12mm Small Vibration Motor – 15mm Type Model NFP-N20VAZ-09200-30

3.7V Double Heads N20 Micro Vibration Motors Data Sheet

First, the NFP-N20VAZ-09200-30 is a 3.7V double-head N20 micro vibration motor. Its dual eccentric masses provide balanced and strong vibration output for compact electronic devices.

In addition, the small motor body is suitable for products with limited installation space. Therefore, it can provide effective vibration feedback without requiring a large mounting area.

Main Product Features

• Dual-head vibration: Two eccentric masses provide balanced and powerful vibration performance.
• Compact design: The small motor body fits space-limited product structures.
• Reliable 3.7V operation: The motor is optimized for low-voltage devices and stable performance.
• Strong vibration output: The rated amplitude reaches 15G under the listed test conditions.
• Low starting voltage: The motor can start at ≤1.2V DC under suitable conditions.
• Durable construction: The motor supports consistent operation in daily-use products.

Motor Specifications

Next, the table below lists the main electrical and performance data. Users should compare these values with the power supply, driver circuit, and actual product load before testing.

Moreover, the motor reaches a rated load speed of 8,000rpm ±12%. As a result, it can provide noticeable vibration while maintaining a compact structure.

However, the power circuit should safely support the rated load current and stall current. Proper current capacity helps the motor start reliably and protects the electronic components.

Double Heads Electric Vibrating Motor Outline Drawing

First, the outline drawing shows the body dimensions, dual eccentric masses, lead wires, and required installation space. Therefore, designers can use it to plan the motor position before sample assembly.

In addition, enough clearance should be left around both rotating masses. This prevents the masses from touching the housing or other internal components during operation.

Dual Eccentric Mass Design

The dual-head structure distributes vibration across both sides of the motor shaft. As a result, it can provide more balanced vibration than a typical single-head ERM motor.

• Balanced vibration: Two eccentric masses help distribute vibration more evenly.
• Strong feedback: The dual-mass design supports clear tactile or mechanical feedback.
• Compact integration: The N20 motor body fits many handheld and wearable devices.
• Flexible mounting: The motor can be installed in different product layouts when enough clearance is available.
• Stable operation: Secure mounting helps reduce unwanted movement and noise.

Installation Notes

First, mount the motor firmly to prevent the body from shifting during operation. Also, avoid applying excessive pressure to the motor housing or shaft.

Next, check that both eccentric masses can rotate freely. Any contact with the product housing may increase noise, current, wear, or vibration imbalance.

Finally, test the motor inside the actual enclosure. The product material, mounting method, and internal structure can change the final vibration strength and sound.

Applications and Selection Tips

Typical Applications

This double-head micro vibration motor is suitable for devices that need compact size and strong vibration feedback. For example, it can be used in wearable electronics, medical instruments, handheld tools, and smart controllers.

• Wearable devices: Provides vibration alerts and user feedback in compact products.
• Medical equipment: Supports vibration functions in portable instruments and diagnostic tools.
• Fitness trackers: Provides notification and activity feedback.
• Handheld tools: Produces clear vibration signals in compact equipment.
• Smart controllers: Adds tactile feedback to buttons, triggers, or control functions.
• Consumer electronics: Supports alarms, notifications, and interactive vibration effects.

How to Choose This Vibration Motor

First, confirm that the product uses a 3.7V DC power supply. Also, check that the driver circuit can support a rated load current of ≤260mA.

In addition, the circuit should safely handle a stall current of ≤500mA. Therefore, suitable current protection and motor control should be included in the final design.

Next, confirm that the product has enough space for the motor and both eccentric masses. The rotating parts must remain clear of wires, housings, and nearby components.

Moreover, compare the 15G amplitude with the required vibration effect. The final result may vary with mounting position, enclosure material, product weight, and operating voltage.

Final Selection Notes

• Check voltage: Use 3.7V DC as the rated operating voltage.
• Check rated current: Confirm that the power supply can support ≤260mA.
• Check stall current: Make sure the driver can safely handle ≤500mA.
• Check speed: Confirm that 8,000rpm ±12% meets the application requirement.
• Check vibration strength: Evaluate whether the 15G amplitude suits the product.
• Check rotating clearance: Leave enough space around both eccentric masses.
• Test the complete product: Verify vibration, current, noise, heat, and service life before mass production.

In short, the NFP-N20VAZ-09200-30 is a compact 3.7V dual-mass ERM vibration motor. It combines balanced vibration, 15G amplitude, low starting voltage, and a small N20 motor body for wearable, medical, handheld, and smart electronic devices.
