Abstract
Various implementations include a stator assembly for an axial flux permanent magnet machine. The stator assembly may include a set of stator bars and a set of shoes for the stator bars. A shoe may be provided at one or each end of a stator bar. The stator assembly may further include a set of coils each wound around a respective stator bar. Each shoe has an inner surface adjacent to the end of one of the stator bars. The end of each stator bar has a rim, and each inner surface has a cut-away region over part of the rim to reduce a component of magnetic flux at the end of the stator bar.
