摘　　要：设计了一种采用透射式齿轮盘的电机测速装置。该设计采用槽型光电传感器配合自制的透射式齿轮盘来采集速度信号,产生一系列数字脉冲信号,同时采用频率-电压转换芯片LM2907将脉冲信号转化为电压信号。此装置应用于模型车上,不仅可以实现脉冲测速,还可实现电压测速,具有结构简单,安装方便,检测方式多样,检测精度高等特点。A motor speed detection device using a transmission-gear is introduced. The device uses the groove photoelectric sensor with self-made gear transmission encoder to acquire the speed signals and produce a series of digital pulse signals. At the same time the frequency-voltage conversion chip LM2907 is used to transform pulse signals into voltage signals. This device is used in the model car, it can not only use the pulse to detect speed, but also use the voltage to detect speed. Besides, the device has simple structure, diverse ways of detection, high detection accuracy and easy to install.
