要約(英語): The influence of the shearing process on the iron loss of non-oriented electrical steels with thicknesses of 0.20-0.50mm was investigated. The deterioration of material iron loss was lesser in thinner steel sheets. The distribution of the increase in hardness near the sheared edge was almost half of the sheet thickness for all tested steels. Therefore, applying thinner steel sheets for the motor core may decrease the iron loss deterioration from the punching process. This argument was supported by measuring the iron loss of a model IPMSM using steels with different thicknesses and calculating the motor iron loss through FE analysis. The magnetic properties of narrow pieces corresponding to the width of the motor's teeth and yoke were shown to be important and useful to estimating the motor iron loss more accurately.
