Mve Standard Range

MVE External Electric Motovibrators consist of an electric motor housed in a sturdy FMEA-designed cast casing, with eccentric weights fitted on both shaft ends.

Function:

MVE External Electric Motovibrators can be used as flow aids, on hoppers or silos to improve material discharge, or as drives on vibrating machines for several purposes such as conveying, screening, sizing, or compacting in a variety of industries.
When the MVE is switched on a sinusoidal centrifugal force is provided by rotation of the eccentric weights. With only one MVE fitted on a vibrating machine a rotating force is provided resulting in a circular movement of the machine. Two counter-rotating MVE fitted in parallel on the same machine provide a linear force resulting in a linear movement of the machine. The requirement of circular or linear movement depends on the application.
