Specification Item Type: Extruder Stepper Motor Kit Material: Hardened Steel, Aluminum Alloy Motor Parameters: Number Of Phases: 2 Phase Resistance: 2.1x(1±10%)Q Holding Torsion: 100mN.M MIN Rotation Direction: ACBDA CW Rotor Inertia: 16g Cm²REF Step Angle: 1.8°±5% Rated Current: DC1.0A/Phase Phase Inductance: 1.6x(1±20%) MH Braking Torsion: 5mN.M REF Insulation Resistance: 100Mohm(DC500V) Insulation Class: Class H 180℃ Motor Wire Length: Approx. 1m / 3.3ft Compatible: 12V And 24V Extruder: Mainly applicable for CR 10, for CR 10S, for Ender 3, for Ender 3 V2 series models. Other models can be designed by yourself according to the size and mounting holes. With this all metal extruder, you can have more choices of consumables when using 3D printers. Also, the larger extrusion wheels increase the grip of the consumables and reduce slippage, and the larger ratio increases torsion to increase the extruder's thrust. The extrusion gear is post treated with a hardening and nickel plating process for wear resistance and good printing results.
