Determination of multipolar magnetized permanent magnet rotors Testing of field strength distribution Variable adjustment for rotors with different overall size Variable number of hall sensors Customized design Software with numerous statistical funktions Display of field distribution, peak value, zero crossover, total flux for each pole Integration of mesured data into QM systems 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. Technical data: Rotor Tester Rotor holder: Mechanics with drive for the admission and turn of the rotors Sensor holder: Hall probes with mit variable restraint system for different rotor size Field strength measurement: Gaussmeter with measuring range 1 - 1000 mT, 3 inputs, analogue output ± 10 V PC-Interface: PCI card, 12 Bit D/A, 4 analogue inputs, 2 analogue outputs, 16 digital I/O Software: ROT-EXPERT for Windows Power supply: 230 V, 50 - 60 Hz
