Study of Stepping Motor Subdivision Driver

摘要：

In order to improve the load characteristics of stepper motor, give full play to the potential performance of a stepper motor, achieve higher performance, a constant frequency pulse width modulation sub-drive has been developed. Application of FPGA (Field Programmable Gate Array) devices for the stepper motor micro-step control, FET(field effect transistor) as the power driver switch, to achieve high-precision subdivision of drive systems, positive inversion control and automatic adjustment of winding currents. Experiments show that the stepper motor drive system not only small size, simplified system design, improved low-frequency stability and high-frequency torquefrequency characteristic, but also has a good adaptability and self-protection capabilities, improved the stability and reliability of driver.
