Model: NFP-GM20-180, 6V DC
First, the 6V DC version is a good choice for low-voltage control systems. Also, the table below lists each ratio with no-load speed and rated load data.
Therefore, users can choose a low ratio for speed. In addition, users can choose a high ratio for stronger low-speed output.

Note: All reduced no-load speeds have a tolerance of ±15%.
Therefore, the 12V DC model is a good fit for products that need more speed. In addition, high ratios can still give strong low-speed torque.
Model: NFP-GM20-180, 24V DC
Furthermore, the 24V DC version works well in systems with a higher supply voltage. Also, it keeps low current while giving useful torque through the metal gearbox.
Similarly, the 24V DC model supports many ratio choices for speed control. In conclusion, it is a practical option for compact tools and small drive units.

Used these metal gear motors for my wheel models. They are a little more powerful than I need, but that’s not a bad thing, the model does not need to be very accurate. Happy with how they turned out.😶🌫️
