Abstract
A rotation angle sensor for use in a throttle adjustment device is disclosed, which includes a stator unit having at least two stator part elements positioned relative to each other leaving a spacer recess therebetween; a Hall sensor positioned in the spacer recess; a rotor unit having a magnetic element having a connector element molded into the rotor unit; a plug unit; and a housing unit adapted to partially house the stator unit.
Claims42
A rotation angle sensor for use in a throttle adjustment device, said angle sensor comprising:
- a stator unit having at least two sickle-shaped stator part elements positioned relative to each other leaving a spacer recess therebetween;
- at least one Hall sensor positioned in the spacer recess;
- a rotor unit having a moving element on one side thereof engaged for rotation with the throttle adjustment device and having at least one sickle-shaped magnetic part element attached to said rotor unit at least partially by molding, said rotor unit being moveable relative to said stator unit with said magnetic part element movable within said spacer recess;
- and
- a housing unit adapted to at least partially house the stator unit, the Hall sensor and the rotor unit.
A rotation angle sensor for use in a throttle adjustment device, said angle sensor comprising:
- a stator unit having at least two sickle-shaped stator part elements, said at least two stator part elements being positioned relative to each other leaving a spacer recess therebetween, each of said at least two stator part elements having a connector element;
- at least one Hall sensor positioned in the spacer recess;
- a rotor unit having at least one sickle-shaped magnetic part element, said rotor unit with said magnetic part element being movable relative to stator unit;
- a plug unit electrically connected to said at least one Hall sensor by a stamped lead assembly;
- and
- a housing unit adapted at least partially house the stator unit, wherein at least said connector elements of said stator part elements and the stamped lead assembly are at least partially molded into the housing element.
A rotation angle sensor for use in a throttle adjustment device, said angle sensor comprising:
- a stator unit having at least two stator part elements, said at least two stator part elements being positioned relative to each other leaving a spacer recess therebetween;
- at least one Hall sensor positioned in the spacer recess;
- a rotor unit having at least one sickle-shaped magnetic part element, said rotor unit being movable relative to said stator unit, said at least one magnetic part element comprising two parallel flux conductor sheets, and at least one magnetic segment element in between the flux conductor sheets;
- and
- a housing unit adapted to at least partially house the stator unit, the Hall sensor and the rotor unit.
In a rotation angle sensor comprising a stator unit comprising two asymmetric partial stator elements positioned relative to each other to leave two spacer openings therebetween, at least one Hall sensor located in at least one spacer opening, and a rotor unit comprising a magnet element supported by a magnet support element, and which is movable relative to the stator elements while maintaining an air gap, the improvement, wherein the partial stator elements are divided in the shape of partial rings, comprising a large partial stator element and a small partial stator element, in a ratio of about 2/3 to 1/3, with the two co-linear spacer openings therebetween.
