Electric vibrators consist of a specially designed motor with out-of-balance weights attached to shafts extending from each end of the rotor. 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.
