This gearmotor consists of a high-power, 12 V brushed DC motor combined with a 74.83:1 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: 22×20×22×22×22×23 / 12×12×10×10×10×10 ? 74.83:1

Key specifications

voltage: 12 V
no-load performance:130 RPM, 250 mA
stall extrapolation:22 kg?cm (310 oz?in), 5.0 A

Dimensions

Size:25D x 54L mm(Length measurement is from gearbox face plate to back of motor (it does not include the output shaft or motor terminals).)
Weight:91g
Shaft diameter:4 mm(D shaft)

General specifications

Gear ratio: 74.83:1
No-load speed @ 12V: 130 rpm(Typical; ±20%)
No-load current @ 12V: 0.25 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: 5.0 A
Stall torque @ 12V: 22 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: 65 rpm
Stall current @ 6V: 2.5 A
Stall torque @ 6V: 11 kg·cm(This motor will run at 6 V but is intended for operation at 12 V.)
Motor type: 12V, 5.0A stall (HP 12V)

Performance at maximum efficiency

Max efficiency @ 12V: 37 %
Speed at max efficiency: 110 rpm
Torque at max efficiency: 3.3 kg·cm
Current at max efficiency: 0.87 A
Output power at max efficiency: 3.9 W
