Two-dimensional magnetization characteristics
- Oita Univ. (Japan)
Appeals for improved energy efficiency in recent years have been attended by increased emphasis on the magnetic characteristics of the magnetic materials used in transformer cores and other components, as a means of improving the efficiency of electrical equipment. In conventional magnetic measurements, only the same components of the magnetic flux intensity B and the magnetic field intensity H in the excited direction are measured. In short, the measured values are treated as scalar quantities. Since it is well known that B and H have a phase difference in space, these quantities should be dealt with as vectors. The authors have used a two-dimensional magnetic measurement apparatus to obtain a precise understanding of the behavior of B and H in magnetization processes. In conventional measurements, when the excited direction does not correspond to the rolling direction, the locus of the vectors of B is not an alternating flux; that is, it becomes a loop. Therefore, the iron loss obtained by the conventional method is different from that for two-dimensional measurements.
