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 312.5:1 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: 28×28×28×25×25×25×25 / 14×14×14×10×10×10×10 = 312.5:1
Key specifications
- voltage: 12 V
- no-load performance: 44 RPM, 80 mA
- stall extrapolation: 16 kg⋅cm (220 oz⋅in), 1.6 A
Dimensions
- Size: 20D × 47.7L mm(Not including output shafts; output shafts add 24 mm to the total length.)
- Weight: 47g
-
Shaft diameter: 4 mm(D shaft)
General specifications
- Gear ratio: 312.5:1
- No-load speed @ 12V: 44 rpm
- No-load current @ 12V: 0.08 A
- Stall current @ 12V: 1.6 A
- Stall torque @ 12V: 16 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: 1.8 W
- No-load speed @ 6V: 22 rpm
- Stall current @ 6V: 0.8 A
- Stall torque @ 6V: 8 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
