The DM series is a two-phase digital stepper driver launched by GRMOT Company. It adopts a servo like control principle and integrates vector control technology, built-in micro segmentation technology, and adaptive filtering technology, greatly optimizing the performance of the stepper motor. It runs smoothly at low, medium, and high speeds with low noise. The precise and smooth pure sine current vector control technology effectively reduces motor heating.
