Twotrees NEMA 17 Stepper Motor 17HS4401

The Twotrees NEMA 17 Stepper Motor 17HS4401 is a high-precision 2-phase hybrid stepper motor designed for reliable and accurate motion control in 3D printers, CNC machines, laser engravers, robotics, and other automated equipment. With a 1.8° step angle, the motor provides precise positioning and smooth, consistent movement.

Its reinforced internal construction and precision-machined stator design help maintain stable rotation and accurate positioning during operation. The rotor is sealed with high-temperature-cured epoxy resin, helping protect the internal components from machining residue and reducing the risk of jamming during extended use.

The motor delivers stable rotational performance with low operating noise, making it suitable for applications such as CoreXY, Prusa i3, Kossel, Ultimaker, CNC routers, and other motion-control systems.
