Measurement and Analysis of Magnets
The Magcam magnetic field cameras and MagScope measurement and analysis software offer a wide variety of features to measure the different magnetic properties allowing a full analysis of permanent magnets. Magcam’s magnetic field cameras measure and capture in detail the magnetic fields by using a unique Hall sensor array technology.
At the heart of the magnetic field camera is a sensor chip containing an integrated two-dimensional array of 16,384 (128 x 128) microscopic Hall magnetic field sensors, with an inter-sensor distance of only 100 micron. Each sensor independently measures the local magnetic field, resulting in a quantitative 3D magnetic field map with high spatial resolution, measured at high speed (< 1 sec). The total measurement area of this sensor array is 12.7x12.7mm. See the Technology section for more details.
To measure larger magnets, magnet assemblies and rotors, Magcam offers several scanning systems. For more details see the Products section.
The MagScope software offers a wide variety of features to show in detail the different magnetic properties and provides a full analysis of permanent magnets, assemblies and rotors.
Quantitative magnetic field maps, measured with the magnetic field camera, contain large amounts of information about the magnet’s quality. The maps are analyzed using the versatile magscope software, resulting in a thorough and fast analysis of the magnet. Many quantitative magnet properties are extracted from the measurement data, making the Magcam system ideal for both R&D and production applications.
For uniaxial magnets, the magnetization vector and its deviation angle are most important, while for multipole magnets the pole uniformity, north-south pole symmetry and deviations in pole segment angles are quality-defining parameters. Also field homogeneity and material defects, as well as magnetization defects are important in many applications.
