A stator assembly includes a stator core defined by an inner periphery and an outer periphery, and a plurality of coils. The stator core includes a stator yoke. Each coil of the plurality of coils includes a first set of segments and a second set of segments each extending between the inner periphery and the outer periphery of the stator core. The first set of segments is arranged to form a first coil portion having a “V” shape and the second set of segments is arranged to form a second coil portion having a “V” shape. The first coil portion and the second coil portion each have a vertex and two ends. The ends of the first coil portion are coupled to the ends of the second coil portion. Other example stators, and example dynamoelectric machines and compressors including one or more stators are also disclosed.

An axial flux machine has an annular stator and two rotor elements mounted rotatably relative to the stator about an axis of rotation. A first rotor element is arranged axially adjacent to a first end face of the stator and a second rotor element is arranged axially adjacent to a second end face of the stator. The stator has a plurality of stator cores, distributed in a circumferential direction of a circular line extending about the axis of rotation, wherein at least one stator core has a plurality of radially extending guide segments that are stacked on top of one another in the circumferential direction and are of plate-like design. At least a partial quantity of the guide segments have, on the radial outer side thereof and/or the radial inner side thereof, a retaining accommodated in an interlocking manner on at least one supporting region fixed to the housing.
