MVE-Exe Increased Safety Range

MVE-Exe Increased Safety Range

Increased Safety MVE-E External Electric Motovibrators consist of an electric motor housed in a sturdy FMEA-designed cast casing, with eccentric weights fitted on both shaft ends. Special design features materials used prevent sparking inside the motor.


Increased Safety MVE-E External Electric Motovibrators can be used as flow aids on hoppers or to improve material discharge, or as drives on machines several purposes such as conveying, screening, sizing, or compacting, in a variety of industries.
When the MVE-E is switched on a sinusoidal centrifugal force is provided by the rotation of the eccentric weights. With only one MVE fitted on a 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.
Specific materials geometry make Increased Safety MVE-E External Electric Motovibrators suitable highly hazardous environments.
