A rotor of a rotating electrical machine includes: a magnet; and a rotor yoke including at least a first core block and a second core block formed by stacking steel plates, each of the steel plates includes an opening portion serving as a coolant flow path, the opening portion positioned on an outermost diameter side includes an outer-diameter-side inner wall portion with a predetermined width in a circumferential direction and located on an imaginary circle centered on an axis of the rotor, the second core block is arranged adjacent to the first core block while the second core block is rotated by a predetermined angle with respect to the first core block, and the predetermined width is a length at which the outer-diameter-side inner wall portions of the opening portions of the first core block and the second core block overlap each other when seen from the axial direction.

Rotor of rotating electrical machine

The present invention is a core for a rotary electric machine comprising a stacked body where a plurality of shaping layers formed by solidifying a metal powder is integrally stacked.

Core for rotary electric machine and method of manufacturing the same

A slot coilis inserted into a slotprovided in a stator coreand is covered with an insulating material. The insulating materialhas an ear portionon an outer circumferential surface thereof. The slot coilis fixed to the stator coreby the ear portionwelded to an end surfaceof the stator core
