NetterVibration Netter Electric External Vibrators Series NEG Special Version with Reduced Duty Time 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 allows the use of smaller units possible with the same power output. Special vibrators with larger unbalances can be used for intermittent or short-time operation. Despite smaller 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 The special version with CC unbalances are used when two different unbalance settings need to be available during operation. 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. When the direction of rotation changes, the outer unbalance disc automatically turns through a specified angle against the inner unbalance disc, creating a reduced unbalance setting. The CC unbalances are built according to the customer's requirements and allow a second unbalance setting of -% of the main value. Special Version NEG S in Stainless Steel 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 smallest of series in various steel materials. The protection class IP (protection from dust entry and water flooding) allows cleaning with power jets and aggressive cleaning agents. All 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 generally heavier than the standard housings. The greater mass must therefore be considered in the layout stage.
NetterVibration Netter Frequency Converter Series NFU Series NFU frequency converters are used to regulate the frequency of series NEG electric external vibrators. Certain applications require frequencies which cannot be achieved with the normal multiplepoled external vibrators at mains frequency. The special feature of this frequency converter is its robust and simple construction. The fully equipped units are designed for wall-mounting. Low-loss power electronics make operation with high tolerance input voltages possible. The frequency converters produce constant 3-phase voltages at frequencies of 0.5 Hz to Hz, making rotational speeds of to 7 rpm/min. possible with a 2-pole NEG. This enables easy adjustment of the rotational speed. kw/a Supply Voltage Protection Class NFU 1-002/1,5 NFU 1-00/3,3 NFU 1-00/3,7 NFU 1-007/,2 NFU 1-0/, NFU 1-015/ NFU 1-022/ NFU 2-00/1,5 NFU 2-00/1, NFU 2-007/2,3 NFU 2-0/3 NFU 2-015/,1 NFU 2-022/5,5 NFU 2-0/7,1 NFU 2-00/,5 0,1/1,5 0,37/3,3 0,55/3,7 /,2 1,1/, 1,5/,0 / 0,37/1,5 0,55/1, /2,3 1,1/ 1,5/,1 /5,5 /7,1,0/,5 1~: 0 to 2 V, 50/ Hz 1~: 0 to 2 V, 50/ Hz 1~: 0 to 2 V, 50/ Hz 1~: 0 to 2 V, 50/ Hz 1~: 0 to 2 V, 50/ Hz 1~: 0 to 2 V, 50/ Hz 1~: 0 to 2 V, 50/ Hz 3~: 323 to 550 V, 50/ Hz 3~: 323 to 550 V, 50/ Hz 3~: 323 to 550 V, 50/ Hz 3~: 323 to 550 V, 50/ Hz 3~: 323 to 550 V, 50/ Hz 3~: 323 to 550 V, 50/ Hz 3~: 323 to 550 V, 50/ Hz 3~: 323 to 550 V, 50/ Hz The permissible temperature range lies between 0 C and +0 C. The use of a braking resistance allows rapid braking within a few revolutions after switching off the supply voltage, in order to avoid undesired resonance vibrations. Ohm/Watt Protection Class BZ / / IP 5 Netter Braking Devices Series BZ Series BZ braking devices are used to bring the running NEG to a standstill, as quickly as possible. It is often necessary to be able to switch off vibrating tables and conveyors without them running on, in order to avoid the symptoms of resonance.

Please consult us, we will help you with your layout! 5 kw/5,5 kw kw/ kw 2 kw/2 kw A special feature of these devices is a very high braking efficiency with compact unit size. Upon activation the load-resistant power electronics change the direction of the electric rotational field, thus bringing the NEG to an immediate standstill. The momentarily high braking currents are easily tolerated by the NEG. The permissible temperature range lies between 0 C and +0 C. These braking devices are only suitable for constant mains frequencies of 50Hz or Hz. Operation together with a frequency converter is not permitted. 7

In addition, these devices can loosen material blockages and adhesions in silos. When used on concrete forms, the especially 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 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. All are also designed for operation at Hz. The speed of rotation then lies at 20% above the values at 50 Hz. The unbalance is adjusted if necessary. Generously dimensioned rolling bearings guarantee high operational safety. All NEG are suitable for operation with Netter frequency converters, without limitation. Netter provides solutions.
