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.
