Abstract
Sheet metal assembly forming a motor rotor and/or stator comprising at least two metal sheets, each metal sheet comprising at least one through hole in a stacking direction, each metal sheet being stacked with the other metal sheets in the stacking direction, each through hole of each metal sheet facing at least partially a through hole of the other metal sheets so as to form one or more air ducts extending in the stacking direction. The metal sheets are configured and arranged so that each air duct comprises at least one shoulder along the stacking direction.
