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). It's ideal for the RepRap Prusa, Mendel 90, Rostock and similar 3D printers, as well as CNC and robotics applications. The motor is supplied with a 1 metre long power cable with a 4-pin Harwin female connector already fitted - ready to plug and print!

Warning:

• As a stepper motor, it should connect to a constant current or chopper driver. Connecting the motor directly to a power supply will destroy the motor.
• To choose a driver, please make sure the driver's output current not higher than motor rated current, and voltage not higher than 36V.
• Please take care of four wires coils order when you connecting to driver, or it will damage your driver.
