{Product included}-1 * NEMA17 Stepper Motor Double Shaft 52Ncm 17HS8401B for 3D Printer.
{Product parameters}-52Ncm (78 oz.in), size: 42 x 42 x 47mm(1.65X1.65X1.85 inches); 1.8 degrees; rated current 1.8 A; wave: double wave; connection cable: 4 pieces; phase: 2; type: hybrid, shaft diameter 5 mm
{Advantages}-1.)High torque, power 15%-20% higher than conventional motors,to achieve the best uniform rotation.2.)The coil is made of 100% pure copper enamel wire, which is made of international cutting-edge technology. 3.) The surface of the rotor is coated with high-quality epoxy resin adhesive to isolate the adsorption burr on the surface of the rotor, the magnetic field is more stable.
{Low noise}-The stepper motor is made of sturdy and durable metal. The perfect combination of rubber and rotor makes the inner structure more stable. This reduces vibrations and noise when the engine is running.
{Note}-The Shaft not same on both sides,Motor front shaft is 5mm diameter shaft and 24mm lenth;Motor back shaft is 5mm diameter and 10mm length..{Product customer service}- every NEMA17 stepper motor has been subjected to strict quality control before leaving the factory.
