Abstract

ROTOR PARA MAQUINA DINAMOELECTRICA. SE DESCRIBE UN ROTOR (12) PARA MAQUINA DINAMOELECTRICA VENTILADA RADIALMENTE QUE TIENE UNA PLURALIDAD DE RANURAS LONGITUDINALES (20), CONTENIENDO CADA RANURA UN CONDUCTOR DE DEVANADO DE CAMPO (25), UNA BARRA AMORTIGUADORA (41), Y UNOS SEGMENTOS DE CUÑA (42) QUE CIERRAN LA EXTREMIDAD SUPERIOR DE LA RANURA, ESTANDO LOS SEGMENTOS DE CUÑA (42) SUJETOS EN LA BARRA AMORTIGUADORA (41) POR MEDIO DE CHAVETAS DE FIJACION (45). MEDIANTE LA INTRODUCCION DE UNA CHAVETA MACIZA (45) EN UNA RANURA DE CHAVETA ELEGIDA (44) PROXIMA A UN PUNTO SITUADO A MITAD DE CAMINO EN EL SENTIDO DE LA LONGITUD DEL ROTOR, Y MEDIANTE LA INTRODUCCION DE CHAVETAS DIVIDIDAS EN LOS DEMAS PUNTOS, SE LIMITA LA MIGRACION AXIAL ACUMULADA DE LAS CUÑAS RESPECTO A SU RESPECTIVA BARRA AMORTIGUADORA (41) GARANTIZANDO ASI UNA VENTILACION ADECUADA A TRAVES DE LOS CONDUCTOS (38) DISPUESTOS RADIALMENTE.
