ives, optical isolator TPL5211, etc., to build a stepper motor controller and driver as one of the stepper motor control and pulse distributor PMM8713 to plete a variety of operational control stepper motor, Reversible control of the stepper motor 3phase 6 shot works and deceleration control The entire system is modular in design, simple structure, reliable, and can be achieved through humanputer interaction to change the interface settings, simple to operate, easy to grasp. The system can be applied to the stepper motor in mechatronics control the majority of occasions Stepper motor due to its openloop system consisting of both a simple, inexpensive, and very feasible, and therefore has a very wide range of applications in many areas of printers and other office automation equipment and a variety of control has proved that, based on the microprocessor controlled stepper motor has better performance than conventional stepper controller, more simple, convenient and main object of study of this design is openloop servo system is the most monly used actuator stepping motor. Keywords: stepper motor; microcontroller; positive control; acceleration and deceleration control 目錄 目錄 摘 要 .............................................................................................................................I Abstract .........................................................................................................................
