What is a Servo Stepper Motor?

A Servo Stepper Motor is a high-performance stepper motor equipped with an encoder. At its core, it remains a stepper, but through closed-loop control, it aims to combine the benefits of both stepper and servo motor technologies.

The Ideal Cost-Effective Solution

Are you concerned that a standard stepper motor might lose steps due to sudden resistance changes during complex carving, leading to misalignment and scrapped work? At the same time, is a true servo motor stretching your budget?

This Servo Stepper Motor is the high-value solution crafted for this exact scenario. It retains the high holding torque and cost-effectiveness of a standard stepper while utilizing a built-in encoder for closed-loop control. This system continuously monitors and instantly corrects any positional errors, permanently eliminating the issue of lost steps and guaranteeing pinpoint accuracy for every single carve you make.
