Micro Metal Gearmotors

With a cross section measuring only 10 × 12 mm (0.39″ × 0.47″), these small brushed DC gearmotors are available in a wide range of gear ratios—from 5:1 up to 1000:1—and with five different motors: high-power 6 V and 12 V motors with long-life carbon brushes (HPCB), and high-power (HP), medium power (MP), and low power (LP) 6 V motors with shorter-life precious metal brushes. With the exception of the 1000:1 gear ratio versions, all of the micro metal gearmotors have the same physical dimensions (though the terminal size and separation on the HPCB versions differ slightly from the other versions), so it is generally easy to swap one version for another if your design requirements change. Versions of these gearmotors are also available with an optional extended motor shaft, which allows for the addition of encoders like our magnetic encoder pair kit.

Note: Stalling or overloading gearmotors can greatly decrease their lifetimes and even result in immediate damage. The recommended upper limit for instantaneous torque is 35 oz-in (2.5 kg-cm) for the 1000:1 gearboxes and 25 oz-in (2 kg*cm) for all the other gear ratios; we strongly advise keeping applied loads well under this limit. Stalls can also result in rapid (potentially on the order of seconds) thermal damage to the motor windings and brushes, especially for the versions that use high-power (HP and HPCB) motors; a general recommendation for brushed DC motor operation is 25% or less of the stall current.

Subcategories

These low-power (LP), 6 V micro metal gearmotors have a stall current of 360 mA at 6 V and a typical free run current of 40 mA.

These medium-power (MP), 6 V micro metal gearmotors have a stall current of 700 mA at 6 V and a typical free run current of 40 mA.

These high-power (HP), 6 V micro metal gearmotors have a stall current of 1.6 A at 6 V and a typical free run current of 120 mA.

These high-power (HPCB), 6 V micro metal gearmotors have a stall current of 1.6 A at 6 V and a typical free run current of 120 mA. They use the same motors as the HP versions, but they feature long-life carbon brushes instead of precious metal brushes.

These high-power (HPCB), 12 V micro metal gearmotors have a stall current of 800 mA at 12 V and a typical free run current of 100 mA. They feature long-life carbon brushes and offer the same performance at 12 V as the 6V HPCB versions offer at 6 V, just with half the current draw.

This category contains all of our micro metal gearmotors with extended motor shafts, which allow for the addition of encoders.
