PROBLEM TO BE SOLVED: To provide a core that keeps a gap evenly between a rotor and a stator, and also to provide a rotating electrical machine using the same. SOLUTION: In a rotating electrical machine, the core is used in a rotor 5 and a stator 3 disposed opposite each other via a gap in the axis direction that is a direction of the rotating axis. The core used in the stator 3 is equipped with an iron core 31 and a holding member 30, wherein the iron core 31 is made by stacking a plurality of thin plates in parallel to the rotating axis while being wound around the rotating axis to have a first face 31a on the gap side of the rotating axis and a second face 31b on the opposite side from the gap, and the holding member 30 holds at least the second face 31b. The second face 31b of the iron core 31 and the holding member 30 are joined by welding via the holding member 30. COPYRIGHT: (C)2010,JPO&INPIT |
