Abstract: A slot-housed portion disposed on a radially inner side includes a first conductor portion and a second conductor portion having a higher electrical resistance per unit length than the first conductor portion, and has a higher electrical resistance per unit length than a slot-housed portion disposed on a radially outer side.

Abstract: A rotating electrical machine rotor core is implemented that can suppress an increase in number of manufacturing processes and has a magnetic structure that can reduce noise or vibration associated with rotation. A rotating electrical machine rotor core includes a member disposition hole in which a permanent magnet is disposed; and pair of magnetic flux limiting holes disposed on both sides in circumferential direction of each of magnetic poles, units in which member disposition hole is repeatedly made in circumferential direction being magnetic poles. Each magnetic plate includes plurality of types of through part pairs having different circumferential spacings between pair of limiting-hole through parts that makes pair of magnetic flux limiting holes.
