GEARED STEPPER MOTORS

Description

  • Permanent magnet
  • Geared stepper motor
  • Unipolar
  • Connector is compatible with the driver header
  • Step angle of 0.088°
  • 117.68 mNm torque
  • VCC input voltage 5V
  • Two included in the kit
  • Easy to use and set up

Small stepper motor with high torque and precision. Ideal for repetitive movements, as in gantries, or for repetitive pan and tilt. It can be useful in stop-motion filming, scanning, plotters… the possibilities are endless. Rated 5v input, but supports 12v chopped supply. With 4096 steps per revolution, you have high precision and repeatability.

Supply voltage +5 VDC
Number of phases 4
DC resistance 50 Ohms ± 7% (25 ℃)
Noise 35 dB (120 Hz, No load,10 cm)
Stride angle 5.625° /64
Coil resistance 50 Ohms
Shaft diameter 5 mm
Step angle 0.088°
Frequency 100 Hz
Diameter 28 mm
Mounting hole spacing 35 mm

Easy to connect with the driver, which has a header-compatible connector. Simply plug it into the driver and upload the included example to your Arduino compatible board, or follow the driver guide to get it rotating.

  1. In this example we are connecting:
    Arduino    Stepper Driver
    D2     —– IN1
    D3     —– IN2
    D4     —– IN3
    D5     —– IN4
    GND —–  –
    Vin    —– +
  2. Download and install the Arduino environment from here or use the web editor.
  3. Connect the stepper motor to the stepper driver.
  4. Power your Arduino with the included power supply by connecting the barrel connector to the board.
  5. Download the Arduino libraries here.
  6. Unzip and paste the folder in the Arduino libraries folder. It’s in the same location as your default sketches. To find the sketchbook location, go to File /Preferences.
  7. Download the sketch here and open, or open the Arduino environment and copy the code into a blank sketch.
  8. Connect your board to your computer with the included USB cable.
  9. Select your board in Tools / Board / Arduino Uno.
  10. Select your port in Tools / Port / COM# (Arduino Uno). This may be slightly different depending on your operating system.
  11. Upload by pressing the arrow in the circle to the upper left.
  12. If everything is OK, the stepper motor should be randomly turning, changing direction and speed like crazy.
