These weights can be adjusted to give different force outputs within the range of the motor but the speed of rotation (frequency) remains constant, unless an external speed controller is used (VFC drive).
2 pole motors are used as flow aids, with 4, 6 and 8 pole motors being most commonly used as drives for various machines.
Vibrating motors from VSS are all IP66.7 rated (except for 5 of the smaller models), with many of the 2 pole models being available in either single or three phase.

Series NEG electric external vibrators are used whenever, for example, conveyor chutes or sieves need to be driven. 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 functioning principle
Electric external vibrators are unbalance motors, and, apart from a few significant differences, are very similar to conventional electric motors. The 3-phase NEG units run at 750, 1000 or VSS provides solutions. 3000 min-1 with a 230/400V, 50Hz power supply, depending on the number of poles.
