Abstract: The invention relates to a wind turbine with a generator and a method of assembling a generator thereof, wherein the generator comprises a rotor rotatably arranged relative to a stator. The rotor comprises a plurality of superconducting pole units arranged on a back iron which is spaced apart from a rotor structure by a number of thermally insulating plates or beams. Said plates or beams are located between either ends of the rotor and orientated relative to the rotational direction of the rotor. Each plate has a first end firmly connected to another first beam extending in an axial direction and a second end firmly connected to another second beam also extending the axial direction. The first beams are further firmly connected to the back iron while the second beams are further firmly connected to the rotor structure. The thermally insulating plates or beams provide a flexible and cheap support interface that is able to adapt to the tolerances of the individual components.

Abstract: In some embodiments, a system includes a machine segment that includes multiple coils. Each coil is electrically isolated from the other coils in the machine segment, and each coil is electrically coupled to at least one electrical terminal to provide electrical access to the coil. Each electrical terminal provides electrical access to the coil to which it is electrically coupled such that the coil can be removably electrically coupled to an electrical circuit. The machine segment is also configured to be removably mechanically coupled to a second machine segment to form at least a portion of a stator or a portion of a rotor.

Abstract: In some embodiments, a system includes three conductors, each conductor being on a separate layer such that the layers are parallel to one another and stacked. Each conductor has a winding portion and a terminal portion. The conductors are configured such that at least one electrical interconnect electrically couples two adjacent conductors within the winding portion but the third conductor is electrically isolated from the other two conductors within the winding portion. Within the terminal portion all three conductors are electrically coupled.

Abstract: In some embodiments, an electromagnetic machine includes a rotor element configured for movement relative to a stator. The rotor element includes a magnetic support, a magnetic pole assembly, and a retainer. The magnetic support is formed, at least in part, from a ferromagnetic material and is configured to be coupled to the magnetic support. The retainer is coupled to both the magnetic support and the magnetic pole assembly. The retainer is further configured to be in a first state during a first time period and a second state during a second time period, after the first time period, such that during the second time period, the coupling of the magnetic pole assembly to the magnetic support is maintained.

Abstract: In some embodiments, a system includes a conductor on a first layer of a laminated composite assembly. The laminated composite assembly has an input, an output, a first electrical interconnect which couples the conductor on the first layer of the laminated composite assembly with a second conductor on a second layer of the laminated composite assembly, and a second electrical interconnect which electrically couples the first conductor with the second conductor. A width of the second electrical interconnect is greater than a width of the first electrical interconnect. A resistance of the laminated composite assembly as measured between the electrical input and the electrical output is less than the resistance of the laminated composite assembly as measured between the electrical input and the electrical output if the width of the first electrical interconnect were substantially equal to the width of the second electrical interconnect.
