Abstract

The magnetic properties of a motor core are affected by the distortion due to the compression caused by bolt bundles. There have been few reports of such behavior being investigated systematically, although detailed examination of the behavior of magnetic properties is important. In this paper, the correlation between the compressive force of a silicon steel sheet and its magnetic properties is measured, using some single sheets compressed in the thickness direction. A special jig was prepared, and the magnetic field strength in the compressed region was measured using a Rogowski coil. The detailed behavior of the deterioration of the BH curve the iron loss due to cutting, and the compression caused by bolt bundles are illustrated.
