MAGNETOSCAN | MAGNETIC MEASURING SCANNER
A magnetic measuring scanner, the Magnetoscan is designed to measure the superficial magnetic
induction of permanent magnet devices that exhibit axial or radial multipolar magnetization, as is
the case with rotors or stators.
The Magnetoscan works by rotating and recording the magnetic field versus the angular
displacement at a particular level and distance. The measurement is taken by a Hall probe,
which is connected to a gaussmeter. The Hall probe is positioned with micrometrical accuracy
at every distance from the surface of the sample by a precise mechanical tool with 3 axes. The
sample is fixed to the rotating base through a shaft holder chuck; an interchangeable holder
allows measurement of the samples with a shaft dimension between 0.5 to 15 mm.
Once the rotor is set on the support and the probe is positioned to the desired distance and
height, the measurement is carried out in a fully automated mode. The sample performs a
complete revolution (plus approximately 10°) in about 30 seconds, during which the induction
is measured and sent to the connected PC, which processes and displays the measured values.
The measurement is fully automated and controlled by a dedicated software program that
records 10,000 measurements per revolution, with a resolution accuracy of 0.036°. The software
provides many forms of scanned data, including: visualization of diagram angle-induction, peak
detection, angular shift, harmonic distortion, and FFT.
