Title (EN) SQUIRREL CAGE ROTOR WITH COPPER FILLED PLASTIC BARS AND RINGS
(FR) ROTOR À CAGE D'ÉCUREUIL COMPRENANT DES BARRES ET DES ANNEAUX EN PLASTIQUE REMPLIS DE CUIVRE
Abstract:
(EN) A rotating element for a dynamo-electric machine such as an electric induction motor. The rotating element includes a plurality of axially stacked laminations cooperatively defining a plurality of arcuately spaced bar slots. The rotating element also includes a plurality of bars, with each bar extending through one of the bar slots. Each of the bars comprises copper-impregnated polymer.
(FR) La présente invention concerne un élément rotatif pour une machine dynamo-électrique telle qu'un moteur électrique à induction. L'élément rotatif comprend une pluralité de stratifications empilées axialement qui définissent en coopération une pluralité de fentes à barres espacées de façon arquée. L'élément rotatif comprend également une pluralité de barres, chaque barre s'étendant à travers l'une des fentes à barres. Chacune des barres comprend du polymère imprégné de cuivre.
