Features 1、42 Stepper Motor: The stepper motor with low power, smooth speed, stable performance, low noise and no loss during operation, which ensures the stable operation of the extrusion mechanism. 2、High Torque: 3D printer stepper motor has low self inductive reactance, good responsivenes, longer life and low working temperature. Low loss stators have better high speed performance. 3、Low Resistance: Stepper motor gets low resistanse, thus enables good thermal conductivity. It will work at a safe temperature. Keep your machine running smoothly and quietly with 1.8 degree stepper motor. 4、Low Noise: The internal rotor of stepper motor adopts German tech. 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. 5、Wide Application: This small stepper motors can be used in various area, such as 3D printer, stage lighting, engraving, textile machinery, placement machine, non standard equipment, automation equipment etc. Item Type: 42 Stepper Motor Material: Carbon Steel Phase: 2 Phase Step Angle: 1.8 Degree Rated Current: 1.0A DC Holding Torque: 0.22N.M Min Starting Speed: 600 RPM Operating Speed: 800 RPM Phase Resistance: 3.8Ω±10% Phase Inductance: 3.8mH±10% Rotor Inertia: 24 g.cm² Insulation Resistance: 100mΩ min Insulation Class: Class B Product Size: Approx. 42x23mm / 1.7x0.9in Package List 1 x 42 Stepper Motor 1 x Cable
