How To Select The Proper Vibrating Feeder Design ...

Since this design has the twin vibrators synchronizing to produce linear force, these feeders do not stop shaking immediately after power is turned off as the eccentric weights coast to a stop. A VFD with dynamic braking or a starter with a dynamic brake will end the vibration much more quickly to limit the erratic motion at shut down.
