  • Device for increasing the magnetic flux density in the vicinity of a hall sensor cooperating with a magnet wheel
    Patent number: 6016055
    Abstract: A device for measuring the rotation speed or detecting the direction of rotation of a rotary magnetic field includes a Hall sensor which is mounted as an SMD component on a printed circuit board. A magnet wheel is secured to a rotor spindle of an electric motor and a rotary magnetic field is generated upon its rotation. A magnetic flux guide element is provided for concentrating the rotary magnetic field in the region of the Hall sensor, thereby increasing the sensitivity of the Hall sensor.
