Series NEH/NEG High Frequency Electric External Vibrators
Series NEG/NEH high-frequency electric external vibrators were specially developed for concrete compaction on formwork in precast plants and in tunnel construction. A frequency of up to 6,000 min-1 and a robust design help solve the most difficult applications in the construction industry.
Electric external vibrators are unbalance motors according to the short circuit rotor principle. On both ends of the shaft there are adjustable unbalances that generate a sinusoidal vibration at a rate of rotation of the corresponding 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.
Generously dimensioned rolling bearing guarantee high operational safety.

NetterVibration diesel generators series NFG are ideal for powering our electric internal and external vibrators onsite when no electric supply is available. The converter is coupled directly on the Hatz diesel generator. Secondary current 42 V or 250 V available.
The Series FSW converters are ideal with our internal series NCZ, NCZ/S, NCX and NCX/S, as well as external vibrators series NEG and NEH.
