NFP-GM12-N20VA-HQ 3V 26 Type 0.5W Performance


First, the 3V 26 Type version provides low current and a wide range of output speeds. Therefore, it is useful for small battery-powered motion systems.

Also, lower ratios provide higher speed. In contrast, higher ratios reduce speed and increase output torque.

Note: All reduced no-load speeds have a tolerance of ±15%.

For example, the 10:1 ratio gives the highest no-load speed at 810rpm. However, the 1000:1 ratio gives the lowest speed and the highest stall torque.

Related Motor Models and Options


First, choose the motor type based on the required control method. For example, an encoder version is better when speed or position feedback is needed.

How to Choose the Correct N20 Gear Motor


First, choose 3V, 6V, or 12V based on the available power supply. Next, choose the motor type based on the needed speed, torque, and current.

Also, select a lower ratio when higher speed is required. In contrast, choose a higher ratio when lower speed and stronger torque are more important.

Moreover, compare the rated torque with the normal working load. Therefore, the motor can run without staying close to stall.

Finally, check the stall current before choosing the motor driver and power supply. As a result, the system can better handle startup and short overload conditions.

Important Notes

  1. First, use the correct voltage: Keep the motor within the listed voltage and current range.
  2. Next, handle the motor carefully: Hold the motor case whenever possible.
  3. Also, check polarity: Connect the red lead to positive and the black lead to negative. Reversing polarity changes the rotation direction.
  4. Moreover, avoid long stall operation: Do not block the shaft or keep the motor near stall because excess heat may damage the motor.
  5. In addition, check the load: Keep the normal working load within the rated torque range.
  6. Finally, test the complete system: Check speed, torque, current, heat, noise, and gearbox life before mass production.

In short, the NFP-GM12-N20VA-HQ is a compact 12mm steel gear motor with 3V, 6V, and 12V options and ratios from 10:1 to 1000:1.

Therefore, it is well suited for robots, locks, printers, smart devices, medical equipment, electric tools, actuators, and other compact motion systems.
