Soft Magnetic Materials Characterization Platform

The Characterization Lab plots the hysteresis cycles and evaluates losses of magnetic materials used in electrical machines. The lab includes a single sheet tester (SST) for unidirectional field measurements, a rotational power loss tester (RPT) for 2D and rotating field tests and an Epstein frame for standard reference tests.
