Portal Scanner introduction
The Portal Scanner is controlled by the MagScope measurement & analysis software, together with several plug-ins.
Read moreThe Magcam Portal Scanner is a motorized mechanical X-Y-Z stage with an integrated magnetic field camera for magnetic field mapping of larger permanent magnets and magnet assemblies.
The Portal Scanner is controlled by the MagScope measurement & analysis software, together with several plug-ins. The scanner uses a Beckhoff PLC controller to control the 3 axis.
The controller can be initialized in two ways:
- Creating a new Scanner Action on a network in MagScope
- Loading a saved network (‘preset’)
To create a new network, select ‘Configure Actions’ from the network context menu.
Saving measurement data
MagScope provides the option to save measurement data manually (one measurement) or automatically (measurements on multiple magnets).
Read moreMagScope provides the option to save measurement data manually (one or a few measurements) or automatically (measurements on multiple magnets).
Manually
To save the measurement data to a data file, right-click one of the elements in the network, e.g. the Camera element and select Save…:
A dialog is shown that asks the user to which type of file (.mcb or .csv) the data should be saved. Select the desired format.
Extracting a 1D cross-section
To gain more insight in the magnetic field of the permanent magnet, it is possible to extract a cross-section from the data in MagScope by using the lines feature in the 2D Plot element.
Read moreTo gain more insight in the magnetic field of the permanent magnet, it is possible to extract a cross-section from the data in MagScope by using the lines feature in the 2D Plot element. Six different lines are available, given the user every option to learn more about the magnetic field details:
- Cross
- Circle
- Diagonal line
- Horizonal line
- Vertical line
- Rectangle
A circular cross-section is used to explain this feature.
In the toolbar on top, click on the Circle.
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 moreTwo 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.

2D Plot
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 basics
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.

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 moreMost 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:
Image stitching
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 moreThe 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 moreThe 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:
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.
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.
Gear tooth speed sensor magnets
The MiniCube1D camera instantly measures the Bz field distribution, which is the most important parameter 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.
Crack Detection
The MagFit module integrated in the MagScope software can filter out the signature of cracks from the background field distribution and automatically detect cracks.
100% in-line production testing
The Magcam systems are very suitable for 100% automated in-line production testing and quality control.
