Due to their fast rise and fall times and superior braking ability, the Jinlong linear resonant actuators (LRA) vibration motors are an excellent choice for haptic applications. Their relatively simple internal construction offers high reliability and exceptionally long life when compared with brushed ERM motors. Jinlong’s LRA have an internal mass that oscillates back and forth along the X-axis at its resonant frequency. They are an excellent alternative to brushless vibration motors as the only internal parts that are subjected to wear / failure are the springs.
