【Packing List】 3pcs Nema 17 Stepper Motors 42x48mm, 3pcs 31.5in(0.8Meter) Cable.
【 Parameters】 NEMA 17 bipolar 1.65"x1.65"x1.85" 4-wire，Step Angle 1.8°，rated current 1.7A and phase resistance: 1.8ohms，Static torque 0.56Nm.Double shaft with knob.The shaft length is 20 mm, the D port shaft diameter is 4.5 mm, and the round port shaft diameter is 5 mm.
【New Design】 Our stepper motor is equipped with a knob to help you adjust the axis more accurately, flexibly, and intuitively to improve work efficiency and make axis control easier and faster.
【High Torgue and Low Noise】 Low self-inductive reactance, good responsivenes, longer life and low working temperature.And the surface is coated with imported rotor glue to prevent the burr on the surface caused by the oxidative grinding of carbon steel that cause the motor noise.
【Warranty】 All stepper motor passed QC before shipment. But if you have problem, we still provide free return/exchange in 90 days, pls contact us.
