24mm Small Brushless Vibration Motor – 18mm Type Model NFP-BL2418-SR

Single Round Head Vibration BLDC Motor Parameters

First, the NFP-BL2418-SR is a compact brushless vibration motor with a single round eccentric head. It provides high-frequency vibration, low operating noise, and a large vibration amplitude.

In addition, the motor can work continuously for up to 15,000 hours under suitable operating conditions. Speed regulation, clockwise rotation, and counterclockwise rotation are also available.

Main Product Features

• Long service life: Brushless construction supports up to 15,000 hours of continuous operation.
• Large vibration amplitude: The 13mm round eccentric head generates strong vibration output.
• Low operating noise: Suitable for products that require quiet performance.
• High-frequency vibration: Available with 4,000rpm and 8,000rpm rated speeds.
• Speed control: Pulse-width speed regulation is supported through the control wire.
• Bidirectional rotation: Supports clockwise and counterclockwise operation.

Motor Specifications

Next, the table below lists the main electrical and mechanical specifications of the NFP-BL2418-SR brushless vibration motor.

Note: All reduced no-load speeds have a tolerance of ±15%.

Construction and Performance Features

• Round-shaped vibration head: The large eccentric head is made from high-quality metal. It offers corrosion resistance, stable operation, low heat buildup, and low noise.
• Pure copper coil: The six-wire winding uses 100% pure copper wire. Therefore, it provides stable resistance, fast speed, strong torque, and good high-temperature performance.
• High-quality magnetic tile: The sintered NdFeB magnet uses a three-layer anti-rust treatment. It provides good conductivity, low dynamic loss, and a working temperature range from 80°C to 200°C.
• Built-in brushless driver: The internal control board provides stable plug-and-play operation. It supports forward and reverse rotation, braking, speed regulation, and speed signal output.

Moreover, the brushless design reduces mechanical wear because it does not use carbon brushes. As a result, the motor offers longer service life, lower maintenance, and more stable speed.

Φ24mm Brushless DC Vibration Motor Outline Drawing

First, the outline drawing shows the motor body, shaft, round eccentric head, and wiring position. Therefore, engineers can confirm the required installation space before prototype assembly.

In addition, enough clearance must be left around the rotating eccentric head. This prevents contact with nearby parts during high-speed operation.

Outline Drawing Benefits

• Clear motor dimensions: Helps confirm the Φ24mm body and 30mm total length.
• Eccentric head clearance: Supports safe mechanical layout design.
• Wiring position reference: Makes controller and cable routing easier.
• Compact installation: Suitable for products with limited internal space.
• Prototype support: Simplifies bracket, housing, and mounting design.

Long-Lifetime Brushless DC Motor Wiring Instructions

Forward and Reverse Rotation Control Without Speed Regulation

Next, the wiring diagram shows how to connect the motor for forward and reverse rotation without external speed regulation. Correct polarity and control-wire connection are important for safe operation.

NFP-BL2418 Five-Wire Motor Wiring Instructions

• Red wire: Connect to the positive motor power supply terminal (+). Select the DC supply according to the motor voltage specification.
• Black wire: Connect to the negative motor power supply terminal (-).
• Yellow wire: FG speed signal output. The motor outputs 18 square-wave pulses for each full revolution.
• White wire: PWM speed-control input using a 15kHz to 25kHz signal. When speed control is not required, connect the white wire to the black wire and the motor will run at full speed.
• Orange wire: Forward and reverse rotation control. Connect the orange wire to the black wire to reverse the rotation direction.

Built-In Protection Functions

• Overcurrent protection: Automatic protection starts when instantaneous current exceeds 0.8A.
• Stall protection: The controller stops the motor during a stall condition.
• Restart function: The motor can restart after the power supply is disconnected and reconnected.
• Brushless coil protection: The internal driver helps protect the motor winding and control electronics.

Important: Do not reverse the positive and negative motor power connections.

Also: The yellow wire is the speed signal output wire. It must not be connected to the speed regulator input.

How to Choose This Brushless Vibration Motor

First, select the 12V or 24V version according to the available power supply. Also, choose 4,000rpm or 8,000rpm based on the required vibration frequency and amplitude.

Next, confirm that the controller can provide the required PWM signal when speed regulation is needed. In addition, check whether the product requires forward and reverse rotation.

Moreover, use a rigid mounting structure to transfer vibration efficiently. However, leave enough free space around the round eccentric head and all rotating parts.

Final Selection Notes

• Check rated voltage: Choose 12V DC or 24V DC.
• Check rated speed: Select 4,000rpm or 8,000rpm.
• Check eccentric diameter: Confirm that the 13mm round head fits the product design.
• Check speed-control method: Use a 15kHz to 25kHz PWM signal when regulation is required.
• Check rotation direction: Confirm whether CW, CCW, or both directions are needed.
• Check wiring: Connect all five wires according to their specified functions.
• Check installation space: Allow enough clearance around the round vibration head.
• Test the complete product: Verify vibration, current, temperature, noise, control response, and service life before mass production.

In short, the NFP-BL2418-SR is a compact single round-head brushless vibration motor with long life, low noise, speed control, bidirectional rotation, and strong vibration amplitude. It is suitable for beauty equipment, massagers, personal devices, and other applications requiring reliable brushless vibration performance.
