Abstract
An electric machine has a rotor that is rotatable about an axis of rotation, and an especially superconducting winding which is to be cooled to a low temperature. The winding is enveloped by a securing means with a wrap. The outer contour of the wrap of the securing means increases from a smaller outside diameter to a greater outside diameter in the axial direction. The wrap is surrounded in a force-fitting manner by several securing rings which are arranged one behind another and have an inside diameter which conforms to the respective outside diameter of the outer contour.
Claims10
An electric machine, comprising:
- a rotor rotatable about a rotation axis, the rotor comprising a winding to be cooled to a low temperature;
- a securing means surrounding the winding and having a tape wrap, wherein the wrap of the securing means has, as viewed in the axial direction, an outside contour that widens from a smaller outside diameter to a greater outside diameter;
- and
- several sequentially arranged securing rings in force-fitting surrounding relationship to the wrap, wherein the securing rings have each an inside diameter which conforms to the outside diameter of the outside contour of the wrap at a corresponding axial position of the securing ring.
