    • A rotating electric machine that can be improved in cooling performance is provided. An end plate includes an annular plate portion arranged to be spaced from a rotor in an axial direction and secured to a rotation shaft, and a tubular portion protruding from an outer edge of the annular plate portion to abut on an axial end surface of the rotor. A partition plate arranged between the rotor and an end plate forms a first space between the rotor and the partition plate and a second space between the annular plate portion and the partition plate. A communication passage allowing the first space and the second space to communicate with each other is formed in the partition plate at a radially outer side relative to a permanent magnet. A through hole extending through the annular plate portion in the axial direction is formed in the annular plate portion at a radially inner side relative to the permanent magnet.
    • 提供了可以提高冷却性能的旋转电机。 端板包括环形板部分,其被设置为沿轴向方向与转子间隔开并固定到旋转轴;以及管状部分,其从环形板部分的外边缘突出以抵靠转子的轴向端面 。 布置在转子和端板之间的隔板在转子和隔板之间形成第一空间,并且在环形板部分和隔板之间形成第二空间。 在第一空间和第二空间相互连通的连通通道相对于永磁体形成在隔板的径向外侧。 在环形板部分中,相对于永磁体在径向内侧形成有沿轴向延伸穿过环形板部分的通孔。

    • A laminated core includes a laminated body, clamping plates and holding members. The laminated body includes a plurality of amorphous alloy plates, which are stacked one after another in a stacking direction such that each adjacent two of the plurality of amorphous alloy plates directly contact with each other. The clamping plates contact opposed end surfaces, respectively, of the laminated body in the stacking direction. A thickness of each of the first and second clamping plates in the stacking direction is larger than that of each of the plurality of amorphous alloy plates. Each holding member contacts with the clamping plates and maintains a predetermined space between the clamping plates while the laminated body is clamped between the clamping plates.
    • 层叠铁芯包括层压体,夹紧板和保持构件。 层叠体包括多个非晶合金板,它们在堆叠方向上一个接一个地层叠,使得每个相邻的两个非晶合金板彼此直接接触。 夹紧板分别在堆叠方向上接触层叠体的相对端面。 层叠方向上的第一和第二夹板的厚度大于多个非晶合金板的厚度。 每个保持构件与夹紧板接触,并且在层叠体夹在夹板之间时,在夹持板之间保持预定的空间。
