Abstract

The engine has a rotor rotationally mounted about a rotational axis and is provided with a superconductive winding arranged in a winding support. In order to fix the winding support inside an external rotor housing, a rigid connecting device having a hollow cylindrical connecting element made of fiber reinforced plastic is provided on the torque transmitting side. The connecting element is configured as a single piece and consist of end parts located on the front face and a central part located between the latter, wherein the end parts are corrugated in peripheral direction and are non-corrugated in the central part. The end parts of the connecting element are connected to and engine with one another in a non-positive fit manner in groovelike recesses of flangelike end pieces made of metal.
