摘要： Driven by an industrial need for advanced inspection equipment for permanent magnets in many different applications, among which the high-quality magnets used in sensor applications, we have presented the capabilties of the magnetic field camera (MagCam) measurement and analysis system, a powerful and unique measurement platform for fast and accurate live inspection of both uniaxial and multipole permanent magnets. Measurements and analyses on different kinds of magnets were performed, showing the capabilities of the system to perform a full characterization of small permanent magnets, including the quality-defining characteristics such as angle failure, pole symmetry and homogeneity for multipole magnets and magnetization vector size and angle deviation for uniaxial magnets. Using advanced data analysis and combining theoretical magnet modeling and MagCam measurements, a lot of extra information can be extracted from the measurement data, including the magnet's exact position and orientation, the magnetization vector, a theoretical best fit to the MagCam map and a residual MagCam map showing all 'imperfections' in the magnet. This powerful magnet inspection platform is well suited for both R&D and industrial (automated) magnet inspection, since it is completely digital, gives fast measurement and analysis results (in seconds), and can be integrated in production lines. These unique characteristics make that the MagCam system is quickly becoming the new industry standard for magnet inspection in virtually all industries where high quality permanent magnets are used.
