Abstract: 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.

Abstract: 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.

Abstract: A slot coil 25 is inserted into a slot 23 provided in a stator core 21 and is covered with an insulating material 28. The insulating material 28 has an ear portion 29 on an outer circumferential surface thereof. The slot coil 25 is fixed to the stator core 21 by the ear portion 29 welded to an end surface 21b of the stator core 21.

Abstract: A rotor of a rotating electrical machine includes: a rotor shaft; a rotor yoke press-fitted to an outer circumferential portion of the rotor shaft; and a pair of end plates disposed on both axial sides of the rotor yoke. One end plate of the pair of the end plates is disposed between a plate fixing portion provided in the rotor shaft and one axial end surface of the rotor yoke, the plate fixing portion includes an inclined surface which is inclined such that an outer diameter size gradually increases as it goes away from the one axial end surface of the rotor yoke along a press-fitting direction of the rotor yoke, and an inner circumferential surface of the one end plate includes an inner circumferential inclined surface in contact with the inclined surface of the plate fixing portion.
