Design of measuring circuit of motor speed based on Proteus

Abstract

In this paper, 51 single chip microcomputer, photosensitive element and 1602 are used to design the motor speed measurement circuit based on grating method, and Proteus software is used to build the circuit and function verification. Finally the project achieves the motor speed measurement and adaptive content display under different precision, the project simulation verification results are well. At the same time, on this basis the construction of motor speed measurement circuit is discussed and promoted.
