Abstract

The invention relates to an electric machine of the axial flux type, comprising a circumferential stator structure (100), a rotor structure (200) intended for magnetic interaction with the stator structure. The stator structure (100) is double- sided comprising a first stator core (101), a second stator core (102) and a winding (40, 41 to 43, 45, 50, 51 to 53) in the stator cores. The winding (40, 41 to 43, 45, 50, 51 to 53) of the stator structure is such that the winding comprises a crossover point (42) on the side of the perimeter of the stator structure, wherein the winding proceeds, i.e. continues, from the first stator core (101) to the second stator core (102), and that the winding comprises a return crossover point (52) on the side of the perimeter of the stator structure, at a point different from the crossover point, wherein the winding returns, i.e. continues, from the second stator core (102) to the first stator core (101).
