PROBLEM TO BE SOLVED: To provide a core for armatures which is easy to use, in a surrounding environment of high temperature or which is easy to use, in a surrounding environment that contacts a refrigerant. SOLUTION: Teeth 10 are arranged in a circular form around a rotating shaft P. A yoke 20 has a through-hole 21, and the through-hole 21 opens in a radial direction centered on the rotating shaft P, or in the axial direction which parallels the rotating shaft P. The teeth 10 passes through the through-hole 21. A reinforcing plate 30 is made of metal and is arranged axially facing the yoke 20. Moreover, the reinforcing plate 30 is welded/fixed to the teeth 10. COPYRIGHT: (C)2011,JPO&INPIT
