36mm Brushed DC Motor – 50mm Type Model NFP-RS-540A

High Quality DC Motor Data Sheet

First, the NFP-RS-540A series is a compact brushed DC motor made for stable speed, useful torque, and reliable power output. It includes several winding options for different speed and load needs.

Also, all four versions use a nominal voltage of 12V DC. However, their speed, current, torque, and power levels are different.

Therefore, users can choose the best model based on the required RPM, current draw, torque, and output power.

Main Product Features

• 12V DC operation: All versions use a nominal voltage of 12V DC.
• Wide speed range: No-load speed ranges from 3,000RPM to 16,200RPM.
• Good torque output: Stall torque reaches up to 2,186g.cm.
• Useful power range: Maximum efficiency output reaches up to 44.34W.
• Good efficiency: Maximum efficiency reaches up to 69%.
• Compact structure: The RS-540A size fits many tools, pumps, and small machines.
• Simple control: The brushed DC design is easy to drive with standard DC power control.

Motor Performance Data

Next, the table below compares the four NFP-RS-540A motor versions. It shows voltage, speed, current, torque, output power, efficiency, and stall data.

For example, the NFP-RS-540A-8405 gives the highest no-load speed at 16,200RPM. In addition, it provides the highest maximum efficiency output at 44.34W.

However, the same version also has the highest stall current at 32.55A. Therefore, the power supply and driver must be selected with enough current capacity.

In contrast, the NFP-RS-540A-04222 has the lowest no-load current at 0.11A. As a result, it is useful when lower current is more important than high speed.

Low Noise Micro Electric Motor Dimensions

First, the product image shows the RS-540A motor body, shaft, end cap, and overall form. Therefore, users can check the basic size before making a bracket or housing.

Also, the compact motor body helps save installation space. As a result, it can fit drills, tire pumps, R/C models, and other small drive systems.

Mechanical Design Benefits

• Compact motor size: Fits many tools and small machines.
• Simple output shaft: Makes coupling and gear connection easier.
• Easy mounting: The motor can be fixed with a suitable bracket or frame.
• Several winding choices: Different versions support different speed and torque needs.
• Flexible use: Suitable for pumps, R/C models, tools, and custom drive systems.

DC Permanent Magnet Motor Performance Curve

Next, the performance curve shows how speed, current, torque, power, and efficiency change with load. Therefore, it helps users choose a better working point.

Also, motor current rises when the load becomes heavier. In contrast, speed falls as torque increases.

Performance Curve Benefits

• Speed check: Shows how RPM changes with load.
• Current check: Helps choose the power supply and driver.
• Torque check: Helps match the motor to the load.
• Power check: Shows the useful output power range.
• Efficiency check: Helps find a better point for long-term use.
• Stall check: Helps plan current limits and overload protection.

Applications and Selection Tips

Typical Applications

Finally, the NFP-RS-540A series is suitable for products that need compact size, useful torque, and a wide speed range.

• R/C cars: Provides high speed for model drive systems.
• Drills and screwdrivers: Offers useful torque for compact power tools.
• Tire pumps: Drives small pump systems.
• Robotics: Fits wheels, gears, and custom motion systems.
• DIY machines: Works in many small motor projects.
• Small power tools: Supports compact high-speed drive systems.

How to Choose the Correct RS-540A Motor

First, choose the motor based on the required speed. Next, compare the needed torque and current with the values in the table.

Also, check the working current instead of only the no-load current. Therefore, the power supply can support the motor during real use.

Moreover, check stall current when choosing the driver and fuse. For example, the NFP-RS-540A-8405 can draw up to 32.55A at stall.

Finally, avoid keeping the motor stalled. Otherwise, high current can quickly increase heat and shorten motor life.

Final Selection Notes

• First, check voltage: Make sure the motor matches the power source.
• Next, check speed: Choose from 3,000RPM to 16,200RPM.
• Also, check torque: Match the motor to the normal load.
• Moreover, check current: Size the power supply for real working current.
• In addition, check stall current: Use suitable wiring, driver protection, and a fuse.
• Then, check cooling: Heavy loads may need better airflow.
• Furthermore, check mounting: Use a firm bracket to keep the shaft aligned.
• Finally, test the full system: Check speed, current, torque, heat, noise, and working life before mass production.

In short, the NFP-RS-540A series offers several 12V brushed DC motor versions with different speed, torque, current, and power levels.

Therefore, it is well suited for R/C cars, drills, screwdrivers, tire pumps, robotics, and other compact drive systems.
