Features: <br>1. The speed is even and does not lose steps. <br>2. The PCB board is reinforced to the motor, and the unique stator technology is adopted to ensure that the stator teeth of the motor are evenly polished, the inner hole has high precision, and the rotation speed is stable and accurate during the working process. <br>3. The structure is stable and works smoothly. <br>4. The surface of the rotor of the motor is coated with imported epoxy resin to prevent the motor from generating noise due to burrs on the surface of the carbon steel after oxidative grinding. <br>5. The speed is stable and the noise is low. <br>6. The motor has high stability, high speed and low noise through KOSS ELISA, PRUSA I3, ULTMAKER, COREXY and other motors. <br> <br>Specifications: <br>Number of phases: 2 <br>Rated voltage: DC 3V <br>Phase resistance (20 ° C): 2.0 x (1 ± 20%) Ω / phase <br>Holding torque: ≥ 480mN.m <br>Steering (shaft extension): A-ABB-clockwise <br>Maximum no-load operating frequency: ≥ 1900PS <br>Electrical strength: AC600V /1MA/IS <br>Moment of inertia: 87.3g.cm2 <br>Step angle: 1.8 ° ± 0.09 ° <br>Phase rated current: Dc1.5A / phase <br>Inductance: (IKHz) 4.9 x (1 ± 20%) m / phase <br>Positioning torque: 20 mn.m REF. <br>Maximum no-load starting frequency: ≥1600PPS <br>Insulation resistance: ≥100MΩ (DC 500V) <br>Insulation class: Class B <br>Quality: 312g REF <br> <br>Package List: <br>1 * Stepper Motor <br>1 * Connecting Cable1、The speed is even and does not lose steps. <br>2、The PCB board is reinforced to the motor, and the unique stator technology is adopted to ensure that the stator teeth of the motor are evenly polished, the inner hole has high precision, and the rotation speed is stable and accurate during the working pr <br>3、The structure is stable and works smoothly. <br>4、The surface of the rotor of the motor is coated with imported epoxy resin to prevent the motor from generating noise due to burrs on the surface of the carbon steel after oxidative grinding. <br>5、The speed is stable and the noise is low.
