摘要： A method for producing a winding head support for a rotor of a rotating electric machine. To enable the production of even particularly large winding head supports in a simultaneously simple manner, it is provided that the winding head support is formed using an additive manufacturing process, in particular by wire arc buildup welding. Embodiments also relate to a winding head support.

摘要： The invention relates to a liquid cooling method for a hydroelectric generator which cools the winding of the rotor via a primary cooling liquid circuit, said cooling liquid being maintained in the circuit by the produced centrifugal force. The dissipation of the thermal energy takes place via a secondary cooling liquid which flows once vertically through the system. According to the invention, said thermal exchange takes place via a co-rotating heat exchanger in the center of the rotor. The invention also relates to a device for carrying out such a method.
