Product Description
This gearmotor consists of a medium-power, 12 V brushed DC motor combined with a 4.4:1 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: 22×24 / 12×10 = 4.4:1
Key specifications
- voltage: 12 V
- no-load performance:1800 RPM, 80 mA
- stall extrapolation:0.71 kg?cm (10 oz?in), 1.8 A
Dimensions
- Size:25D x 48L mm(Length measurement is from gearbox face plate to back of motor (it does not include the output shaft or motor terminals).)
- Weight:82g
- Shaft diameter:4 mm(D shaft)
General specifications
- Gear ratio: 4.4:1
- No-load speed @ 12V: 1800 rpm(Typical; ±20%)
- No-load current @ 12V: 0.080 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: 1.8 A
- Stall torque @ 12V: 0.71 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: 3.2 W
- No-load speed @ 6V: 900 rpm
- Stall current @ 6V: 0.90 A
- Stall torque @ 6V: 0.36 kg·cm(This motor will run at 6 V but is intended for operation at 12 V.)
- Motor type: 12V, 1.8A stall (MP 12V)
Performance at maximum efficiency
- Max efficiency @ 12V: 47 %
- Speed at max efficiency: 1500 rpm
- Torque at max efficiency: 0.093kg·cm
- Current at max efficiency: 0.26 A
- Output power at max efficiency: 1.5 W
