Abstract: Provided is a segment-core coupled body, including a plurality of segment cores each including a core back and a tooth; and a plurality of coupling portions configured to couple the core backs to one another, wherein the plurality of segment cores and the plurality of coupling portions are each a laminated body of magnetic sheets, wherein the plurality of coupling portions each include: a posture holding portion adjacent to a gap defined between adjacent core backs; a first thin portion configured to couple one corner portion of the adjacent core backs and the posture holding portion; and a second thin portion configured to couple another corner portion of the adjacent core backs and the posture holding portion, and wherein, the posture holding portion projects toward a radially outer side with respect to the adjacent core backs.

Abstract: This disclosure discloses a rotating electrical machine comprising: a stator; and a rotor; one of said stator and said rotor having a coil, the other having a plurality of magnetic pole units each forming first and second magnetic poles configured to be aligned alternately and to have mutually opposite polarities at a side of the one of said stator and said rotor, each of said magnetic pole units comprising: a unit core that a projecting part configured to protrude toward the side of the one of said stator and said rotor is formed; and a permanent magnetic provided between each of said projecting parts on the side of the one of said stator and said rotor from said unit core, said first magnetic pole being formed by said permanent magnet, and said second magnetic pole being formed by each of said projecting parts.
