NEMA 17 motors are in many robotics applications from CNC machines to medical instruments, however in the maker world, we commonly see them being used in 3D printers.

We stock a range of NEMA 17 motors to ensure you have a suitable selection to choose from for your specific application, whether the focus is on weight, size or technical characteristics.

This particular motor is a NEMA 17 42mm motor with a 40mm tall body (42/40), D-shape shaft and cable connector. Full specifications and dimensions can be found below, along with a datasheet.

A short cable is included but please check the order of the wires as they may not match your intended application (for example, some 3D printer mainboards may require a different wire order).
