Precision Haptic Vibration Motors Are Used In Many Haptic Applications. Linear Resonant Actuator Is Long Lifetime When Compared With ERM Vibration Motors.
8mm LRA Linear Resonant Actuator Provides Powerful Haptic Buzz
An 8mm LRA linear resonant actuator is a precision vibration motor. It produces an oscillating force on one axis.
Unlike a DC eccentric rotating mass (ERM) motor, a linear vibration motor uses AC voltage. The voltage drives a voice coil against a moving mass that connects to a spring.
Key Haptic Feedback Features
- High-Precision Haptic Feedback: Provides accurate and fast response for consumer electronics.
- Optimized Frequency Performance: Offers 205Hz and 235Hz options for different device needs.
- Ultra-Compact 8mm Design: Fits wearables, VR controllers, and compact mobile devices.
- Energy-Efficient Operation: Low power use helps extend battery life in portable products.
- Durable and Reliable: Supports long-term use in demanding products, including medical haptic feedback systems.
First, drive the voice coil at the spring resonant frequency. As a result, the full actuator vibrates with a perceptible force.
You can change frequency and amplitude through the AC input. However, the actuator must run at its resonant frequency to create meaningful force with high current.
205Hz Linear Resonant Actuator Performance
Next, review the 205Hz Linear Resonant Actuator (LRA) data. This compact vibration motor fits wearable devices, smartphones, and other products that need tactile alerts and z-axis vibration.
