Feature:1. The motor wire is made of pure copper enameled wire, which is made by winding process.2. The steel is arranged uniformly, the temperature rise of the motor is lower, and there will be no deformation and noise in long‑term transportation.3. Using silicon steel bearing material, strong and durable, has a long service life.4. The surface is coated with imported rotor glue, and the textile silicon steel is oxidized to reduce burrs after grinding.5. Compared with the same period in the industry, the motor torsion is larger, the output is more stable and the noise is lower.Specification:Item Type: 42 Stepper Motor Drive SetNumber of Phases: 2Rated Voltage: DC3.6VPhase Resistance (20℃): 2.4 x (1±15%) π/phaseKeep Torsion: ≥420mN. mSteering (looking at Shaft Extension): A-AB-B-CWMaximum No-Load Operating Frequency: ≥1900 PPSElectric Strength: AC600V/1mA/1SMoment of Inertia: 57.3g. cm²Step Angle: 1.8°±0.09°Rated Current: DC 1.5 A/phasePhase Inductance (1KHz): 3.7×(1±20%) mH/phasePositioning Torsion: 15 mN.m REF.Maximum No-Load Starting Frequency: ≥1500 PPSInsulation Resistance: 100 M2π (DC 500V)Insulation Class: Class BSize: Approx. 23.5mm / 0.9in18mm / 0.7in2mm / 0.1in4.5mm / 0.2in22mm / 0.9in9.4mm / 0.4in42.3mm / 1.7in31mm / 1.2in16.2mm / 0.6in .Package List:1 x Motor 1 x Drive1 x Line
