Applications
The stainless steel electric external vibrators
of the NES series are mainly used in the
chemical, pharmaceutical and food indus-
tries. They serve as drives for conveyors,
sieves and discharge aids. The stainless
steel surfaces of the vibrators are particularly
resistant to chemically aggressive environ-
mental conditions and can be thoroughly
cleaned mechanically and automatically with
powerful cleaning agents.
The extremely resilient roller bearings guaran-
tee a long service life. All NES are suitable for
operation on Netter frequency converters.
Design and function
Stainless steel electric external vibrators are
three-phase asynchronous motors with ad-
justable unbalances on both shaft ends,
which generate a sinusoidal vibration with the
frequency of the corresponding number of ro-
tations.

Applications
The Netter high-frequency electric external vi-
brators of the series NEG/NEH were specially
developed for concrete compaction on form-
work in precast plants and in tunnel construc-
tion. A frequency of up to 6.000 min
-1
and a
robust design help solve the most difficult ap-
plications in the construction industry.
Design and function
Electric external vibrators are unbalance mo-
tors according to the short circuit rotor princi-
ple. On both ends of the shaft there are ad-
justable unbalances that generate a sinusoidal
vibration at a rate of rotation of the corre-
sponding frequency.
The NEG series differs from the NEH series in
its method of mounting.
NEG vibrators are mounted with Netter NBS
fastening kits.
NEH vibrators are fastened with the Netter
quick clamp mounts of the NVH series. This
allows easy transfer of the units.
All NEG/NEH are optimised for operation on
Netter frequency converters and voltage
transformers.

Electric External Vibrators
Special versions
CC Unbalances
Applications
This special version with CC unbalances is
used if two different unbalance settings are
to be at a disposal during operation.
The CC unbalances are manufactured on
customer request and allow a second un-
balance setting of 25-100% of the main
value.
Design and function
To use the CC unbalances, the NEG must
be operable by a corresponding electrical
circuit in both directions of rotation. If the
NEG turns in one direction, it works e.g.
with a maximum unbalance.
When the direction of rotation changes, the
outer unbalance disc automatically rotates
at a specified angle against the inner unbal-
ance disc and thus provides a reduced un-
balance setting.
Shaft Coupling
Applications
This special version with shaft coupling is
used when large centrifugal forces are nec-
essary, but little space is available for in-
stallation.
Design and function
Two or more vibrators in series are operat-
ed with angular synchronous unbalances
by connecting the shafts of the vibrators via
a shaft coupling.
Oil Circulating Lubrication
Applications
This special version with external oil circu-
lating lubrication is recommended when
operating high frequency vibrators continu-
ously, which would lead to major heating
and a reduced bearing life.
Design and function
A hydraulic pump continuously supplies the
bearings with oil during operation, which
flows back into the oil tank via a cooler.
Rotary Encoders
Applications
These special versions with rotary encoders
are always used when the frequency and/or
position of the unbalance is to be detected
electronically. This enables the building of
complex vibration systems.
Design and function
The external electric vibrators are equipped
with a special mounting system for rotary
encoders. Robust rotary encoders with in-
tegrated, highly elastic and a torsionally stiff
hollow shaft coupling measure the frequen-
cy of the vibrator even under the toughest
operating conditions.
Electric External Vibrators
Accessories
Static adjustable frequency converters
ATV 320 / NFU Series
Static adjustable frequency controls
SRF Series
AT V
Applications
The frequency control of the SRF series
and the frequency inverters of the series
ATV and NFU are used to control the fre-
quency of electric vibrators.
Special applications require frequencies
that cannot be achieved with normal multi-
pole vibrators at mains frequency. The spe-
cial feature of this frequency converter is its
robust and uncomplicated design.
Design and function
SRF frequency controllers are mounted in a
control cabinet with a degree of protection
of IP 54. ATV units are frequency converters
in the IP 2x housing and are intended for
switch cabinet installation at the customer.
The performance data correspond to the
SRF series.
NFU units are frequency converters with a
motor circuit in an IP 54 housing for wall
mounting and are equipped with a main
switch, a rotational direction switch and a
setpoint potentiometer.
