Feature:1. The output part adopts a screw rod with a pitch of 0.4mm, and the rotation is turned into thrust through the nut pair matched with the screw rod.2. Using sophisticated production technology, the accuracy is higher when using subdivision drive control to achieve the purpose of precise control.3. This basic step angle of the motor is 18 degrees, and the displacement resolution can be up to 0.02mm.4. Small in size, light in weight, easy to carry, can be carried around, easy to control and convenient to use.5. Widely used in cameras, optical instruments, lenses, accuracy equipment, automatic door locks and other fields.Specification:Item Type: Stepper MotorDrive Voltage: 3VIntroducing Torsion: 3.0 gf-cm min (AT 500 PPS, 3.0V DC)Pull-out Torsion: 3.8 gf-cm min (AT 500 PPS, 3.0V DC)Rated Current: 0.2ARated Speed: 3000RPMScrew Length: Approx. 32.4mm / 1.3inSlider Stroke: Approx. 26.5mm / 1.0inMotor Diameter: Approx. 10mm / 0.4inScrew Diameter: 2Screw Pitch: Approx. 0.4mm / 0.02inStep Angle: 18Phase Resistance: 15.Package List:1 xStepper MotorNote:Note that it is a stepper motor, it will not turn when directly connected to the electricity, it needs a stepper motor drive board and a control board
