These small brushed DC gearmotors can deliver a lot of power for their size. This version has a 6V brushed DC motor combined with a 195.3:1 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 6 V: 73 RPM and 170 mA with no load, 130 oz-in (9.5 kg-cm) and 2.9 A at stall. Note: the gearbox torque limit is 70 oz-in (5 kg-cm); see detailed description for important product limitations.

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.
