8mm LRA Linear Resonant Actuator Provide Powerful B Haptics Buzz


A linear resonant actuator is a precision vibration motor that produces an oscillating force across a single axis. Unlike a DC eccentric rotating mass (ERM) motor, a linear vibration motor relies on an AC voltage to drive a voice coil pressed against a moving mass that is connected to a spring.

When the voice coil is driven at the resonant frequency of the spring, the entire actuator vibrates with a perceptible force. Although the frequency and amplitude of a linear resonant actuator may be adjusted by changing the AC input, the actuator must be driven at its resonant frequency to generate a meaningful amount of force for a large current.

To provide the most realistic feedback using eccentric rotating masses (ERMs) or linear resonance actuators (LRAs), you will need a device that implements advanced haptic effects. Replacement of NFP's LRA MOTOR Y-AXIS, G0832012.

This 8mm diameter LRA can be driven by TI's DRV2605L haptic driver. This kind of linear actuator will really get you buzzing! The powerful haptic buzz is programmable with a range of built-in patterns, or you can program your own. This little haptic driver and actuator are great for adding some buzzy feedback to your projects.

    I am using these linear motors with 3rd and 4th graders to build vibrating insect models. They seem to be doing the job very well. Strong enough vibration, and create more vibration when set on edge instead of flat.
