抄録

As a high performance motor core, spiral cores made of grain-oriented electrical steel sheets (GO) were developed. All the teeth directions are coincident with the GO rolling directions (easy magnetization axis ) in the spiral cores. The GO spiral cores have excellent properties, because the GO has a very low iron loss and a very high permeability in the rolling direction. In the GO spiral cores. the iron losses decrease to a quarter and the inductions are 0.2 T higher at 800A/m compared with conventional spiral cores usually of SPCC. The thickness of conventional spiral cores generally changes, and the applications are limited to automobile alternator cores. The thickness of GO spiral core scarcely changes during a spiral deformation, because the core sheets are deformed in the transverse direction to the rolling direction of GO, that is <110> {Oll}. and the <110> {011} deformation of Fe does not bring about the sheet thickness. As the stiffness and the packing factor of a GO spiral core are high in the sake of no thickness change. GO spiral cores have high performance for motor cores.
