Product Description

This gearmotor consists of a low-power, 12 V brushed DC motor combined with a 171.79:1 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: 22×20×22×22×22×22×24 / 12×12×10×10×10×10×10 ? 171.79:1

Key specifications

voltage: 12 V
no-load performance:33 RPM, 50 mA
stall extrapolation:13 kg?cm (180 oz?in), 0.9 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:94 g
Shaft diameter:4 mm(D shaft)

General specifications

Gear ratio: 171.79:1
No-load speed @ 12V: 33 rpm(Typical; ±20%)
No-load current @ 12V: 0.050 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: 0.90 A
Stall torque @ 12V: 13 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.)
Max output power @ 12V: 1.1 W
No-load speed @ 6V: 17 rpm
Stall current @ 6V: 0.45 A
Stall torque @ 6V: 6.5 kg·cm(This motor will run at 6 V but is intended for operation at 12 V.)
Motor type:12V, 0.9A stall (LP 12V)

Performance at maximum efficiency

Max efficiency @ 12V: 31 %
Speed at max efficiency: 28 rpm
Torque at max efficiency: 1.9 kg·cm
Current at max efficiency: 0.14 A
Output power at max efficiency: 0.54 W
