ELECTRIC MACHINE HAVING A SUPERCONDUCTING ROTOR COIL AND A SUPPORTING DEVICE

摘要

An electric machine is specified having at least one superconducting rotor coil that is mounted in a rotatable manner about a rotation axis and is intended to be cooled, a rotor body and at least one supporting device for supporting the at least one rotor coil with respect to the rotor body. The supporting device comprises an elastically deformable support loop and a stop element, wherein the support loop is designed such that it supports the at least one rotor coil with respect to forces that arise during normal operation of the coil, and in the process prevents contact, imparted via the stop element, between the rotor coil and the rotor body. The support loop is elastically deformable to such an extent that mechanical contact between the rotor coil and the rotor body can occur via the stop element as a result of forces that arise in the event of a fault.
