摘要
提出了一种集精确测量电机转速、上位机实时显示转速及数据存储的综合设计方案。该方案采用角速率传感器测量转速,将FPGA作为微控制器控制模数转换并将传感器的输出值存储并处理,提高了整个系统的处理速度。经试验验证,该系统能实时地显示电机的转速,有很好的稳定性和可操作性。
In measuring the speed of brushless motor,magnetic encoder is susceptible to be interfered by magnetic field from the motor,and optical-electricity encoder may not match the motor in size.This paper presents a system involving speed measurement,real-time display and data storage.In this system,the gyroscope meters the angular velocity,and DSP is the controller,regulating the A/D conversion and disposing the digital data with high rate.Experiments prove that this system can display motor speed in real time,with the advantages of stability and operability.It has practical significance to motor speed control and debugging.
