VEM vibro-drives generate the oscillation for PEV feeders and for custom designs built around an electromagnetic drive. The lineup splits into two rows: VEM-L1-L4 for light feeders (tray plus material up to a few hundred kilograms) and VEM-T1-T4 for heavy duty, where the largest models handle a tray-plus-material mass of several tonnes.
A drive is sized on a single parameter — the combined mass of the tray and the material on it — which must not exceed the "max. tray mass" figure for the chosen model. Where a drive is already paired with a catalog feeder, that pairing is shown on the model's own page; for a custom design, just check the mass against the table below.
Like the feeders, VEM drives must always run through a control unit — direct mains connection is not allowed. More on control units on the ШУВ / БУВ page.
How is the capacity of an electromagnetic feeder adjusted?
Smoothly, from zero to maximum — by changing the voltage on the drive coil through a control cabinet or unit, with no steps and no process stop.
The control device (a ШУВ cabinet or a БУВ unit) regulates the voltage fed to the electromagnet coil, which directly sets tray oscillation amplitude and therefore feeder capacity. Unlike drives with a mechanical unbalance mass, where adjustment is stepped or requires changing weights, the entire range here — from zero to the rated maximum — is available smoothly, from a single control or a process-control signal, with no feeder stop and no equipment removed. The same property is used for "full-hopper" duty: the feeder switches on and off automatically from a level sensor in the receiving hopper, without an operator.
