The coil winding has an electrical conductor for an electrical machine and includes at least two layers. The electrical conductor, following its longitudinal extension, runs inwardly wound in a first of the at least two layers, and then extends to a second of the at least two layers and runs outwardly wound in the second layer. The electrical machine includes at least one such coil winding. The hybrid electric aircraft is in particular an airplane and includes such an electrical machine and/or at least one such coil winding.

The invention relates to a rotating electrical flux-switching machine, comprising a rotatable tubular rotor (), an inner first stator (), and an outer second stator () that is concentric and spaced apart relative to the first stator (), wherein the rotor () is arranged concentrically relative to the first and second stator () and is arranged between the first and the second stator () in such a way that a first air gap () is formed between the first stator () and the rotor (), and a second air gap () is formed between the second stator () and the rotor (). The invention also relates to an aircraft comprising a rotating electrical machine of this type.

Various embodiments include a drive system for a vehicle, the system comprising: an internal combustion engine for converting chemical energy stored in a liquid fuel into mechanical energy; a fuel tank for storing fuel for use by the internal combustion engine; and an electric machine having a rotor, a stator, and a cooling system for cooling at least one component of the electric machine using a cooling liquid. The cooling liquid comprises the fuel.

The invention relates to an electrical conductor which is made up substantially of one or even several metal conductors which are sheathed by a graphene layer. Particularly in the case of the electrical conductor transporting an alternating current, the current in the conductor is forced radially outwards and therefore flows in the graphene layer. Since graphene has a substantially better conductivity than the materials customary in this application, such as copper for example, relatively low losses are accordingly produced and substantially higher degrees of efficiency can be achieved. The electrical conductor constructed in this way is used in a stator and/or rotor winding of an electrical machine, so that it has a significantly elevated power-to-weight ratio.
