As the artery in the area of electric drive systems, DC drivers become more and more important modern production. For a long time, DC motor has possessed the main role in the area of electric drive because of its neatly adjustment, simple method and smooth timing in a wide range,besides,its control performance is excellent. DC motor is widely used on the automatic equipments ,such as CNC and industrial robot. As the scale of production becomes larger and larger the demand and requirements become higher and higher,so the research on improving the DC controlling system behavior has important sense. This paper system of DC motor multiple speeds based on STCMCU is designed,as its necessary test equipment. It finished the total project design of system and model selection. The hardware and software design of the system according to the preceding solutions are discussed detailed. For the hardware part after a dissertation on the whole design，the core hardware of the control system is the STCMCU,the paper introduced the details of some hardware problem，including input circuit of keyboard，serial communication circuit, measure circuit, D/A switching circuit and display circuit and so on. The method of software planning for it is also discussed. For the software part，with the introduction of modular design concept some procedure flow charts of main program subroutine are offered. The paper designs the software which achieves the functions，such as install parameters, download parameters，startup stop accelerate and decelerate. This new family of STC enables cost—effective design of controllers for DC motors which can fulf
