Abstract

We report on further advancements in the field of magnetic field camera technology for magnet inspection, based on high resolution high speed two-dimensional magnetic field mapping of the magnetic field distribution of permanent magnets. The advancements presented here extend the applications of the technology to inspection of large magnets and magnets with non-planar geometries, such as rotary symmetric magnets (e.g. permanent magnet rotors or radially or diametrically magnetized cylinder or ring magnets for sensor applications.
The innovation consists of combining multiple redesigned magnetic field camera sensor modules into a single large area magnetic field camera, that can record the magnetic field distribution in a virtually unlimited area, at about the same speed as one single sensor module, due to parallel read-out. The technology is suitable for both manual and automated magnet inspection tasks, as well as development and quality control applications.
