PSM20 Linear Slider Series permanent magnet stepper motor, Ø20 mm frame, can achieve ±0.05mm repeat positioning accuracy without encoder feedback, making them ideal for precision adjustment scenarios. These modules feature millisecond-level response speeds, and their permanent magnet rotors provide high holding torque, ensuring smooth low-speed motion. With advantages such as high cost-effectiveness, maintenance-free operation, and strong anti-interference capability, they often serve as the optimal solution for mid-to-low dynamic applications that do not require closed-loop feedback.
