As a further development of Magcam’s magnetic field camera scanners, we report on a combined stand-alone scanner for very fast measurements of the magnetic field distribution of both flat magnets or magnet assemblies on one hand and permanent magnet rotors on the other hand. The new ‘Combi’ scanner is an integration of Magcam’s existing Portal and Rotor scanners into a high precision, PLC controlled 4-axis scanner. The Combi scanner is the result of a complete redesign and has several new features, such as an integrated laser distance sensor for accurate dimensional measurements of samples and a design safety housing. The integrated laser distance sensor allows to accurately measure the height, lateral dimensions and full surface map of magnets and magnet assemblies under test. These dimensional measurements complement the high accuracy magnetic field maps measured by the standard integrated 3D magnetic field camera, used for very fast and accurate magnetic field mapping of permanent magnets, magnet assemblies and PM rotors. Both maps can be overlaid, resulting in a correlation between geometric and magnetic data. The design safety housing protects the operator from any risks related to the mechanical movement of the motorized high-precision slides and protects the scanner and sensors from outside influences. The safety housing comes standard with a sliding door but can optionally be fitted with a safety light curtain for effortless operation. The scanner is controlled by Magcam’s powerful MagScope software, which automatically steers the motorized slides, performs the measurements and analyses the resulting data using powerful algorithms. The new Combi Scanner is an all-round magnetic and dimensional measurement and analysis solution for inspection of permanent magnets, magnet assemblies and PM rotors for use in R&D labs, QC divisions and production lines and for various applications, such as automotive sensor systems, electric motors, medical devices, consumer electronics and magnet production.
