Abstract：using STM32F103ZET6 microcontroller as the core control device, is mainly used on motor is connected with the sampling resistor and sensor made of TLC27L4 DC brushless motor speed device, the circuit into a pulse signal, and then transmitted to the SCM system for technical operations, and will measure the speed of the results in the LCD. The whole device has high accuracy, stability and reliability. It can effectively collect the speed of motor's normal operation, occupy less space and is convenient to use, so as to meet the requirement of motor speed measurement.
