195:1 Metal Gearmotor 20Dx44L mm 12V CB with Extended Motor Shaft
These small brushed DC 男主从小哄骗女主含h 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 195.3:1 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. This version also has a 6 × 2 mm extended motor shaft.
Key specifications:

Notes:
- 1
- Not including output shafts; output shafts add 24 mm to the total length.
- 2
- D shaft.
- 3
- 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.
- 4
- This motor will run at 6 V but is intended for operation at 12 V.
