488:1 20.4mm 14 RPM 13 RPM 3.0kg.cm 5.0kg.cm
Note: all reduced no-load speeds have a tolerance of ±15%.

Therefore, choose a lower ratio when your design needs more speed. In contrast, use a higher ratio when slower output and higher torque are more important.

488:1 20.4mm 9 RPM 8 RPM 3.0kg.cm 5.0kg.cm
Note: all reduced no-load speeds have a tolerance of ±15%.

As a result, this version covers both medium-speed and very low-speed applications. Also, compare the rated torque with your actual load before choosing a ratio.

Finally, the 24V DC version provides the highest base motor speed and output power. Therefore, it offers higher gearbox output speeds while keeping the same compact 20mm gear structure.

Ratio Gearbox Length No-load Speed Rated Speed Rated Torque Instant Torque
29:1 15.9mm 340 RPM 300 RPM 0.4kg.cm 3.1kg.cm

488:1 20.4mm 21 RPM 20 RPM 3.0kg.cm 5.0kg.cm
Note: all reduced no-load speeds have a tolerance of ±15%.

In short, select the voltage first. Next, compare the ratio, rated speed, and rated torque to find the right setup for your application.

Related Motor Models & Options

If you require precise step control instead of continuous DC rotation, consider the 20mm Geared Stepper Motor 12V Model NFP-20BY-200. For example, a stepper motor can help with controlled position and angle movement.

If your design needs a smaller gearbox, check the 12mm Spur Metal Gear Motor Model NFP-GM12T-050. Therefore, it can fit projects with tighter space limits.

Finally, for applications that need a larger motor and higher torque, explore the 25mm DC Reduction Gear Motor Model NFP-GM25-BK370.

2 reviews for 20mm 6V 12V 24V Mini Powerful Gear Motor Model NFP-GM20-180SH

  1. Vanshika dubey –

    I was deeply impressed by the performance of the Mini Mighty Gear Motor. Despite its compact size, it delivers plenty of power, and the gear mechanism ensures smooth operation.

  2. David Wilson –

    The high torque brushed dc gear motor worked perfectly for my firearm moving target project, running smoothly on a 6V battery. It’s easy to reverse by simply changing the polarity of the leads, and the motor feels very rugged and durable. I would definitely buy it again!
