For the growing demand of the control products, the modern motor control technology is also becoming more and more important. The control based on single chip has been widely used in motor control areas. The stepper motors have become the third category beside the DC and AC motor. Traditional electromechanical energy conversion device motor plays a key role as in human life and production into the electrification process. However, electrification of the human society entered the era, the traditional motors can not fulfill the industrial automation and office automation and other motion control systems. With the development of a series of new motor control system, which has its own characteristics over, and is widely used is the stepper motor. The development of the stepper motor and computer industries are closely related. Since the stepper motor to replace the computer peripherals after small DC motors, to improve the performance of its equipment, and soon to promote the development of the stepper motor. For the applications of stepper motor and the control based on single chip design, This p
