摘要： An electrical machine has a stator with a stator body supporting an electrical stator and a rotor. The rotor is supported by bearing including a radial bearing section forming a radial gas bearing and an axial bearing section forming an axial gas bearing, the stator side parts of these bearing sections being a stator side radial bearing part and a stator side axial bearing part that are rigidly connected to one another and together form a stator bearing structure. The stator side radial bearing part is a bushing, and is radially surrounded by a cooling body. The bushing is connected to the cooling body by an elastic support comprising a thermally conducting filler.

摘要： A rotor for a high-speed electrical machine with gas bearings includes at least one rotor side radial bearing, a rotor side axial bearing, a rotor body section including the at least one rotor side radial bearing, and a rotor end section including the rotor side axial bearing. When seen along the rotor's axis of rotation, a radial bearing section is defined as a section along which a radial bearing extends. Therein, an outer rotor part extends along the rotor end section and the rotor body section. The outer rotor part is shaped to form, in the rotor body section, a hollow cylinder or bearing sleeve. At least one rotor plug is arranged inside the bearing sleeve, and the material of the at least one rotor plug has a CTE lower than 7E-6 K{circumflex over ( )}-1.

摘要： A rotor for a high-speed electrical machine with gas bearings includes at least one rotor side radial bearing, a rotor side axial bearing, a rotor body including the at least one rotor side radial bearing, and a rotor end piece including the rotor side axial bearing. When seen along the rotor's axis of rotation, a radial bearing section is defined as a section along which a radial bearing extends. Therein, the rotor end piece radially surrounds the rotor body at the interface of these two parts.
