Electric machine having a stator with winding rods cooled

摘要

"Electric machine having a stator winding bars of a cold.The invention patent refers to an electric machine comprising a stator (10) with a core laminate (11) in which two or more slits (12) are provided.Running in the axial direction and in which two or more bars winding (13)14) are arranged one above the other in the radial direction and are separated from one another by spacers (19) between them and in which channels (20) which run parallel to the bars of the winding (13)14) are provided, through which a cooling medium flows to cool the winding rods (13, 14).In a machine as presented, cooling considerably better winding is achieved with low complexity in the tubular spacer elements (19).Which extend in the axial direction and whose interior in each case to form a channel (20) for the cooling medium are used as spacers.
