Operation principle
The rotor tester system determines the symmetry of multipolar
magnetized DC permanent magnet rotors.
The measuring system measures the magnetic field strength over
the surface of a rotating rotor and determines the distribution
of the field, its peak values, zero crossovers and their distance,
as well as the total flux of each pole. Depending on these values
the symmetry of the magnetization can be calculated.
The measuring system consists of the following components: Mechanics
equipped with drive for the admission and turn of the rotors,
measuring sensor system with hall sensors, Gaussmeter for field
strength measurement , software package ROT-EXPERT, PC interface
for the data acquisition and control of the measuring procedure.
