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 longterm 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 (115 percent ) or phaseKeep Torsion: 420mN. mSteering (looking at Shaft Extension): A-AB-B-CWMaximum No-Load Operating Frequency: 1900 PPSElectric Strength: AC600V or 1mA or 1SMoment of Inertia: 57.3g. cmStep Angle: 1.80.09Rated Current: DC 1.5 A or phasePhase Inductance (1KHz): 3.7(120 percent ) mH or phasePositioning Torsion: 15 mN.m REF.Maximum No-Load Starting Frequency: 1500 PPSInsulation Resistance: 100 M2 (DC 500V)Insulation Class: Class BSize: Approx. 23.5mm or 0.9in18mm or 0.7in2mm or 0.1in4.5mm or 0.2in22mm or 0.9in9.4mm or 0.4in42.3mm or 1.7in31mm or 1.2in16.2mm or 0.6in .Package List:1 x Motor 1 x Drive1 x Line
