This stepping motor subdivision controller is based on MCU-51, L297 and L298 are taken as driving modules. This system is composed of three parts as driving module, D/A transform and power supply. The drive of subdivision driver is used for getting the small torque angle. Meanwhile, the system will output the impulse signal to make the step torque angel have a slight changes so as to realize the subdivision control. Problems like low-frequency oscillation, out-of-step in high frequency and large torque angle in step motor are solved in this design. It make the control in step motor have the properties of high precision, low vibration and low noise.
