Rotational power loss was measured on non-oriented and grain-oriented silicon steel sheet under different rotational field conditions. A novel two-dimensional measurement system was used. It consists of two perpendicular symmetrical yoke pairs arranged such that the magnetic field is highly homogeneous. The cross product of the H- and the B-vector was adopted as the correct estimation of the rotational power loss rather than the sum of the alternating losses in x-and y-direction. This approach was justified by means of measurements. A number of results are similar to the observations made earlier with rotational single sheet tester (RSST). However, no hard direction was observed for the non-oriented material, and the common RSST is questioned. Controlling H instead of B worked well.
