Product Description

Description

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 78.13:1 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. This version also has a 6 × 2 mm extended motor shaft.

Exact gear ratio: 28×25×25×25×25 / 14×10×10×10×10 = 78.125:1

Key specifications

voltage: 12 V
no-load performance: 180 RPM, 80 mA
stall extrapolation: 5.4 kg?cm (75 oz?in), 1.6 A

Dimensions

Size: 20D × 44.7L mm(Not including output shafts; output shafts add 24 mm to the total length.)
Weight: 45g
Shaft diameter: 4 mm(D shaft)

General specifications

Gear ratio: 78.125:1
No-load speed @ 12V: 180 rpm
No-load current @ 12V: 0.08 A
Stall current @ 12V: 1.6 A
Stall torque @ 12V: 5.4kg·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: 2.5 W
No-load speed @ 6V: 90 rpm
Stall current @ 6V: 0.8 A
Stall torque @ 6V: 2.7 kg·cm(This motor will run at 6 V but is intended for operation at 12 V.)
Extended motor shaft?: Y
Long-life carbon brushes?: Y
Motor type: 1.6A stall @ 12V CB (carbon brush)

Performance at maximum efficiency

Max efficiency @ 12V: 36 %
Speed at max efficiency: 150 rpm
Torque at max efficiency: 0.93 kg·cm
Current at max efficiency: 0.33 A
Output power at max efficiency: 1.4 W
