(15) Realization for Permanent Magnet Synchronous Motor Control by Micro Controller SN8P1708 Chip. Student : Yu-Zhong Wu. Advisor : Dr. Shir-Kuan Lin. Department of Electrical and Control Engineering National Chiao Tung University. ABSTRACT Since the motor is invented, through people’s constant improvement and innovation, the motor becoms a kind of indispensable important component in the industry now. We can nearly all see the existence of the motor in the electric products inside all offices, it is like a printer, scanner, CD-ROM driver, hard disk,etc...So, how to control the motor becomes an important knowledge. This thesis mainly describes the realization for permanent magnet synchronous motor control by SN8P1708 chip manufactured by Sonix. In firmware, we use assembler codes to relaize control transfer between host and device. In hard ware, we drive permanent magnet synchronous motor by six-step inverter circuit. It’s stabilize to motor running by close-loop control used with hall sensor. It is more easy to operate this system by used with keyboard and LCD display.. ii.
