Bladed Balancing Disc for Stator End Winding Cooling

The patent combines the balancing disc function with the cooling function by integrating coolant flow passages directly into the balancing disc structure. The balancing disc now serves dual purposes: maintaining rotor lamination stability and providing thermal management for stator end windings through internal coolant channels that draw heat away from the windings.

The balancing disc acts as an intermediary component between the rotor shaft and the stator end windings. By positioning the balancing disc radially outward from the rotor and incorporating coolant passages, it mediates heat transfer from the stator end windings to the coolant flowing through the disc, thereby protecting the windings from overheating while maintaining structural stability.

The patent merges the cooling system with the existing balancing disc component, eliminating the need for separate cooling mechanisms. The coolant passages are integrated directly into the balancing disc structure, allowing the same component to perform both structural support and thermal management functions, thereby reducing overall system complexity despite adding cooling capability.

The balancing disc is transformed into a multi-functional component that simultaneously provides mechanical support for rotor laminations and thermal management for stator end windings. By incorporating coolant flow passages into the balancing disc, the component achieves universality, performing both structural and thermal functions within a single element, thus avoiding the need for additional separate cooling devices.
