Linear Resonant Actuators | NFPmotor

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.
