单闭环控制的基础上，通过串口通信协议进行数据采集后进行波形显示以及数码管显示，实现对无刷直流电机的调速监控。

英文摘要：

The variable frequency speed control system has an important influence on the dynamic performance of the brushless DC motor. In this paper, brushless DC motor as the object, the design of a brushtess DC motor speed control system. The system is based on C#, the speed of the brushless DC motor closed-loop control based on the data collected through the serial communication protocol for waveform display and digital display, to realize the speed control of Brushless DC motor.
