6V Low-Power (LP) 25D mm Gearmotors

These 25D mm gearmotors have low-power (LP), 6 V motors with a stall current of 2.4 A and a typical free-run current of 150 mA. The gearboxes, which are available in a wide range of gear ratios, all have 4 mm diameter, D-shaped output shafts. The following table shows all of the versions available with the LP 6V motor:

Note: Stalling or overloading gearmotors can greatly decrease their lifetimes and even result in immediate damage. For these gearboxes, the recommended upper limit for instantaneous torque is 200 oz-in (15 kg-cm); 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) 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 25D metal gearmotor versions:

This is the motor and encoder portion of the low-power (LP), 6 V versions of our 25D mm metal gearmotors with 48 CPR encoders. It does not include a gearbox, but the pinion gear on the output shaft works with all of our 25D mm gearmotor gearboxes, so this can be used as a replacement motor or encoder for those gearboxes.

Key specs at 6 V: 6200 RPM and 50 mA free-run, 2 oz-in (0.15 kg-cm) and 2.4 A stall.
