Abstract

CON UNA INSTALACION DE ABASTECIMIENTO INDUCTIVO DE ENERGIA DE UNA CONEXION ELECTRICA DISPUESTA ENCIMA DE UN EJE (10) ROTATORIO, ESPECIALMENTE DE UN EMISOR Y UN PUNTO DE MEDICION CORRESPONDIENTE CON UNA BOBINA PRIMARIA (20) DISPUESTO ESTACIONARIO CERCA DEL EJE (10) Y UNA BOBINA SECUNDARIA (38) ROTATORIA CON EL EJE (10) ESTA PREVISTA PARA LA BOBINA PRIMARIA (20) UN NUCLEO DE BOBINA (32) FERROMAGNETICA DE FORMA - U, DEL CUAL LAS PIERNAS (28, 30) ESTAN DISPUESTAS UNA ATRAS DE OTRA EN DIRECCION AXIAL DEL EJE (10) Y ALINEADAS CON SUS FINALES LIBRES (34, 36) AL EJE (10). ADEMAS LA BOBINA PRIMARIA (20) CONSTA DE DOS PARTES (16, 18) DISPUESTOS ENCIMA DE LAS DOS PIERNAS (28, 30). ENCIMA DE ESO LA BOBINA SECUNDARIA (38) ESTA DISPUESTA APROXIMADAMENTE EN EL CENTRO ENTRE LAS DOS PIERNAS (28, 30) DEL NUCLEO DE BOBINA (32) ENCIMA DEL EJE (10).WITH AN ENERGY INDUCTIVE SUPPLY FACILITY OF AN ELECTRICAL CONNECTION ARRANGED ABOVE A ROTARY AXIS (10), ESPECIALLY OF A TRANSMITTER AND A MEASURING POINT CORRESPONDING WITH A PRIMARY COIL (20) STATIONARY DISPOSAL NEAR THE AXIS (10) SECONDARY (38) ROTARY WITH THE SHAFT (10) IS INTENDED FOR THE PRIMARY COIL (20) A NUCLEUS OF COIL (32) FERROMAGNETICA OF U-FORM, OF WHICH THE LEGS (28, 30) ARE ARRANGED ONE AGAIN IN ANOTHER DIRECTION AXIAL FROM THE AXIS (10) AND ALIGNED WITH THEIR FREE END (34, 36) TO THE AXIS (10). ALSO THE PRIMARY COIL (20) CONSISTS OF TWO PARTS (16, 18) ARRANGED ABOVE THE TWO LEGS (28, 30). ABOVE THAT THE SECONDARY COIL (38) IS DISPOSED APPROXIMATELY IN THE CENTER BETWEEN THE TWO LEGS (28, 30) OF THE COIL NUCLEUS (32) ABOVE THE AXLE (10).
