Abstract
Rotational magnetic flux in the plane of steel laminations causes core losses which far exceed than alternating magnetic flux. Traditional testing methods such as Epstein frame detected only in one direction may lead to inaccurate predictions of core losses. This paper developed a 3-D magnetic properties testing device to measure the magnetic properties of high grain-oriented silicon steel. By using the automatic control system and novel surface B-H sensing coils, the dynamic magnetic hysteresis properties of the silicon steel are accurately measured with a static magnetic field along the laminated direction of the specimen. Finally, an ellipsoid magnetic anisotropy model is established which parameters can be identified by the magnetic measurement results with biased magnetic field.
