Netter Electric External Vibrators Series NEG Special Version with Reduced Duty Time Applications Series NEG electric external vibrators are designed for continuous operation with % duty time. In addition, special versions with reduced duty times are available. The reduced duty time aows the use of smaer units possible with the same power output. Design and functioning principle Special vibrators with larger unbalances can be used for intermittent or short-time operation. Despite smaer unit size they deliver the same centrifugal forces as the next housing size up. NEG with reduced duty times are built according to the customer's requirements, to enable individual solutions. Special Version with CC s Applications The special version with CC unbalances are used when two different unbalance settings need to be available during operation. Design and functioning principle In order to use the CC unbalances, a suitable electric switching circuit is required so that the NEG can be operated in both directions. When the NEG rotes in one direction it operates with e.g. maximum unbalance (top picture). When the direction of rotation changes, the outer unbalance disc automaticay turns through a specified angle against the inner unbalance disc, creating a reduced unbalance setting (picture below). The CC unbalances are built according to the customer's requirements and aow a second unbalance setting of -% of the main value. Special Version NEG S in Stainless Steel Applications Series NEG S electric external vibrators can be used wherever the surfaces are subject to particular requirements for chemical resistance. An important feature of the NEG S series is its modular construction. This enables economical production of even the smaest of series in various steel materials. The protection class IP (protection from dust entry and water flooding) aows cleaning with power jets and aggressive cleaning agents. Design and functioning principle A internal components of the stainless steel vibrators come from the established NEG series and are thus production proved. Even the standard version of the NEG S has a surface quality of,3 μm and therefore satisfies the requirements for the chemical and pharmaceutical industries. A higher surface quality can easily be provided if required, e.g. for the food industry. Stainless steel housings are generay heavier than the standard housings. The greater mass must therefore be considered in the layout stage.

In addition, these devices can loosen material blockages and adhesions in silos. When used on concrete forms, the especiay even vibration produces high surface quality and compaction of the concrete. The special feature of the NEG is its maintenance-free operation, even in rough environmental conditions. Design and fonctioning principle Electric external vibrators are unbalance motors, which work according to the short circuit runner principle and, apart from a few significant differences, are very similar to conventional electric motors. The 3-phase NEG units run at 750, 0 or 00 min-1 with a 2/00V, 50 Hz power supply, depending on the number of poles. The NEA single phase units run at 00 min -1 with a 2V, 50 Hz power supply. Additional voltages are available. The direct current NED units run at 00 min -1 with a 12 or 2 Volt power supply. s sitting on each end of the shaft produce an unidirectional sinus-shaped rotation at the frequency of the respective speed of rotation. A NEG/NEA are also designed for operation at 0 Hz. The speed of rotation then lies at 20% above the values at 50 Hz. The unbalance is adjusted if necessary. Generously dimensioned roing bearings guarantee high operational safety. A NEG are suitable for operation with Netter frequency converters, without limitation. Netter provides solutions.
