The high frequency electric external vibrators of the series NEG and NEH
Function
are asynchronous motors with adjustable weights (unbalances) mounted
on their shaft ends.
The NEG/NEH generate circular vibrations, that means the vibrations act
in all directions of a plane.
The frequency can be controlled continuously with the help of frequency
converters.
The centrifugal force can be changed by adjustment of the unbalances.
