Product Description
These small brushed DC gearmotors can deliver a lot of power for their size. This version has a 6V brushed DC motor combined with a 488.3:1 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.
Exact gear ratio:28×25×25×25×25×25×25 / 14×10×10×10×10×10×10 = 488.28125:1
Key specs at 6 V: 30 RPM and 170 mA with no load, 310 oz-in (23 kg-cm) and 2.9 A at stall. (Note: the gearbox torque limit is 70 oz-in (5 kg-cm); see detailed description for important product limitations..)
Dimensions
- Size: 20D × 46L mm
- Weight: 46 g
- Shaft diameter: 4 mm
General specifications
- Gear ratio: 488.28125:1
- No-load speed @ 6V: 30 rpm
- No-load current @ 6V: 170 mA
- Stall current @ 6V: 2.9 A
- Stall torque @ 6V: 310 oz·in(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.)
- Extended motor shaft?: Y
- Motor type: 2.9A stall @ 6V
