Beschreibung
Zusammenfassung:	A permanent magnet embedded motor includes a cylindrical stator core disposed on an inner side of a cylindrical frame and configured by stacking a first annular core and a second annular core disposed to be adjacent to the first annular core in an axial direction of the frame, and a rotor disposed on an inner side of the stator core. The second annular core is fixed to the first annular core by using swaging portions formed in the second annular core, and adjacent first yokes are in contact with each other, while adjacent second yokes are separated from each other.
