Abstract
A rotary electrical device includes a rotor having a hollow cylindrical shape or a solid cylindrical; and a stator having an annular shape and surrounding a rotation axis of the rotor. The stator includes a winding and a stator core constituted by a magnetic powder core. The stator core includes multiple cores facing each other with the winding interposed therebetween in an axial direction of the stator. One core of the multiple cores includes a yoke contacting another core, and one or more claw magnetic poles that protrude radially from the yoke toward the rotor. The one or more claw magnetic poles are alternately arranged with claw magnetic poles of the one other core. The yoke has a yoke surface parallel to the axial direction, contacting the other core.
