Yes, centrifugal drives (e.g. unbalance drives, exciters, shaft drives) via fly weight setting in standstill. Electromagnetic drives via thyristor control unit during operation.
Yes, centrifugal drives via optional frequency converter. No for electromagnetic drives.
Yes, if there is only one drive unit. If there are two drives, normally both drives must work in opposite directions (Exception e.g. spiral elevators).
Yes, all drives are available according to Atex II 3 G+D (zone 2 + 22). Most unbalance motors “JV” are also listed according to Atex II 2 G+D (zone 1 + 21).
Standard unbalance motors “JV” conform to IP 66, unbalance motors “JKA”, electromagnetic and dosing drives IP 65.
Yes, as a major part of the JVM® service we gladly offer assistance with regard to all questions about drive types and drive selection.
All unbalance motors “JV” are infinitely adjustable, the setting can easily be checked on the scale.
Also called construction weight, it is the vibrating weight WITHOUT drive units. E.g. feeder pan or screening machine.
Yes, a control unit is necessary. Direct connection to the electrical network is not possible.
Yes, we have summarised the most important details for you here.
In principle yes. With centrifugal drives, weight differences (only) lead to smaller or bigger amplitudes. With electromagnetic drives differences can damage the vibratory drive.
Yes, centrifugal drives via optional frequency converter with the corresponding input. For electromagnetic drives and the corresponding JVM® thyristor control unit this is standard.
