Abstract

Un método para soldar los anillos extremos a las barras de un rotor para el ensamble del rotor de jaula de ardilla incluye ensamblar el rotor en un aparato para soldar con una calza para soldar entre las barras del rotor y los anillos extremos; precalentar el rotor y el aparato para soldar a una temperatura menor que la temperatura de envejecimiento de las barras del rotor y de los anillos extremos y la cual sea suficientemente alta para que la diferencia entre la expansión térmica de las barras del rotor y del aparato para soldar aplique una cantidad predeterminada de presión en la junta de soldar de manera que después de que la junta se suelde y se enfríe, un metal de aporte para soldar que tenga un espesor predeterminado en centímetros pegará las caras extremas de la barra del rotor al anillo extremo, y soldar cada junta para pegar las caras extremas de la barra del rotor con el anillo extremo. Un aparato para soldar para mantener una presión predeterminada en un ensamble de rotor de jaula de ardilla durante el proceso de soldar las barras del rotor a los anillos extremos para formar una junta soldada, donde el ensamble del rotor incluye las barras del rotor dispuestas en un núcleo de rotor y que tienen sus extremos colocados sobre calzas para soldar sobre los anillos extremos, incluye elementos de colocación para colocar el ensamble del rotor en el aparato; elementos de presión para aplicar una cantidad predeterminada de presión sobre los anillo extremos, las barras del rotor y las calzas para soldar del ensamble del rotor de manera que cuando los extremos de las barras del rotor, las calzas para soldar y los anillos extremos se suelden para formar una junta, la junta soldada resultante tenga un espesor predeterminado.
