STATOR

PROBLEM TO BE SOLVED: To provide a stator capable of reducing stress caused by a displacement difference during thermal deformation between a stator core and a casing, when the stator core and the casing are formed of materials different in coefficient of thermal expansion.SOLUTION: A stator includes: a cylindrical core that is formed of a material different in coefficient of thermal expansion from a casing; a ring-shaped member that is fitted into the outer periphery of the core; a fastening part that is formed or fixed in the ring-shaped member and that is fastened to the casing by a fastener; and a deflection part that is formed in the ring-shaped member and that absorbs a displacement difference between the casing and the core during thermal deformation. 【課題】ステータコアとケーシングとが熱膨張係数の異なる材料で形成される場合に、これらの間の熱変形時の変位差に起因した応力を低減することができるステータの提供。【解決手段】ステータは、ケーシングとは異なる熱膨張係数の材料により形成される円筒状のコアと、前記コアの外周に嵌合されるリング状の部材と、前記リング状の部材に形成され又は固定され、前記ケーシングに締結具により締結される締結部と、前記リング状の部材に形成され、熱変形時の前記ケーシングと前記コアとの間の変位差を吸収する撓み部とを含む。【選択図】図２
