3、e 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, beside

4、s, 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 high

5、er 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

6、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

7、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 c

8、ircuit 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

9、 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

10、controllers for DC motors which can fulfill more conditions，consisting of Fewer system components, lower system cost and increased performances.Aiming at the characteristic of bed environment and serious disturbance，man

11、y Kinds of software and hardware technology are applied to improve systematic Anti--interference ability， which comprehensively improve systematic dependability and practicability. It has been proved by experiments th

12、at this system can make the high precise and multiple speed motor control come true. Stepping out the performance index is realized. Now this system has been put into experiment. Key word: DC Motor MCU Multiple Spe
