These small brushed DC gearmotors can deliver a lot of power for their size. This version has a 12V brushed DC motor with long-life carbon brushes combined with a 62.5:1 metal spur gearbox. The gearmotor is cylindrical with a diameter of 20 mm, and the D-shaped output shaft is 4 mm in diameter and extends 18 mm from the face plate of the gearbox.

Key specs at 12 V: 225 RPM and 90 mA with no-load, 58 oz-in (4.2 kg-cm) and 1.6 A at stall.

Alternatives available with variations in these parameter(s): gear ratio motor type extended motor shaft? Select variant…

No-load current @ 12V: 90 mA
Stall current @ 12V: 1.6 A1
Stall torque @ 12V: 58 oz·in1
No-load speed @ 6V: 115 rpm2
Stall current @ 6V: 0.8 A2
Stall torque @ 6V: 29 oz·in2
Extended motor shaft?: N
Motor type: 1.6A stall @ 12V CB (carbon brush)

Notes:

1
Stalling is likely to damage the gearmotor. 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.
2
This motor will run at 6 V but is intended for operation at 12 V.
