Abstract
Along with the reduce of petroleum resource and enhancement of environment protecting consciousness, electric motor becomes more and more important to people. What is more, some famous motor manufacturers begin to research electric motor. The government of China has already plough a large quantity of fund into the development of electronic motor. The task is item of Guangdong province. TMS320LF2407 DSP of TI corp. will become core of controlling. Using speed calculating capability and advanced peripheral device to realize digitalized control of driving device. Core of control arithmetic is double closed loop arithmetic. Exterior facilityof system become simple, reduces power and enhances veracity by using DSP chip. The paper emphasis on several work described as follows: Theory of thulium no-brush DC motor will be research. The framework and theory of TMS320LF2407 will be research. Selecting and establishing the method of control. Writing the soft of control arithmetic. Debugging program and analyzing result. The research of CAN protocol and the realization of CAN communication.
