摘要： A non-contacting position sensor having radial bipolar tapered magnets. The sensor has a semicircular first plate and a second plate. Four semicircular magnets are affixed to the first plate and second plate. Each magnet has a thick end and a thin end. Two magnets generate a linearly varying magnetic field having a first polarity, while the other two magnets generate a linearly varying magnetic field having a second polarity. An air gap is formed in the space between the four magnets. A magnetic flux sensor is positioned within the air gap. The object whose position is to be monitored is rigidly attached to the magnet assembly, causing the magnetic flux sensor to move relative to the magnets within the air gap as the component moves. A varying magnetic field is detected by the magnetic flux sensor, resulting in an electrical signal from the magnetic flux sensor that varies according to its position relative to the four magnets.

摘要： A non-contacting linear position sensor having bipolar tapered magnets. A pair of magnets are positioned adjacent each other and attached to a movable object. Each magnet has a central portion that is thinner than both ends of the magnets. A pair of pole pieces has ends that are arranged spaced apart in parallel relationship about the central portion. The other ends of the pole pieces are located spaced apart with a magnetic flux sensor located between. The magnetic flux sensor senses a variable magnetic field representative of the position of the attached movable object as the magnets move. The magnets have opposite polarities on either sides of the central portion.

摘要： In accordance with the present invention, a non-contacting position sensor using bipolar tapered magnets is provided. A non-contacting position sensor in accordance with the preferred embodiment uses a pole piece having a first plate and a second plate. Four magnets are affixed to the first plate and second plate. Each magnet has a thick end and a thin end. Two magnets generate a linearly varying magnetic field having a first polarity, while the other two magnets generate a linearly varying magnetic filed having a second polarity. An air gap is formed in the space between the four magnets. A magnetic flux sensor is positioned within the air gap. The component whose position is to be monitored is rigidly attached to either the pole piece or the magnetic flux sensor, causing the magnetic flux sensor to move relative to the magnets within the air gap as the component moves. A varying magnetic field is detected by the magnetic flux sensor, resulting in a signal from the magnetic flux sensor that varies according to its position relative to the four magnets. The signal from the magnetic flux sensor is used to provide an indication of the position of the component to be monitored.

摘要： A magnet molding tool for controlling the orientation of magnetic particles in a polymer bonded magnet during injection molding. The tool has magnet mold having a mold cavity. A flux generator is connected to the magnet mold. The flux generator applies a magnetic field in the cavity. A non-magnetic cap is attached to the magnet mold and is dimensioned to modify the magnetic field in the cavity such that the orientation of the magnetic particles in the cavity varies proportionally to the dimensions of the non-magnetic cap. In an alternative embodiment, a slot is formed in the magnet mold and dimensioned to modify the magnetic field in the cavity.

摘要： An extremely reliable and effective position sensor is provided at low cost for determining the relative position of a mechanical linkage with respect to a reference point. The position sensor includes a rotor or bracket which is mechanically coupled to the linkage and contains at least two magnets on opposite walls adjacent a channel opening. The opposing magnets are formed with first and second sloped or ramped sections which produce produce variable magnetic fields as determined by the geometric profile of the magnets. One or more detectors are positioned in the air gap between the opposing magnets. As the linkage is moved, the rotor or bracket moves with respect to the detector causing a change in the strength of the magnetic field detected by the detector whereby the detector determines the position of the movable linkage.
