Furthermore, different- and thus relieved the pole piece, Borrowed expansions of pole shoe and pole core strong 50 successive asynchronous starts of the Ma-curvatures of the poles occur, which are to multiply at shorter intervals than before without th stresses on the pole claws and others are possible.

Alle diese Erscheinungen sind eine gert und eine große Betriebssicherheit erreicht, was Folge der zu langsamen Abfuhr der Polschuhwärme. 55 insbesondere bei hoch ausgenützten Maschinen gro-Aufgabe der Erfindung ist, eine Anordnung zur ßer Eisenlänge, beispielsweise bei Motor-Generatoren Flüssigkeitskühlung der ausgeprägten Pole eines für Pumpspeicherwerke, von wesentlicher Bedeutung Schenkelpolläufers zu schaffen, die auf einfacher ist.could know. All of these phenomena are a device and achieve a high level of operational reliability Consequence of the too slow dissipation of the pole shoe heat. 55 is a major task, especially in the case of highly utilized machines of the invention is an arrangement for ßer iron length, for example in motor-generators Liquid cooling of the salient poles of one for pumped storage plants, essential To create thigh pole walker that is easier on.
