ABSTRACT:
An aspect of the invention relates to a machine comprising a rotor mounted so it can rotate about a rotational axis, and a superconductive winding located in a winding support. Further, connection devices are provided to retain the winding support inside a rotor external housing. To compensate changes caused by the expansion of the winding support, a connection device should have at least one connection element that extends axially with one end of the element connected to the winding support in a fixed manner, and the opposite free end connected to a centering retaining element of the rotor eternal housing in a non-positive radial fit, so it can be displaced axially.
