42mm Brushed DC Motor – 53mm Type Model NFP-RS-736H

Brushed DC Electric Motor Key Features

First, the NFP-RS-736H series is a high-power brushed DC motor made for fast speed, strong torque, and heavy load use. It supports several winding options for different voltage and power needs.

Also, the motor series includes 14.4V and 18V DC versions. Therefore, users can choose a model based on the required speed, torque, current, and output power.

In addition, no-load speed reaches up to 24,000RPM. As a result, these motors are well suited for drills, screwdrivers, garden tools, and other high-power drive systems.

Main Product Features

• High speed: No-load speed ranges from 18,600RPM to 24,000RPM.
• Strong torque: Stall torque reaches up to 11,700g.cm.
• High output power: Maximum efficiency output reaches up to 280.64W.
• Good efficiency: Maximum efficiency reaches up to 75%.
• Several voltage options: Models are available for 14.4V and 18V DC systems.
• High-load design: The motor can support demanding tool and machine applications.
• Simple control: The brushed DC design works with common DC motor drivers.

Motor Performance Data

Next, the table below compares the four NFP-RS-736H motor versions. It shows voltage, speed, current, torque, output power, efficiency, and stall data.

For example, the NFP-RS-736H-4158-B provides the highest no-load speed at 24,000RPM. Also, it gives the highest maximum efficiency output at 280.64W.

However, this version also has the highest stall current at 167.31A. Therefore, the power supply, motor driver, wires, and protection circuit must support very high peak current.

In contrast, the NFP-RS-736H-7108 reaches the highest efficiency at 75%. As a result, it offers a strong balance of speed, torque, and power.

Reliable High Torque DC Motor Performance Curve

First, the performance curve shows how motor speed, current, torque, power, and efficiency change as the load increases. Therefore, it helps users choose a suitable working range.

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

Performance Curve Benefits

• Speed check: Shows how RPM changes under load.
• Current check: Helps size the power supply and motor driver.
• Torque check: Helps match the motor to the working 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, fuses, and overload protection.

Applications and Selection Tips

Typical Applications

Next, the NFP-RS-736H series is suitable for products that need high speed, high power, and strong starting torque.

• Drills: Provides fast speed and strong torque for drilling work.
• Screwdrivers: Supports compact electric fastening tools.
• Electric garden tools: Fits cutters, trimmers, and other powered equipment.
• Power tools: Provides strong drive power for demanding jobs.
• DIY machines: Works in custom high-power motor systems.
• Industrial equipment: Can drive pumps, rollers, belts, and other moving parts.

How to Choose the Correct RS-736H Motor

First, choose the motor based on the available supply voltage. Next, compare the required speed and torque with the table above.

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

Moreover, check the stall current when choosing the driver and fuse. For example, some versions can draw more than 160A at stall.

In addition, make sure the wires and connectors can handle high current. As a result, voltage drop and excess heat can be reduced.

Finally, avoid long stall conditions. Otherwise, very high current can quickly raise motor temperature and shorten working life.

Final Selection Notes

• First, check voltage: Choose a 14.4V or 18V version that matches the power source.
• Next, check speed: Select from 18,600RPM to 24,000RPM.
• Also, check torque: Match the motor to the normal mechanical 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: High-power use may require good airflow.
• Furthermore, check mounting: Use a strong bracket to keep the shaft aligned.
• Finally, test the full system: Check speed, torque, current, heat, noise, and working life before mass production.

In short, the NFP-RS-736H series is a high-power brushed DC motor family with fast speed, strong torque, and several winding options.

Therefore, it is well suited for drills, screwdrivers, electric garden tools, power tools, and other high-load motor systems.
