MAGNECODE: Laser Beam Encoding of Permanent Magnets for Automotive Position and Speed Sensors 940633
MAGNECODE uses laser surface heating to pattern permanent magnets for position sensor applications. Thermal and magnetic models provide good predictions of the geometry of the laser heated regions and the resulting spatial variations in the magnetic field. Important design factors are discussed and a comparison with other magnetic sensor technologies is given.
