This is the motor and encoder portion of our medium-power (HP), 12V 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 specifications:

voltage no-load performance stall extrapolation
12 V 8200 RPM, 100 mA 0.17 kg⋅cm (2.4 oz⋅in), 1.8 A

You can use the following selection boxes to choose from all of our 25D metal gearmotor versions:

General specifications

Gear ratio: 1:12
No-load speed @ 12V: 8200 rpm3
No-load current @ 12V: 0.10 A4
Stall current @ 12V: 1.8 A5
Stall torque @ 12V: 0.17 kg·cm5
Max output power @ 12V: 3.5 W
No-load speed @ 6V: 4100 rpm6
Stall current @ 6V: 0.90 A6
Stall torque @ 6V: 0.085 kg·cm6
Motor type: 12V, 1.8A stall (MP 12V)
Lead length: 8 in7
Encoders?: Y

Notes:

1
Length does not include the motor shaft. See dimension diagram for details.
2
This motor does not have a gearbox.
3
Typical; ±20%.
4
Typical, ±50%; no-load current depends on internal friction, which is affected by many factors, including ambient temperature and duration of motor operation.
5
Stalling is likely to damage the motor. Stall parameters come from a theoretical extrapolation of performance at loads far from stall. As the motor heats up, as happens as it approaches an actual stall, the stall torque and current decrease.
6
This motor will run at 6 V but is intended for operation at 12 V.
7
May vary by a few inches.
