Abstract
An air-cooled electromotor has a stator including a plurality of laminations 1 of non-circular external contour. The laminations are mutually offset in the direction of rotation of the rotor of the electromotor so that corners 2 or projections of the laminations are exposed to cooling air and act as cooling fins for the stator. <IMAGE>
