Abstract

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.
