12V High-Power Carbon Brush (HPCB) Micro Metal Gearmotors
These micro metal gearmotors have high-power, 12 V motors with a stall current of 750 mA and a typical free-run current of 60 mA. They feature long-life carbon brushes and offer the same performance at 12 V as the 6V HPCB offer at 6 V, just with half the current draw. The following table shows all of the versions available with the HPCB 6V motor:

Note: Stalling or overloading gearmotors can greatly decrease their lifetimes and even result in immediate damage. The recommended upper limit for instantaneous torque is 2.5 kg-cm (35 oz-in) for the 380:1 and 1000:1 gearboxes, and 2 kg-cm (25 oz-in) 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.
Versions with other motors are also available. You can use the following selection boxes to choose from all of our micro metal gearmotor versions:
