Abstract (en)

[origin: WO2018166977A1] The present invention relates to an electrical machine comprising at least one disc-shaped stator (1) with at least one winding (7) of electrically conductive wire, and at least one rotor (2) that is rotatable relative to the stator (1) and that has a first permanent magnet (31) and at least one second permanent magnet (32), the magnets being arranged such that a north pole (N) of the first permanent magnet (31) and a south pole (S) of the second permanent magnet (32) point towards the stator (1). The winding (7) is arranged on the disc-shaped stator (1) radially around the circumference in a serpentine configuration having alternating radially arranged portions (8) and tangentially arranged portions (9), such that loops (10) of the winding (7) arranged on two opposing surfaces of the disc-shaped stator (1) only partly overlap one another in their radially arranged portions (8), or only partly overlap one another in their tangentially arranged portions (9), and the winding (7) is arranged alternately on one of the two surfaces (33,34) of the disc-shaped stator (1), or one winding (7) of the wire is arranged on each of the surfaces (33,34) of the disc-shaped stator (1).
