Abstract
An electrical rotating machine including a stator core is provided. The stator core is formed of substantially sector-shaped sheet segments die-cut from electrical steel sheets and arranged in a circumferential direction of the stator core to form circular sheets which are stacked in an axial direction of the stator core. In the electrical rotating machine, end regions of the stator core are formed of stacked sheet segments die-cut from non-grain oriented steel sheets, and the other region of the stator core is formed of stacked sheet segments die-cut from grain oriented steel sheets.
