Abstract
The invention relates to a device for determining the center deviation of a shaft () comprising a stator () in which an exciting winding system provided with a number of Perr pole pairs is arranged and two output winding systems provided with respective number of Paus pole pairs, wherein the output winding systems are remotely arranged with respect to each other in the stator, the shaft () is movably placed in the stator () in such a way that it makes it possible to display the shaft center deviation, when ¦Perr−Paus¦=1, an air gap is situated between the stator () and the shaft (), the device voltage source is arranged for supplying the exciting winding system with an alternating voltage and the device output evaluation system is provided for determining the center deviation according to the voltage induced by the output winding systems.
