ELRA motor Germany ELRA model ELRA price

ELRA motors have a set of adjustable eccentric weights installed on each end of the rotor shaft, utilizing the centrifugal force generated by the high-speed rotation of the shaft and eccentric weights to obtain excitation force. Vibration motors have a wide vibration frequency range; only when the excitation force and power are properly matched can mechanical noise be reduced. Vibration motors are classified into six categories, including classification by starting and operating mode, and by operating speed.
