24V High-Power (HP) 25D mm Gearmotors
These 25D mm gearmotors have high-power (HP), 24 V motors with a stall current of 2.7 A and a typical free-run current of 100 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 HP 24V motor:

Note: The listed stall torques and currents are theoretical extrapolations; units will typically stall well before these points as the motors heat up. Stalling or overloading gearmotors can greatly decrease their lifetimes and even result in immediate damage. The recommended upper limit for continuously applied loads is 4 kg⋅cm (55 oz⋅in), and the recommended upper limit for intermittently permissible torque is 8 kg⋅cm (110 oz⋅in). 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.
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 our high-power (HP), 24V 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.

| voltage | no-load performance | stall extrapolation |
|---|---|---|
| 24 V | 10,000 RPM, 100 mA | 0.4 kg⋅cm (5.5 oz⋅in), 2.7 A |
