ROTATING ELECTRICAL MACHINE

摘要

Provided is a rotating electrical machine using a permanent magnet, with improved reliability and wherein a magnet cover etc., does not come in contact with a rotor and broken pieces of permanent magnet or the magnet cover do not fly into the rotor side, even if there is distortion in magnetic cover or variations in dimension. The rotating electrical motor comprises a non-magnetic magnet holder configured by connecting a columnar section that holds the permanent magnet in the circumferential direction and an annular section that covers both side surfaces of the permanent magnet in the axial direction. An engagement section that engages with a locking section in the magnet cover is disposed on the outer diameter side of both side surfaces in the circumferential direction of the columnar section; and the inner diameter sides of both side surfaces in the circumferential direction of the columnar section have a gap (D) between same and the inner circumferential surface of the magnet cover, and are provided with an extending section that extends along the inner circumferential surface of the magnet cover.
