This gearmotor consists of a medium-power, 12 V brushed DC motor combined with a 226.76:1 metal spur gearbox. The gearmotor is cylindrical, with a diameter just under 25 mm, and the D-shaped output shaft is 4 mm in diameter and extends 12.5 mm from the face plate of the gearbox. This gearmotor is also available with an integrated encoder.

Exact gear ratio: 22×22×22×22×22×22×24 / 12×10×10×10×10×10×10 ? 226.76:1

Key specifications

voltage: 12 V
no-load performance: 35 RPM, 80 mA
stall extrapolation: 24 kg?cm (330 oz?in), 1.8 A

Dimensions

Size:25D x 56L mm(Length measurement is from gearbox face plate to back of motor (it does not include the output shaft or motor terminals).)
Weight:94g
Shaft diameter:4 mm(D shaft)

General specifications

Gear ratio: 226.76:1
No-load speed @ 12V: 35 rpm(Typical; ±20%)
No-load current @ 12V: 0.080 A(Typical, ±50%; no-load current depends on internal friction, which is affected by many factors, including ambient temperature and duration of motor operation.)
Stall current @ 12V: 1.8 A
Stall torque @ 12V: 24 kg·cm(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.)
No-load speed @ 6V: 18 rpm
Stall current @ 6V: 0.90 A
Stall torque @ 6V: 12 kg·cm(This motor will run at 6 V but is intended for operation at 12 V.)
Motor type: 12V, 1.8A stall (MP 12V)

Performance at maximum efficiency

Max efficiency @ 12V: 32 %
Speed at max efficiency: 30 rpm
Torque at max efficiency: 3.6 kg·cm
Current at max efficiency: 0.28 A
Output power at max efficiency: 1.1 W
