Study on the novel main circuit topology of stepping motor drive

In this paper, a new type of stepping motor-drive main circuit topology has been research. The characteristic of main circuit with traditional stepping motor driver of the difference between the novel main circuit topology was research. The control strategy of the four phase mixed stepping motor was analyzed based on the topology, and given the used of digital signal processor of the stepping motor digital control system. Simulation and experimental results show that the main circuit topology can accelerate the winding current response performance of four phase mixed stepping motor, effectively improve high speed stepping motor operating characteristics.
