Magcam MiniTable Working Platform
The MiniTable is a working platform for measuring small magnets, to be combined with the MiniCube1D or MiniCube3D magnetic field camera.
The Minicube3D is a 3D magnetic field camera, providing quantitative (Bx,By,Bz) magnetic field mapping in a 12.7mm x 12.7mm 2D plane with a 0.1mm spatial resolution, measured at high speed.
MagScope is Magcam’s advanced data analysis software for measuring and analyzing magnetic field distributions in real time. MagScope is integrated in all our magnetic field cameras and scanners.
The Minicube1D is a compact Bz magnetic field camera containing a patented sensor chip with an integrated two-dimensional array of 16384 microscopic Hall magnetic field sensors.
Magcam Portal/Combi Scanner
The Magcam Portal Scanner is a high-speed 3-axis motorized mapper with an integrated MiniCube1D or MiniCube3D magnetic field camera for measuring large magnets and magnet assemblies.
The optical triangulation Laser Distance Sensor is an add-on to the Magcam Portal Scanner and Rotor Inspector for measuring the dimensions of magnets and magnet assemblies under test.
Magcam Rotor Scanner
The Magcam Rotor Scanner is a 3-axis motorized scan stage with an integrated MiniCube1D or MiniCube3D magnetic field camera for measuring the magnetic field distribution of permanent magnet rotors.
Opening a data file
MagScope supports two types of data files, CSV files and MCB files (the native MagScope format). To open a previously recorded/saved file, one can select File/Open MCB or File/Open CSV, depending on what type of file you want to open.Read more
Two types of data files are supported by MagScope:
- MCB files: the native MagScope format. These are binary files containing magnetic field images. These files can be opened only by MagScope. Their file size is smaller than that of a corresponding CSV file.
- CSV files: ‘Comma Separated Values’ files containing magnetic field distribution data. These files can be opened with other programs, such as Matlab, Excel, Notepad etc.
Note: MagScope is backward compatible with the older ‘.magcam’ file format, as used by earlier versions of MagScope (v.3.x). They can be opened the same way as CSV files.
Creating plots and graphs
MagScope has the ability to show the magnetic field in different plot and graph formats, such as 2D, surface and quiver plots.Read more
MagScope has the ability to show the magnetic field in different plot and graph formats, such as 2D, 1D, surface and quiver plots.
The 2DPlot element visualizes the data in a two dimensional color graph. When creating a 2DPlot element the ‘2DPlot’ window is shown. The 2DPlot allows you to draw following plot elements such as lines and circles. Measurements can be made between plot elements of the same type.
From the plot window, cross-sections and 2D areas can be selected and further analyzed in a new network.
MagScope is built around ‘data’ and ‘networks’. Data is a matrix of measurement points, such as the magnetic field distributions that come from the magnetic field camera. The data is processed inside one or more ‘networks’, where it can be displayed, analyzed, transformed etc.Read more

A network is a chain of ‘Elements’ through which the data flows. There are many types of elements and they can be combined in many ways, making the software very modular and flexible. Each element does something with the data (e.g. a ‘Plot’ element visualizes it) and then the data continues through the network to the next element.
3D analysis elements
In MagScope, most of the analysis elements have additional functionality for analyzing 3-component data. It not only contains the measured Bx, By and Bz components, but also derived components in the used coordinate system.Read more
Most of the analysis elements have additional functionality for analyzing 3-component data. Generally, the component to be analyzed can be selected in a dropdown menu at the top left of the element window. This window not only contains the measured Bx, By and Bz components, but also derived components in the used coordinate system.
For the Cartesian coordinate system the available components are:
The stitcher function in MagScope combines multiple frames or channels into a single image. This way it is possible to stitch multiple measurements from a single camera or measurements from multiple cameras in a single image.Read more
The stitcher function in MagScope combines multiple frames or channels into a single image. This way it is possible to stitch multiple measurements from a single camera or measurements from multiple cameras in a single image. During creation you first need to configure the total image dimensions in the ‘Data Stitcher’ dialog. Here you configure the number of images to combine and the dimensions of the combined image.
Next you will need to configure the location of each image in the total stitched image in the ‘Stitcher’ window.
Python scripting introduction
Magscope supports the use of Python scripts to add unlimited flexibility and functionality.Read more
The Python scripting module for MagScope allows using the analysis results and other data of MagScope in an unlimited number of ways, chosen by the user, who can have his own Python scripts run automatically in MagScope.
The MagScope measurement and analysis software supports the use of Python scripts to add flexibility and functionality. MagScope comes standard with Python script templates which can serve as a basis for writing your own script to define a custom functionality. Alternatively, Magcam offers services for writing custom scripts.
Typical applications include:
2-Pole Rotary Encoder Magnets
For this application the in-plane Bxy field component is important and can be measured with the Magcam MiniCube3D camera.
Multipole Rotary Encoder Magnets
It is important in this application to measure and analyze if the zero crossings and pole peaks are equal.
Linear encoder strip magnets
The detection of the pole peaks and zero crossings as well as the Fourier harmonics analysis is important in this application.
Dipole position sensor magnets
With the MagFit SW module, the magnetization vector magnitude and angle deviation can be accurately measured and analysed.
100% in-line production testing
The Magcam systems are very suitable for 100% automated in-line production testing and quality control.
Permanent Magnet Rotors
Both small electric rotors and larger rotors for e.g. electric vehicle (EV) drives are measured with Magcam’s Rotor or Combi Scanner.
The MagFit module integrated in the MagScope software can filter out the signature of cracks from the background field distribution and automatically detect cracks.
