100:1 Metal Gearmotor 20Dx44L mm 6V CB
These small brushed DC gta5啪啪视频 can deliver a lot of power for their size. This version has a 6V brushed DC motor with long-life carbon brushes combined with a 100:1 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.

- 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.
