  • Patent number: 11817760
    Abstract: 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.

  • Patent number: 11750058
    Abstract: An electrical machine includes a stator with a stator body supporting an electrical stator and a rotor. The rotor is supported by a bearing having 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 bearing structure is mounted to the other parts of the stator by either the stator side radial or axial bearing part being rigidly mounted to these other parts, and the other bearing part are connected to these other parts by an elastic support or not at all.

  • Patent number: 10707780
    Abstract: A converter having a negative DC terminal and a positive DC terminal; at least three AC terminals, each AC terminal being arranged for an associated AC current to flow through the terminal, a converter bridge with at least three bridge legs, each bridge leg being associated with one of the at least three AC terminals and being able to connect the associated AC terminal to the negative DC terminal or the positive DC terminal; and a current measurement circuit having a current measurement element, the current measurement circuit being configured to guide either none or one or more of the AC currents flowing through one of the at least three AC terminals through the current measurement element.
