DATASHEET

Direct Current Electric Motor Attributes

First, the NFP-RS-987H series is a large brushed DC motor made for high torque, high speed, and strong power output. It includes several winding options for different voltage and load needs.

Also, the series supports 12V, 24V, and 40V DC systems. Therefore, users can choose a suitable model based on speed, current, torque, and output power.

In addition, the fastest versions reach 20,000RPM at no load. As a result, these motors are suitable for drills, screwdrivers, electric gates, and other high-power drive systems.

Main Product Features

• Wide voltage range: Different models support 12V, 24V, and 40V DC systems.
• High speed: No-load speed ranges from 2,400RPM to 20,000RPM.
• Strong torque: Stall torque reaches up to 13,590g.cm.
• High output power: Maximum efficiency output reaches up to 316.54W.
• Good efficiency: Maximum efficiency reaches up to 77.07%.
• Large motor structure: The motor is suited to higher-load drive systems.
• Simple control: The brushed DC design works with common DC motor controllers.

Motor Performance Data

Next, the table below compares the four NFP-RS-987H motor versions. It shows voltage, speed, current, torque, output power, efficiency, and stall data.

For example, the NFP-RS-987H-3206 provides 20,000RPM at no load. Also, it gives the highest maximum efficiency output at 316.54W.

In addition, this model reaches the highest efficiency at 77.07%. Therefore, it offers a strong balance of speed, torque, and power.

However, the NFP-RS-987H-4157 can draw up to 101.63A at stall. As a result, the power supply, driver, wires, and protection circuit must support very high peak current.

In contrast, the NFP-RS-987H-0573 runs at only 2,400RPM. Therefore, it is better suited to lower-speed applications that do not need extreme RPM.

Large Magnet DC Motor Mechanical Drawing

First, the mechanical drawing shows the motor body, shaft, mounting points, and overall shape. Therefore, users can check the needed installation space before making a bracket or frame.

Also, the large motor structure helps support high torque and higher power. As a result, it can fit demanding drive systems.

Mechanical Design Benefits

• Large motor body: Supports higher power and stronger torque.
• Strong output shaft: Fits gears, pulleys, couplings, and other drive parts.
• Easy mounting: The motor can be fixed with a suitable bracket or frame.
• Several winding choices: Users can select different voltage and speed levels.
• Wide use: Suitable for tools, gates, machines, and custom drive systems.

12V 24V 40V High Power Density DC Motor Profile Diagram

Next, the profile diagram shows how speed, current, torque, power, and efficiency change under load. Therefore, it helps users choose a suitable working point.

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

Finally, the NFP-RS-987H series is suitable for products that need strong torque, high power, and a wide speed range.

• Drills: Provides high speed and strong drive torque.
• Screwdrivers: Supports high-power fastening tools.
• Electric gates: Can drive opening and closing systems.
• Power tools: Fits demanding motor-driven equipment.
• Small machines: Supports rollers, belts, pumps, and other moving parts.
• Custom OEM systems: Suitable for special high-power motor projects.

How to Choose the Correct RS-987H 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 during real use.

Moreover, check stall current when choosing the motor driver and fuse. For example, some versions can draw more than 100A at stall.

In addition, use suitable wires and connectors for the expected current. As a result, voltage drop and excess heat can be reduced.

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

Final Selection Notes

• First, check voltage: Choose the 12V, 24V, or 40V version that matches the power source.
• Next, check speed: Select from 2,400RPM to 20,000RPM.
• 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 need good airflow.
• Furthermore, check mounting: Use a firm 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-987H series is a high-power brushed DC motor family with 12V, 24V, and 40V options.

Therefore, it is well suited for drills, screwdrivers, electric gates, power tools, machines, and other high-load drive systems.
