Design And Realization Of The SteppingMotor Control System Based On SCM

Stepping motor is a kind of component using electric pulse signal to control winding elements to realize angular displacement. Comparing with other electric motor, it is easier to realize accurate control, no accumulated error and so on so forth. Thus, it is got extensive application. In order to gain excellent manipulative result, there appear a lot of stepping motor control systems. Among them, the system using SCM as the core part of the control system is used widely. Many this kind of control systems have done absolutely good at the step motor drive, such as the technique of subdivision of drive. But some systems are a little bit complicated, which does not match with some comparatively simple control, causing some waste on investment. Some system is not easy to operate, weak in alternation. Furthermore, techniques in today's vocational teaching materials are entirely different, leading to some kinds of chaos in the exercitation, not combining some techniques which should be. Consequently, this thesis focuses on how to design a simple step motor control system, which has complete function, strong adaptability, easy to operate, high dependability, mixing electronic technique, SCM technique and motor control technique. This thesis will firstly introduce the development and application situation of stepping motor and some common control systems and drive techniques; what's more, it will illustrate the working principle of step motor, then, using SCM as a main controller to put forward the whole system blue print of the hardware design. Based on this, all specific designs on electrical circuits in every module will be followed. Finally, illustrate the steps of how to develop the software of control system and programmed design.
