MAGNETIZATION PROCESSES DATA ACQUISITION SYSTEM

Ovidiu Caltun – Petru Andrei – Alexandru Stancu

   A magnetization process data acquisition system is presented. The acquisition system is based on measuring the magnetization current in the primary coil of an inductor containing the magnetic material and the voltage induced in a secondary coil. The magnetization curves are computed by numerical integration in HysterSoft. Our system allows the measurement of minor and major hysteresis loops, power loss, complex magnetization processes such as first-order reversal-curves, and the computation of Everett functions and susceptibility and Preisach diagrams.
