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.

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.
