Title: ROTOR AND ROTATING ELECTRIC MACHINE
Abstract:
In a rotor (3) that has: a rotor iron core (30) having a plurality of insertion holes (7) formed so as to pass therethrough in the axial direction Y and to be spaced apart in the circumferential direction (X); and a magnet (6) provided in each of the insertion holes (7), hole-inner circumferential surfaces (81) of the insertion holes (7) and magnet-inner circumferential surfaces (91) of the magnets (6) are not in contact with each other and form spaces (51, 52) therebetween, adhesive layer sections (11, 12) are formed between hole-outer circumferential surfaces (80) of the insertion holes (7) and magnet-outer circumferential surfaces (90) of the magnets (6), the hole-outer circumferential surfaces (80) of the insertion holes (7) and the magnet-outer circumferential surfaces (90) of the magnets (6) with which the adhesive layer sections (11, 12) are in contact are formed in a planar shape, and the widths (T1, T3) of the spaces (51, 52) in the radial direction (X) are larger than the widths (T2, T4) of the adhesive layer sections (11, 12) in the radial direction (X).
