| 摘 要： | 提出了一种用傅立叶变换进行电机转速测量的新方法，以Labview为平台建立了实验系统，利用采集卡（或计算机声卡）检测被与电机同轴连接的齿盘调制的光电信号，由信号的幅度谱计算电机的转速。使用斩波器对此方法进行了实验验证，当转速范围为100—6000r／m，测量结果和实际值完全吻合。

| Abstract: | We propose a new method to measure motor speed by Fourier transform. The speed of a motor is obtained by perform a Fourier transform on the medulated signal from a toothed disc that is mounted on the motor. This method is validated by experimental results from an optical chopper. The measured results are agreement with the actual motor speed of the chopper in the range 100 - 6000r/m. |
