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.

The stainless steel electric vibrators of the NES series are used mainly in the chemical, pharmaceutical and food industries. They serve as drives for conveyor troughs, sieves and discharge devices. The stainless steel surfaces of the vibrators are especially resistant to chemically corrosive environmental conditions and can be thoroughly cleaned manually and by machine with powerful cleaning agents.
Construction and Working Principle
Stainless steel electric external vibrators are threeJphase current asynchronous motors with adjustable unbalances at both ends of the shaft that generate an undirected sinusoidal vibration. The extremely load-resistant roller bearings guarantee a long working life.
