Abstract
An electric motor attached at one axial end to a frame for a dishwashing machine or the like and which at its opposite free end is provided with a cooling blower for generating air jets. The improvement comprises cooling channels for the air arranged around the stator, the cooling channels having outlet openings for the cooling air facing the frame and situated at a predetermined distance from the frame with the exception of one or some of the channels at one side of the motor which in combination with the frame are closed in an axial direction and are provided with outlet openings for the cooling air so that the cooling air is directed inwardly against the shaft at the end of the motor turned towards the frame.
