20mm Standard Gear Motor Model NFP-GM20-130SH

6V and 12V Micro Gearhead Motor NFP-GM20-130SH

First, the NFP-GM20-130SH is a compact 20mm standard gear motor for small drive systems. Also, it supports 6V DC and 12V DC motor options.

In addition, each motor version offers a different speed, current, power, and torque level. Therefore, users can select a suitable model for robotics, automation, locks, small machines, and other low-voltage devices.

Moreover, this micro gearhead motor provides reduction ratios from 29:1 to 488:1. As a result, users can choose faster output or stronger low-speed torque based on the final load.

Main Features

• First, 20mm compact metal gearbox: The small gearbox helps save installation space.
• In addition, voltage options: The motor supports 6V DC and 12V DC power systems.
• Also, three motor winding choices: Users can choose different speed, current, and power levels.
• Next, wide ratio range: Reduction ratios from 29:1 to 488:1 support many drive needs.
• Moreover, wide speed range: No-load speeds range from 9rpm to 290rpm.
• Furthermore, high peak torque: The maximum peak torque can reach 5.0kg.cm.

Single Motor Technical Data

First, the table below compares the three motor versions used with this gearbox. Also, it shows the voltage, motor speed, current, output power, and stall data.

Therefore, this table helps users select the correct base motor before choosing a reduction ratio.

In addition, the NFP-130SH-14230 provides higher output than the lower-power NFP-130SH-11340 version. Similarly, the 12V NFP-130SH-11370 offers the highest base motor speed.

As a result, the final geared speed depends on both the selected motor and the selected reduction ratio. Moreover, all reduced no-load speeds have a tolerance of ±15%.

NFP-GM20-130SH-14230 Gear Motor Data

First, this 6V DC version uses the NFP-130SH-14230 motor. Also, it has a 7,200rpm motor speed before reduction.

Therefore, it is suitable when the design needs a good balance of output speed, power, and torque. In addition, lower ratios provide faster output, while higher ratios provide stronger torque.

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

For example, the 29:1 option gives the highest no-load speed at 240rpm. However, the 456:1 and 488:1 options give higher rated torque at a much lower speed.

Therefore, lower ratios suit faster movement, while higher ratios suit slower and stronger movement. In addition, gearbox length rises as more gear stages are added.

6V NFP-130SH-14230 Selection Notes

• First, for higher speed: Choose 29:1, 31:1, 56:1, or 73:1.
• In addition, for balanced output: Choose 107:1 or 182:1 based on the load.
• Also, for higher torque: Choose 268:1, 349:1, 456:1, or 488:1.
• Finally, for space planning: Check the 16mm to 20mm gearbox length before design.

NFP-GM20-130SH-11340 Gear Motor Data

First, this 6V DC version uses the lower-power NFP-130SH-11340 motor. Also, it has a 4,800rpm base speed and lower current use.

Therefore, it can fit systems that need lower power use and smooth low-speed output. Moreover, it is useful for light-duty drive tasks.

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

For example, the 29:1 ratio gives 155rpm with a rated torque of 0.14kg.cm. In comparison, the 488:1 ratio gives 9rpm with a rated torque of 2.1kg.cm.

Furthermore, the high-ratio options reach a maximum peak torque of 5.0kg.cm. However, peak torque should only be used for a short time.

6V NFP-130SH-11340 Selection Notes

• First, for lower current use: Choose this motor when the product needs lower power use.
• In addition, for higher speed: Choose 29:1, 31:1, 56:1, or 73:1.
• Also, for balanced output: Choose 107:1 or 182:1 based on the load.
• Next, for higher torque: Choose 268:1, 349:1, 456:1, or 488:1.
• Finally, for long use: Use rated torque as the better guide for long operating cycles.

NFP-GM20-130SH-11370 Gear Motor Data

First, this 12V DC version uses the NFP-130SH-11370 motor. Also, it has the highest base speed at 8,800rpm.

Therefore, it gives the highest geared output speed among the three motor options. In addition, it is a good choice when the system needs a 12V power supply.

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

For example, the 29:1 ratio gives a no-load speed of 290rpm. Similarly, the 107:1 ratio gives 80rpm with a rated torque of 0.9kg.cm.

Moreover, the 456:1 and 488:1 options provide a rated torque of 3.0kg.cm. As a result, they can support slower loads that need more force.

12V NFP-130SH-11370 Selection Notes

• First, for 12V systems: Choose this version when the product uses a 12V DC supply.
• In addition, for higher speed: Choose 29:1, 31:1, 56:1, or 73:1.
• Also, for balanced output: Choose 107:1 or 182:1 based on the load.
• Next, for higher torque: Choose 268:1, 349:1, 456:1, or 488:1.
• Finally, for stable life: Keep the real working load within the rated torque range.

How to Select a Ratio

First, choose the correct voltage and motor type. Next, select the required output speed.

Also, check the rated torque and gearbox length. Therefore, the final choice should match both the electrical supply and the mechanical load.

1. First, select the required voltage: 6V DC or 12V DC.
2. Next, choose the motor model based on speed, power, and current.
3. Also, select a low ratio for higher speed.
4. In addition, select a high ratio for higher torque and lower speed.
5. Moreover, check the rated torque against the normal load.
6. Then, check the maximum peak torque for short load changes.
7. Finally, confirm the gearbox length fits the product housing.

In short, the 29:1 and 31:1 ratios are best for faster output. In addition, the 182:1 to 488:1 ratios are better for slower and stronger output.

Therefore, users should not select a ratio only by RPM. Also, torque, size, load time, and power supply matter during final selection.
