This NEMA 17 Stepper Motor is a bi-polar 2.5A motor with a 4.8kg.cm holding torque that is capable of high torque and high accuracy, with a step angle of 1.8° and a total step per revolution count of 200. It is designed for precision rotation when used in conjunction with Stepper Motor Drivers, and as such is commonly used within machines like 3D Printers, CNC machines, as well as wide range of other light manufacturing equipment.

This stepper motor operates on 3.1V at 2.5A per phase, with an impressive holding torque and a relatively strong detent torque. These features, as well as many more, are all packed into a tiny 43x43x48mm package that weighs just under 350grams, making it ideal to install on the axes of machines like 3D printers without causing too much extra strain on the frame.

Typical Applications for the NEMA 17 Stepper Motor (2.5A , 4.8kg-cm):

Although this NEMA 17 Stepper Motor can be used for almost any application that can benefit from the transfer of rotational force into linear motion, we stock these Motors specifically for 3D Printers. This is because they provide the ideal holding and detent torque for moving Extruder Assemblies and Hotend Assemblies along the various axes, while the 200 steps per revolution helps to ensure optimal accuracy throughout the printing process.

And as a final note, these Stepper Motors also feature four mounting points on the top of each unit, which can be used to install Damper Pads, which reduce vibration and keep the shaft of the motor as straight as possible. This prevents any unnecessary damage and reduces the effects of any wobble or tension that the axis may be exposed to.
