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.

Abstract: One or more embodiments may take the form of a motor having a magnetically-driven mass. In certain embodiments, the mass or masses may be rotated about a connected shaft through axial or radial magnetic flux. Generally, embodiments described herein employ radial or axial magnetic flux to turn one or more magnets affixed to a central shaft, thereby rotating the shaft through the magnet(s') motion to produce a desired output or effect.

Abstract: Described herein are RFID structures and methods of manufacturing RFID structures. An antenna substrate is provided. A first stack layer is provided. An antenna assembly including an antenna track, and at least two contact pads, are formed on a first surface of the antenna substrate. An integrated circuit unit is coupled to the at least two contact pads. A first surface of the first stack layer, the first surface of the antenna substrate, or both are coated with a unidirectional thermally expansive coating material. The first surface of the antenna substrate is positioned to be adjacent to the first surface of the first stack layer.

Abstract: A rotating electrical machine includes a stator, a rotor and at least one active magnetic bearing including a bearing winding, which is an air-gap winding, and includes at least a first phase winding and a second phase winding. A measurement arrangement measures the radial displacement of the rotor by injecting a displacement measurement injected signal into at least one section of at least one of the bearing windings of one of the magnetic bearings, and capturing at least one displacement measurement signal wherein this displacement measurement signal depends on the rotor displacement in a radial direction relative to the stator, this dependency being due to eddy currents in the rotor induced by the displacement measurement injected signal.
