NEMA 17 Stepping Motor (62 oz-in 5mm single shaft)

This is about the most powerful NEMA 17 frame size CNC motor you will find. This little bundle of power features 62 oz-in of holding torque. These NEMA 17 stepper motors are perfect for all kinds of small machines like 3D Printers, Laser Cutters and Engravers, and small CNC machines.


This is high torque Nema 17 stepper motor with 1.8 deg. step angle (200 steps/revolution). Each phase draws 2A, allowing for a holding torque of 45Ncm(63.7oz.in). This stepper motor is ideal for the RepRap Prusa, Mendel 90, Rostock and similar 3D printers, as well as CNC and robotics applications. The motors are supplied with a 1 metre long power cable with a 4-pin Harwin female connector already fitted - ready to plug and print!

Make sure the motor connect to a constant current or chopper drive controller before you test motor.
Connecting the motor directly to a power supply will destroy the motor.

Datasheet for the NEMA 17 62 oz-in Stepping (Stepper) Motor

Here is the datasheet for the NEMA 17 62 oz-in stepping motor. If you connect this to a standard bipolar driver, you will not use the yellow or white wires that are at the midpoint of each coil if they exist on the motor that you received. The black wire connects to A+, the green wire connects to A-, the red wire connects to B+ and the blue wire connects to B-.

The motor has a 5mm shaft. Please see image for housing and frame dimensions.
