Electric External Vibrators
Designs and ambient conditions
Stainless steel vibrators are resistant to very harsh environmental conditions. Especially the chemical, pharmaceuti-
cal and food industries use this resistance in production areas with aggressive, liquid and gaseous media.
ATEX vibrators allow operation in explosive atmospheres (ATEX Zones 1, 2, 21 and 22) using special design
measures in which gases, vapours, mists and dusts are used. These vibrators, which meet very high safety stand-
ards, find a use especially in the chemical and petroleum industry.
Plastic vibrators have the advantages of stainless steel devices, but are much lighter. The useful properties of
these vibrators are used in the manufacture of dairy products (e.g. cheese), throughout the food industry and in
extreme industrial applications.
Information on the NEG, NEA and NED series
Conveying
Sieving
Compacting
Applications
The electric external vibrators of the series
NEG, NEA or NED are always used when,
for example, conveyor troughs or sieves
have to be driven.
In addition, these vibra-
tors can loosen product jams and deposit
build-ups in silos. When used on concrete
formwork, a high surface quality and com-
paction of the concrete is achieved by a
particularly uniform vibration.
One special feature of the NEG is the
maintenance-free operation even under
harsh environmental conditions.
Design and function
External electric vibrators are unbalance
motors based on the short circuit rotor
principle and, apart from a few decisive
differences, are very similar to commercial-
ly available electric motors. The NEG
three-phase vibrators run on 230/400 V,
50 Hz, depending on the number of poles,
at 750, 1.000, 1.500 or 3.000 min
-1
.
The NEA AC units run on 230 V, 50 Hz at
3.000 min
-1
. Further voltages are available.
The NED DC vibrators run on 12 or 24 V at
3.000 min
-1
(NED 601110 only on 24 V,
3.600 min
-1
).
There are unbalances on both shaft ends,
which generate an omnidirectional, sinus-
oidal vibration with the frequency of the
corresponding speed.
All NEG/NEA are also designed for use at
60 Hz, the speed is then correspondingly
20 % higher than the values at 50 Hz. The
unbalance is adjusted, if necessary.
Generously dimensioned roller bearings
guarantee a high degree of operational
safety. All NEG are fully suitable for opera-
tion with Netter frequency converters.
