Measuring 37 mm (1.46″) in diameter, these 12V and 24V motors are capable of offering huge amounts of torque in a reasonable 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 11 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.
NOTE: Stalling or overloading gearmotors can greatly decrease their lifetimes and even result in immediate damage. Stalls can also result in rapid (potentially on the order of seconds) thermal damage to the motor windings and brushes; a general recommendation for brushed DC motor operation is 25% or less of the stall current.
- Stall Current: 3.1A (24V), 1.6A (12V)
- No-Load Current: <0.08A (12V), <0.11A (24V)
- At Load Current: <0.50A (12V), <0.65A (24V)
