Vibration Motors – Durable Compact Low-Power

A vibration motor is an electric motor designed to generate vibrations rather than rotational motion. These motors are commonly used in devices that require haptic feedback, alerts, or mechanical vibration for various applications.

Types of Vibration Motors:

Eccentric Rotating Mass (ERM) Motor

1. • Uses an unbalanced mass (eccentric weight) on a rotating shaft to create vibrations.

   • Commonly found in smartphones, game controllers, and pagers.

   • Vibration intensity depends on speed and weight imbalance.

     Linear Resonant Actuator (LRA)

     • Uses a magnetic coil and spring-mass system to produce vibrations in a single direction.

     • More precise and energy-efficient than ERM motors.

     • Used in advanced haptic feedback systems (e.g., Apple’s Taptic Engine).

       Piezoelectric Vibration Motor

       • Uses piezoelectric materials that vibrate when an electric current is applied.

       • High-frequency, precise vibrations (used in some touchscreens and medical devices).

         Coin (or Flat) Vibration Motor

         • Compact design, often used in wearables and small electronics.

         • Can be ERM or LRA-based.

Applications:

• Consumer Electronics: Smartphones, smartwatches, game controllers.

• Industrial Equipment: Vibratory feeders, compactors, sieves.

• Medical Devices: Massage guns, alert systems in hearing aids.

• Automotive: Haptic feedback in touchscreens and steering wheels.

• Accessibility Devices: Alerts for the hearing impaired.

Key Specifications:

• Voltage Rating (e.g., 3V, 5V, 12V)

• Vibration Frequency (Hz)

• Amplitude/Strength (G-force or displacement)

• Size & Form Factor (e.g., 6mm coin motor, cylindrical motor)
