Selection Notes
First, users should choose voltage and ratio based on speed, torque, current, gearbox length, and available space. Also, users should confirm the final weight because gearbox length changes with the ratio.
- First, for higher speed: Choose a lower ratio such as 3.7:1, 5.2:1, or 14:1.
- In addition, for higher torque: Choose a higher ratio such as 264:1, 369:1, or 515:1.
- Also, for 12V systems: Choose the 12V DC version when the product uses a 12V control board.
- Next, for 24V systems: Choose the 24V DC version when the product uses a 24V power system.
- Moreover, for tight spaces: Check gearbox length before final product design.
- Finally, for long life: Keep the motor within rated load and avoid long stall conditions.
In short, the NFP-28GP-365 low RPM high torque DC gear motor is a good fit for products that need 12V or 24V DC power, ball bearing support, metal planetary gearbox, 6mm shaft, variable RPM, and stable high-torque output.
