 note = {The motor core is usually manufactured from magnetic steel sheet with press machine. However, usually most parts of the plate are scalped, and only about 16% of the sheet is used for the core. The spiral accumulating core system is suitable for manufacturing the core more ecologically because in this system more than 50% of the magnet steel sheet can be used. In this study, a unit cell model is assumed considering periodic character of the actual core under plane strain condition in the z direction. Using this simple model, the effects of the diameter and width of the core are discussed. Also, the effects of the numbers of the slit and embossing interlocking are analyzed. It is found that around the slits the core should be considered as zero elastic modulus because no tangential stress exists. Also, a simple evaluation method is proposed to estimate the effective elastic modulus by applying the rule of mixture to the simple model.},
