Abstract
LA INVENCION SE REFIERE A UN SENSOR DE POSICION MAGNETICO, DONDE AL MENOS DOS ELEMENTOS DE ESTATOR ESTAN DISPUESTOS EN UN CAMPO MAGNETICO, Y UNA SONDA DE CAMPO MAGNETICO ESTA LOCALIZADA EN EL ESPACIO DE AIRE ENTRE LOS ELEMENTOS DE ESTATOR. SE DISPONE DE MEDIOS PARA SEGUIMIENTO DE DESPLAZAMIENTO DE UN OBJETO EN UN PLANO PARALELO AL PLANO EN EL QUE SE EXTIENDEN LOS ELEMENTOS DE ESTATOR. EN UN SENSOR DE POSICION INDEPENDIENTE DE UN CONJUNTO AXIAL, LOS MEDIOS CONECTADOS AL OBJETO DE MOVIMIENTO ESTAN DISEÑADOS EN DOS PARTES. CADA PARTE MAGNETICA BLANDA (4A,4B) TIENE AL MENOS UN SEGMENTO Y LOS ELEMENTOS MAGNETICOS BLANDOS ESTAN FIJADOS UNO CON OTRO EN UNA POSICION DE DECALAJE DE UNO CON RESPECTO A OTRO, DE TAL FORMA QUE EL SEGMENTO DEL PRIMER ELEMENTO (4A) ESTA ENFRENTADO AL ESPACIO ENTRE SEGMENTOS DEL SEGUNDO ELEMENTO (4B). LOS ELEMENTOS (2A,2B) DE ESTATOR ESTAN DISPUESTOS ENTRE LOS ELEMENTOS (4A,4B) MAGNETICOS BLANDOS. UN IMAN (3) PRODUCIENDO EL CAMPO MAGNETICO PERPENDICULAR AL PLANO EN EL CUALSE EXTIENDEN LOS ELEMENTOS DE ESTATOR (2A,2B) ESTA COLOCADO TAMBIEN ENTRE LOS ELEMENTOS DE ESTATOR (2A,2B), QUE SE DISPONEN ENTRE LOS ELEMENTOS MAGNETICOS BLANDOS (4A,4B).
