Abstract (en)
[origin: WO2020148057A1] An electric motor (1), at least having: a housing (2) and a stator (3) situated therein with at least a plurality of coils (4); and a rotor (5) with at least one magnet (6), an axis of rotation (7) and an outer circumferential surface (8); wherein: the stator (3) and the rotor (5) are adjacent to one another along the axis of rotation (7); the rotor (5) has a fluid conduction structure (9) between the axis of rotation (7) and the outer circumferential surface (8); the fluid conduction structure (9) has at least one surface (13) extending at least radially (10) and being inclined relative to at least a circumferential direction (11), or to an axial direction (12) running parallel to the axis of rotation (7); and at least part of a fluid flow (14), transported through the fluid conduction structure (9) inside the housing (2) during the operation of the motor (1), can be conducted over the coils (4).
