DATASHEET

High Voltage Motor 125V DC Motor Data Sheet

First, the NFP-RS-9812H and NFP-RS-9824H are high-voltage brushed DC motors designed for fast speed and strong torque. Both models use a nominal voltage of 125V DC.

Also, both motors support a working voltage range from 90V to 150V DC. Therefore, users can select a model based on speed, current, torque, power, and efficiency needs.

In addition, no-load speed reaches up to 11,000RPM. As a result, these motors are suitable for sewing machines and other high-voltage drive systems.

Main Product Features

• 125V DC operation: Both models use a nominal voltage of 125V DC.
• Wide voltage range: The motors support 90V to 150V DC.
• High speed: No-load speed reaches up to 11,000RPM.
• Strong torque: Stall torque reaches up to 7,670g.cm.
• Useful output power: Maximum efficiency output reaches up to 96.24W.
• Good efficiency: Maximum efficiency reaches up to 73%.
• Brushed DC design: The motor works with a suitable high-voltage DC motor controller.

Motor Performance Data

Next, the table below compares the two 125V motor versions. It shows voltage, speed, current, torque, output power, efficiency, and stall data.

For example, the NFP-RS-9812H-4791 gives the highest no-load speed at 11,000RPM. Also, it provides the highest maximum efficiency output at 96.24W.

Moreover, this model reaches 73% maximum efficiency. Therefore, it offers a good balance of speed, power, and efficiency.

In contrast, the NFP-RS-9824H-9361 gives higher torque at maximum efficiency. As a result, it may be a better choice when working torque is more important than speed.

However, both motors can draw much more current at stall. Therefore, the power supply and motor controller must be sized for the required load.

Large Torque High Speed DC Motor Mechanical Drawing

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

Also, the large motor structure helps support strong torque and high-speed use. As a result, it can fit machines that need steady rotary power.

Mechanical Design Benefits

• Strong motor body: Supports high-speed and high-torque operation.
• Solid output shaft: Fits gears, pulleys, belts, and couplings.
• Easy mounting: The motor can be fixed with a suitable bracket or frame.
• Compact drive source: Provides useful power without a large drive unit.
• Two motor choices: Users can select a model based on speed and torque needs.

Brush Commutated DC Motor Profile Diagram

Next, the profile diagram helps users review the RS-9812H and RS-9824H motor structure. Therefore, it is useful when planning installation and drive-system design.

Also, these motors use a brush and commutator system. As a result, speed control can be handled with a suitable DC motor controller.

Brushed DC Motor Benefits

• Simple drive method: Speed can be controlled with a suitable DC controller.
• Strong starting torque: The motor can provide useful torque during startup.
• Wide speed range: The motor can work across different operating speeds.
• Easy direction control: Rotation can be reversed with a suitable control circuit.
• Replaceable brush system: Carbon brushes can be serviced when required by the motor design.

Applications and Selection Tips

Typical Applications

Finally, these 125V DC motors are suitable for systems that need high speed, useful torque, and a high-voltage DC power source.

• Sewing machines: Provides fast and steady rotary power.
• Textile equipment: Can drive rollers and other moving parts.
• Small machines: Fits compact high-voltage drive systems.
• Automation equipment: Can drive belts, rollers, and mechanical parts.
• Custom machines: Supports special high-speed motor projects.
• OEM equipment: Motor windings and drive systems can be matched to product needs.

How to Choose the Correct 125V DC Motor

First, confirm that the power system can provide 125V DC. Next, compare the required speed and torque with the two motor versions.

Also, choose the NFP-RS-9812H-4791 when higher speed and efficiency are important. In contrast, consider the NFP-RS-9824H-9361 when higher torque at maximum efficiency is preferred.

Moreover, check the normal working current when choosing the power supply. Therefore, the system can support the motor under real load.

In addition, check stall current when selecting the motor controller and protection parts. As a result, the system can better handle short overload conditions.

Finally, avoid keeping the motor stalled. Otherwise, high current can quickly raise heat and damage the motor.

Final Selection Notes

• First, check voltage: Confirm a 90V to 150V DC supply range.
• Next, check speed: Choose between 10,200RPM and 11,000RPM at no load.
• 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 driver and overload protection.
• Then, check insulation: Use wiring and parts rated for the high DC voltage.
• Furthermore, check mounting: Use a firm bracket to keep the motor and shaft aligned.
• Finally, test the full system: Check speed, torque, current, heat, noise, and working life before mass production.

In short, the NFP-RS-9812H and NFP-RS-9824H are 125V brushed DC motors with high speed, strong torque, and useful output power.

Therefore, they are well suited for sewing machines, textile equipment, automation systems, and other high-voltage DC drive applications.
