Abstract: front page image
(EN)An angle position sensor comprises a rotor core (1) and a stator core (2) which is coaxially arranged around the rotor core (1), wherein a first gas gap (3) is arranged between the rotor core (1) and the stator core (2); the interior of the rotor core (1) is provided with a second gas gap (10), and a hard magnetic body (12) is arranged in the second gas gap (10); the stator core (2) is provided with a third gas gap (20), and a flux sensing element is arranged in the third gas gap (20). The combination of the hard magnetic body and the rotor core is used to substitute the design proposal of the ring-shaped magnet in the prior art, so that a favorable linearity is obtained in a wider range.
(FR)Un capteur de position angulaire comprend une carcasse de rotor (1) et une carcasse de stator (2) qui est agencée de manière coaxiale autour de la carcasse de rotor (1), un premier vide de gaz (3) étant agencé entre la carcasse de rotor (1) et la carcasse de stator (2); l'intérieur de la carcasse de rotor (1) est pourvue d'un deuxième vide de gaz (10), et un corps magnétique dur (12) est agencé dans le deuxième vide de gaz (10); la carcasse de stator (2) est pourvue d'un troisième vide de gaz (20), et un élément de détection de flux est agencé dans le troisième vide de gaz (20). La combinaison du corps magnétique dur et de la carcasse de rotor est utilisée pour substituer la proposition de conception de l'élément en forme d'anneau de la technique antérieure, de sorte qu'une linéarité favorable est obtenue dans une plus grande plage.
