20mm 6V 12V Reversible High Torque Spur Geared DC Motor NFP-GM20-130SH

9RPM-290RPM 20mm Gear Motor Technical Sheet

First, the 20mm metal gear motor combines a compact size with useful torque and a wide speed range. Therefore, it works well in products where installation space is limited but stable output is still required.

Also, the simple spur gearbox provides smooth and reliable power transfer. In addition, several gear ratios are available, so you can select the right balance of speed and torque for your system.

Key Features

• Compact 20mm design for space-saving installations
• Wide output speed range from 9 RPM to 290 RPM
• 6V DC and 12V DC motor options
• Multiple gear ratios for different speed and torque needs
• Low noise and smooth operation
• Suitable for robots, small machines, tools, and automation systems

Single Motor Technical Data

Next, compare the three motor options below. For example, the first two models operate at 6V DC, while the third model operates at 12V DC. As a result, you can select a version based on your required voltage, speed, current, and power.

Therefore, check the base motor data first. Then, use the gearbox tables below to select the required output speed and torque.

First, this 6V DC version provides output speeds from 9 RPM to 155 RPM. Also, higher ratios reduce the output speed while increasing the available rated torque.

Therefore, choose a lower ratio when speed is more important. In contrast, select a higher ratio when your system needs slower motion and more torque.

Next, this 6V DC version uses a faster base motor. As a result, it provides output speeds from 15 RPM to 240 RPM across the available ratios.

In addition, this version offers more speed than the NFP-GM20-130SH-11340 at the same ratio. Therefore, compare both versions if your project uses a 6V DC supply.

Finally, this version operates at 12V DC and provides the highest output speed of the three options. For example, the 29:1 ratio provides 290 RPM at no load.

In short, the three motor versions provide different speed and power levels. Therefore, confirm the voltage first, and then select the ratio based on your required speed and torque.

Gear Motor with 6mm D Shape Shaft Dimension

The 20mm gear motor uses a 6mm D-shaped output shaft for a secure mechanical connection. Also, its compact gearbox makes it easy to install in small drive systems.

Typical Applications

For example, this 20mm geared motor can support many compact drive systems:

• Robotics: Servo-driven arms, leg actuators, steering systems, and small robot mechanisms.
• Automation: Mini conveyor belts, small actuators, and automated test equipment.
• RC Models: RC cars, planes, drones, and other small moving models.
• Medical Equipment: Automated test equipment and syringe pumps.
• Toys: Dolls, electric trains, and other motorized products.
• Smart Products: Camera shutters, automatic doors, adjustable desks, and small electric fans.
• Power Tools: Compact electric screwdrivers, drills, and similar tools.
