Method for operating a magnetically driven vibrating conveying device

摘要

Method for operating a magnetically driven vibrating conveying device (two-mass vibration system) with varying loading by the material being conveyed and constant drive frequency. A high efficiency is achieved without undesired overshooting and with a low control complexity in that the natural frequency without loading by the material being conveyed is selected and set such that, in the event of loading by the material being conveyed, the natural frequency approaches the working frequency with increasing damping and, in the event of maximum loading by the material being conveyed, is approximately equal to the driving frequency. <IMAGE>
