<p>The winding has conductor bars (5) arranged one above another and comprising cooling slots (11) that are sectionally formed in a deep direction in an extended or tapered manner, where the deep direction corresponds to a radial direction (6) and runs from a rotor surface to a rotation axis. The cooling slots are limited by a limitation wall that runs in a convex type in the deep direction. A transition area is formed between the cooling slots, which are formed in an elongated or linear manner using a miller. A stage is formed in the transition area for turbulence of cooling medium e.g. air. An independent claim is also included for a method for manufacturing a cooling slot in conductor bars of an electrical motor.</p> |
