37mm Vibration Motor – 57mm Type Model NFP-DH555

RS 555SH DC Motor Model NFP-DH555 Vibration Motor Data Sheet

First, the NFP-DH555 is a powerful RS 555SH DC vibration motor with two fan-shaped eccentric metal heads. This dual-head structure produces stronger vibration than a round eccentric mass of a similar size.

In addition, the motor has an overall length of 90mm. Each vibration head has an outer diameter of 33.5mm and a thickness of 9mm, while the complete motor weighs 280g.

Main Product Features

• Dual-head design: Two metal eccentric heads produce strong and balanced vibration.
• Fan-shaped masses: The fan-shaped structure generates greater vibration than a circular head.
• Multiple voltage options: Available in 6V DC, 12V DC, and 24V DC.
• Multiple speed options: Available with 4,000RPM and 8,000RPM speeds.
• High rated power: Rated output reaches 15W.
• Durable construction: The RS 555SH motor platform supports demanding vibration applications.

Motor Specifications

Next, the table below lists the main electrical, mechanical, and vibration specifications of the NFP-DH555 motor.

Moreover, the dual eccentric heads increase the rotating mass on both sides of the shaft. As a result, the motor can generate powerful vibration for industrial, commercial, and professional equipment.

Miniature Vibration Motors Outline Drawing

First, an eccentric rotating mass motor works like a standard brushed DC motor. Electrical current creates electromagnetic force, which turns the rotor and output shaft.

However, the NFP-DH555 also has two off-center metal masses. When these masses rotate, they create changing centrifugal force and transfer vibration into the mounting structure.

Therefore, the mounting position, head clearance, motor speed, and support rigidity all affect the final vibration strength.

Outline Drawing Benefits

• Clear overall dimensions: Helps users confirm the 90mm total motor length.
• Head size reference: Shows the space required for the 33.5mm eccentric heads.
• Rotation clearance: Helps prevent the metal heads from touching nearby components.
• Mounting guidance: Supports accurate bracket and housing design.
• Faster integration: Simplifies prototype development and mass production planning.

Performance Curve

Next, the performance curve shows the relationship between motor speed, torque, current, efficiency, and output power. Therefore, it helps users select a suitable operating point for the final product.

In addition, the motor should normally operate below its stall condition. Continuous overload can increase current, heat, brush wear, and power supply stress.

Performance Curve Benefits

• Speed evaluation: Shows how rotational speed changes as load increases.
• Current estimation: Helps select a suitable driver, wiring, and power supply.
• Torque comparison: Supports vibration force evaluation under different loads.
• Efficiency analysis: Helps identify a practical continuous operating range.
• Overload protection: Supports current-limit and stall-protection design.

Powerful Vibration Motors Mass Production

Furthermore, the NFP-DH555 can be supplied for prototypes, OEM projects, and mass production. Production control helps maintain consistent motor speed, current, dimensions, and vibration performance.

Mass Production Advantages

• Multiple configurations: Supports 6V, 12V, and 24V voltage options.
• Speed selection: Available with 4,000RPM and 8,000RPM versions.
• Consistent eccentric heads: Controlled head dimensions help maintain vibration output.
• Electrical inspection: Voltage, speed, and current can be checked during production.
• Mechanical inspection: Motor dimensions, shaft alignment, and head installation can be verified.
• OEM support: Suitable for custom equipment and volume production projects.

Applications and Selection Tips

Typical Applications

Finally, the NFP-DH555 is suitable for products that require powerful vibration and a durable dual-head motor structure.

• Industrial vibration equipment
• Massage equipment
• Medical and rehabilitation devices
• Robotic systems
• Arduino vibration projects

How to Choose This RS 555SH Vibration Motor

First, select the 6V, 12V, or 24V version according to the available power supply. Also, choose 4,000RPM or 8,000RPM based on the required vibration strength and acceptable noise level.

Next, confirm that the enclosure has enough space for the motor body and both rotating heads. In addition, leave a safe clearance around each eccentric mass.

Moreover, use a rigid mounting bracket to transfer vibration efficiently. However, the bracket and fasteners must also withstand repeated vibration without loosening.

Final Selection Notes

• Check operating voltage: Choose 6V DC, 12V DC, or 24V DC.
• Check speed: Select 4,000RPM or 8,000RPM according to the required vibration level.
• Check installation space: Confirm the 90mm overall length fits the product.
• Check head clearance: Allow enough room for both 33.5mm eccentric masses.
• Check current capacity: Ensure the power supply and driver support startup and load current.
• Check mounting strength: Use secure fasteners and a rigid motor support.
• Test the complete product: Verify vibration, current, temperature, noise, and service life before mass production.

In short, the NFP-DH555 is a powerful RS 555SH dual-head DC vibration motor with 6V, 12V, and 24V options. Its two fan-shaped metal eccentric heads provide strong vibration for industrial machinery, massage equipment, robotic systems, and other demanding applications.
