Awesome Extras
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).
