Abstract

LA INVENCION SE REFIERE A UN ARROLLAMIENTO DEL ROTOR PARA UNA MAQUINA ELECTRICA, EN PARTICULAR DE UN TURBOGENERADOR REFRIGERADO POR AIRE CON UN EJE DE ROTACION (1) Y MULTITUD DE ESPIRAS ELECTRICAMENTE CONDUCTORAS (2) QUE CON RESPECTO AL EJE DE ROTACION (1) VAN APILADAS RADIALMENTE Y FORMAN VARIOS TRAMOS AXIALES (4) Y TRAMOS TANGENCIALES (5). CADA TRAMO AXIAL (4) TIENE UNA FORMA SENSIBLEMENTE RECTA, APROXIMADAMENTE PARALELA AL EJE DE ROTACION (1), Y LLEVA UNOS PRIMEROS CONDUCTOS DE REFRIGERACION (8) QUE CON RESPECTO AL EJE DE ROTACION (1) ESTAN DISPUESTOS EN UN PLANO MERIDIONAL Y ATRAVIESAN TODAS LAS ESPIRAS (2). CADA TRAMO TANGENCIAL (5) VA CURVADO ALREDEDOR DEL EJE DE ROTACION (1), UNIENDO ENTRE SI DOS TRAMOS AXIALES (4) Y DISPONE DE LOS CORRESPONDIENTES SEGUNDOS CANALES DE REFRIGERACION (9), CADA UNO DE LOS CUALES ESTA SITUADO EN EL INTERIOR DE UN ARROLLAMIENTO RESPECTIVO (2). EVENTUALMENTE SE HAN PREVISTO EN LOS TRAMOS AXIALES (4) UNOS TERCEROS CONDUCTOS DE REFRIGERACION (15) DISPUESTOSDE FORMA ONDULANTE EN PLANOS MERIDIANOS.
