CASE STUDY
" We are now designing a high-volume production line for
which we are keen to incorporate your technology " commented
the project manager.
After the on-site installation by Magcam engineers and the
obligatory factory acceptance tests, the customer's engineers
were trained in programming measurement and analysis configurations
(also called 'networks') in the MagScope software.
Operators were trained to handle the measurement process.
Calibration and maintenance procedures were likewise discussed.

analysis of the axial magnetic field component, integrated in the
radial direction.
Magcam proposed to use the first test results as a starting point
for identifying the correlation between good and bad rotors and
as a guideline for the final end-of-line tests. This will eventually
define the relevant quality parameters for a Pass/Fail window.
This process allows the identification of faulty rotors early in
the production process, thereby improving production yield and
reducing scrapped components later in the process.
The Magcam system can also be used in the design and prototyping
phases to identify magnetic issues early on in the development
and speed up time-to-market.
Once the prototype testing process is finished at the UK
subsidiary that was acquired last summer by a German
premium-class car manufacturer, an innovative Magcam endof-line
testing setup will be incorporated into a mass-production
manufacturing line.
History of this Case Study
Initial talks about this prototype line started almost 3 years ago
after an even earlier introduction of the Magcam technology to
the Senior Engineering staff on fairs and during personal meetings.
Initial feasibility tests ran on a Magcam XY Portal Scanner
delivering great results but with insufficient cycle times. Therefore
Magcam developed the Axial Flux Rotor Scanner as an
add-on for its portal and rotor scanner solutions.
In the meantime, Magcam's Axial Flux Rotor Scanner has become
a standard product and has gained ever increasing interest
in the market. For more info see www.magcam.com.
As of January 2023, Hitachi Metals has become Proterial.
Proterial Ltd is a global supplier of castings, cable, steel-related products
and magnetic products including NEOMAX®
Plot of the axial magnetic field component with pole peak and pole
angle analyses.
On the Magcam dedicated Windows computer running the Magcam
MagScope software, data is collected as raw data, which
can be exported to CSV data format. Information transfer to the
customer SQL database is realized by means of Python scripts
and daily reports are generated.
Next, Magcam was working on a new cogging torque analysis
method for these axial flux rotors, similar to the radial flux rotors.
This is already realized and proven by many users to be a very
powerful feature.
A handheld barcode scanner was chosen to realize a semiautomatic
handling process in a prototype line. The operator's
identity, the used tooling, rotor serial number, etc. are processed
and secure the selection of a correct predefined measurement
configuration.
