Abstract:
1. A rotating electrical machine comprising: a rotor having an outer circumferential end; and a stator surrounding the outer circumferential end of the rotor with a gap provided therebetween, the rotor including: each of the first permanent magnets has a direction of magnetization in parallel with a radial direction of the rotor, the directions of magnetization of the first permanent magnets adjacent to each other in the circumferential direction are opposite to each other, each of the second permanent magnets has a direction of magnetization perpendicular to the radial direction, the directions of magnetization of the second permanent magnets adjacent to each other in the circumferential direction are opposite to each other, the first permanent magnet and the two second permanent magnets which are adjacent to the core piece have magnetic poles identical to one another on ends facing the core piece, and relative to a sum of an open angle of the core piece and an open angle of the second permanent magnet adjacent to the core piece in the circumferential direction, a rate of the open angle of the core piece is from 0.5 to 0.7.
