A powerful bipolar (4-wire) NEMA17 stepper motor with 200 steps per revolution (1.8 degrees per step). This is one of the most powerful NEMA17 motors, with a holding torque of 5300 g·cm (0.52 N·m, 74 oz·in). It has a current rating of 1.7 A per phase, which is ideal for small drivers such as Allegro A4983 and A4988, and Texas Instruments DRV8811, DRV8818 and DRV8825, as found on Pololu and StepStick driver modules, and on boards such as grblShield and TinyG. It also works very well with larger drivers, such as those based on the TB6560 and TB6600 chips. This is our highest-torque NEMA17 motor, and it's an excellent match for the ShapeOko and eShapeOko. We also stock a 0.9° motor of the same size, a smaller and lighter 1.8° motor, and a motor of the same size but lower impedance.
