Abstract: An end plate for an electric machine includes: a bearing receptacle in which a magnetic bearing which is configured for rotatably mounting a rotor of the electric machine can be accommodated; and a radially outwardly pointing circumferential contour on which a number of at least three supporting elements are provided, which supporting elements each protrude radially beyond the circumferential contour by a determined protruding amount, with the result that the supporting elements define a discontinuous external circumferential contour of the end plate. The respective protruding amounts of the support elements are dimensioned such that the end plate can be fitted in by making a center of the magnetic bearing correspond to at least one of a geometric longitudinal axis of the electric machine and a magnetic longitudinal axis of the electric machine.

Abstract: A fluid-tight line feedthrough for introducing an electric conductor into a high-pressure chamber includes a housing and an electric conductor that passes through the housing. A ceramic insulator is positioned between the housing and the electric conductor. The ceramic insulator is divided into a first insulator segment facing the electric conductor and a second insulator segment facing the housing, thereby forming a conical separating plane. A fitting made of an electrically conductive material is positioned between the two segments, the fitting being connected to the two segments and to the housing.

Abstract: An electric machine has a housing with an inner circumference; a stator which is inserted into the housing so that an outer circumference of the stator is located opposite the inner circumference of the housing, a clearance fit being formed between the inner circumference of the housing and the outer circumference of the stator; at least one fastening element, each fastening element connects the stator to the housing by positive engagement so that the stator is held at the housing so as to be fixed with respect to rotation relative to it; and a rotor which is rotatably mounted in the housing in a radial direction of the electric machine inwardly of the stator.
