NEMA17 17HS3401S 42 Stepper Motor 1.5A 38mm 4-Lead Driving System 3D Printer Parts Features: Large torque Imported high-quality motor steel sheet, advanced technology to create bearings, small self-inductance reactance, good responsiveness, It can be operated at a low speed directly with the load link in the near locked-rotor state without gear deceleration. Therefore, a high torque-to-inertia ratio can be generated on a shaft with a large load and reduce systematic errors due to the use of reduction gears. 2. Low noise The internal rotor adopts advanced technology, and the surface is coated with imported rotor gel to prevent burrs on the surface of the silicon steel after oxidative grinding, resulting in increased motor noise. 3. Fine workmanship The whole body is made of high-strength metal, which is sturdy and durable, and has a side-closed metal matte texture to increase friction.
