Abstract

In this work, a new 2-D magnetic measurement method is developed. Also, the rotational loss of non-oriented electrical steel sheets from the viewpoints of the rotational direction and declination angle as well as phase difference between magnetic field H and magnetic flux density B are studied. The magnetic properties of B-H loops and the losses are measured under the alternating and rotating field at 50 Hz. Results show that the loss difference between the clockwise and anticlockwise rotation is greatly influenced by the angles δ_x and δ_y between direction of H_x, H_y and B_x, B_y.
