This is high torque Nema 17 stepper motor with 1.8° 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 30cm long power cable with a 4-pin Harwin female connector already fitted - ready to plug and print!
