Measuring 12 mm (0.47″) in diameter, these 6V motors offer great capabilities in a small package. They are available in a range of gear ratios.
With quadrature encoders added to the micro metal gearmotors (with extended back shaft), these motors use a magnetic disc and hall effect sensors to provide 8 counts per revolution of the motor shaft. The sensors operate from 3.3 V to 5 V and provide digital outputs that can be connected directly to a microcontroller or other digital circuit.
- Stall Current: 0.55A (6V)
- No-Load Current: <0.06A (6V)
- At Load Current: 0.17A (6V)
- Shaft Diameter: 3 mm
