Measurement of alternating magnetic properties of grain-oriented materials using a round rotational single sheet tester

摘要

This paper presents a measurement of grain-oriented electrical steel under pure alternating magnetic flux condition at inclination angles from -90 degrees to 90 degrees with respect to the rolling direction (RD). The measurement was carried out using a round rotational single sheet tester. The results show a strong asymmetry of alternating power loss and magnetic field strength with respect to the RD. The alternating power loss depends on the side of the band where the specimen was cut off. (c) 2005 Elsevier B.V. All rights reserved.
