Abstract

Dispositivo di sensore di velocità di rotazione di un organo rotante (4) montato tramite un cuscinetto volvente su un organo non rotante (3), che comprende un anello multipolare (17) solidale con l'organo rotante, un sensore (19), reso solidale con l'organo non rotante, e un mezzo concentratore di flusso magnetico che è disposto nell'immediata vicinanza dell'anello multipolare e che coopera con il sensore per concentrare e per incanalare il flusso magnetico emesso dall'anello multipolare. Il mezzo concentratore di flusso presenta una forma anulare e comprende almeno una prima fiancata (24), che presenta una parte radiale un cui bordo circolare è circonferenzialmente dotato di un labbro di tenuta (25) destinato a venire in contatto direttamente o indirettamente con l'organo rotante (4), e una seconda fiancata (26) dotata di denti radiali (27) regolarmente distanziati secondo un percorso circolare. L'ANELLO MULTIPOLARE è a magnetizzazione assiale ed è disposto nello spazio assiale compreso tra la parte radiale della prima fiancata da una parte e i denti radiali della seconda fiancata dall'altra parte, di modo che i denti radiali sono tutti situati assialmente di fronte ai poli magnetici con la stessa polarità dell'anello multipolare.fig. 2.
