Abstract
An iron core including a laminate of a plurality of fixed electromagnetic steel sheets, a laminate of alloy thin strips which is sandwiched between the laminate of the electromagnetic steel sheets, a fastening mechanism which penetrates the laminates of electromagnetic steel sheets and alloy thin strips, and a fixing base. The laminate of alloy thin strips reduces compressive and torsional forces acting on the laminate of alloy thin strips by using the iron core having a structure in which upper and lower portions of a laminate of alloy thin strips having nanocrystal grains are sandwiched together with laminates of amorphous alloy thin strips. Furthermore, a motor including a rotor and the above-described iron core is used.
