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 optical triangulation Laser Distance Sensor is an add-on to the Magcam Portal Scanner and Rotor Scanner for measuring the dimensions of magnets and magnet assemblies under test.
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 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.
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.
Pass/fail quality control
Using the quantitative results of a MagFit analysis, an additional pass/fail analysis can be easily and directly performed. For this the Python scripting module for MagScope is used.Read more
Using the quantitative results of a MagFit analysis, an additional pass/fail analysis can be easily and directly performed.
In the Python script, the results of a MagFit element in MagScope are accessed using the ‘Results()’ function of the ‘IElement’ class. In the return variable of this function, the results can be obtained and displayed.
Magcam engineers can assist our customers with writing Python scripts when desired.
The 3D plug-in for MagScope adds the functionality for analyzing the full three-component magnetic field distribution recorded with the MiniCube3D magnetic field camera.
Rotor Scanner introduction
The Rotor Scanner is controlled by the MagScope measurement & analysis software, together with several plug-ins.Read more
The Rotor Scanner is controlled by the MagScope measurement & analysis software, together with several plug-ins. The software takes care of automated scanning and image stitching to display the magnetic field distribution of the complete rotor in one image. The analysis of the radial, tangential and axial magnetic field components (with MiniCube3D camera) can be performed in great detail.
It is possible to detect zero crossings automatically, count and measure the poles, check the uniformity and symmetry of north-south poles, perform a Fourier analysis of hamonics, etc.
Saving settings and networks
When a network setup is configured for a specific measurement and /or analysis flow, it can be saved to a specific file, which can be loaded later again.Read more
When a network setup is configured for a specific measurement and /or analysis flow, it can be saved to a file, which can be loaded later again.
To save a network to a file, select Save as… in the network’s context menu:
By default, MagScope will propose to save the file in the ‘C:/ProgramData/Magcam/MagScope/Presets/Custom’ directory. The ‘Presets’ directory is special, since files that are saved in this folder are directly available from the MagScope menu.
Portal Scanner introduction
The Portal Scanner is controlled by the MagScope measurement & analysis software, together with several plug-ins.Read more
The 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 more
MagScope provides the option to save measurement data manually (one or a few measurements) or automatically (measurements on multiple magnets).
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 more
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. Six different lines are available, given the user every option to learn more about the magnetic field details:
- Diagonal line
- Horizonal line
- Vertical line
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 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.
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.
