Design of High-precision Subdivision Driver of Stepper Motor Based on C8051F021 MCU

摘要

In this paper, principle and features of a subdivision method of stepper motor named "current vector even rotating with constant-amplitude" are introduced. Based on the above principle, a design scheme of hardware and software about the high-precision subdivision driver of stepper motors based on C8051F021MCU and LMD18200 H-bridge is established and its working principle is analyzed. In the end of this paper, the experimental results are given.
