ITEM NAME:Nema 17 Stepper Motor, 1Pcs Bipolar 1.7A 40Ncm(56.2Oz.In) 40Mm Body 4-Lead M2B7 Nema 17 Stepper Motor, 1Pcs Bipolar 1.7A 40Ncm(56.2Oz.In) 40Mm Body 4-Lead M2B7 1. Uniform speed, no lost step: The enhanced PCB board in the motor and the unique stator technology ensure that the stator gear of the motor is evenly polished, the inner hole has high precision, and the speed is stable and accurate during the working process. 2. The structure is stable and will not be stuck:The surface of the rotor of the motor is coated with imported epoxy resin. The rotor is sealed as a whole and cured by high temperature. The long-term use of the motor is also stable and does not pose a risk of jamming. 3 .The speed is stable and the noise is low: the motor is highly stable by Kossel, Prusa 13, Ultmaker, colexy, etc. The motor has high stability, uniform speed and low noise. WIDE APPLICATION: This small motors can be used in various area, such as stage lighting; laser-engraving; textile machinery; medical equipment; placement machine; non-standard equipment; 3D printer; automation equipment, and etc.. size: 38*42mm HIGH TORQUE: Adopting high quality motor steel material, electric motor kit is provided with high torque (40Ncm(56.2oz.in) ), low self-inductance reactance, responsive and can avoid system error. LOW NOISE: The internal rotor of our stepper motor kit is made with introduced German craftsmanship and there is rotor rubber covering the rotor, effectively reduce the noise.
