Abstract

DOS IMANES RIGIDOS DE SECCION PARCIALMENTE ANULAR (4 Y 5) SE SOSTIENEN DENTRO DE UNA ENVOLTURA DE METAL CILINDRICA (1) A BASE DE MEDIOS SEPARADORES (9 Y 10) QUE COMPRENDEN UNA INSERCION DE METAL LIGERO RIGIDO 89), DISPUESTOS ENTRE LOS DOS BORDES LIBRES (6 Y 7) DE LOS IMANES Y UN SEPARADOR ADICIONAL EN LA FORMA DE UN MUELLE ELASTICO DEFORMABLE CON PERFIL DE U (10), QUE ES DISPUESTO ENTRE LOS OTROS DOS BORDES LIBRES (28 Y 29) DE LOS IMANES. LA INSERCION DE METAL LIGERO (9)TIENE DOS EXTENSIONES LATERALES EN DIRECCIONES OPUESTAS (12) DISPUESTAS EN CONTACTO CON CADA UNO DE LOS IMANES (4 Y 5) Y EL LADO CERRADO (11) DE LA ENVOLTURA 81) PARA COLOCAR LOS IMANES (4 Y 5) LONGITUDINALMENTE CON LA ENVOLTURA (1). LA INSERCION (9) TAMBIEN TIENE MEDIOS DE COLOCACION (16) ADYACENTES AL LADO ABIERTO DE LA ENVOLTURA (1) PARA COLOCAR LA TAPA EXTREMA EN UN ANGULO RELATIVO A LA ENVOLTURA (1) Y ASI PROPORCIONAR UNA COMUNICACION OPTIMA. LOS MEDIOS DE COLOCACION COMPLEMENTARIOS (15) PUEDEN INCLUIR UN MIEMBRO CONDUCTOR ELECTRICO QUE CONTACTA LA INSERCION PARA PROPORCIONAR UNA CONEXION A TIERRA CON LA TAPA FINAL. MAS AUN, LA INSERCION 89) SIRVE COMO DESVIACION MAGNETICA ENTRE LOS IMANES (4 Y 5) DE TAL FORMA QUE, AL MAGNETIZAR LOS IMANES (4 Y 5), EL EJE MAGNETICO YACE EN UN SEGUNDO PLANO (8) PERPENDICULAR DESDE EL EJE LONGITUDINAL (2) HACIA LA INSERCION (9), REDUCIENDO ASI LA VIBRACION RADIAL DEL ROTOR (24) Y EL RUIDO DURANTE LA OPERACION.
