    • The rotor 11 of an axial gap type motor 10 is provided with a plurality of main magnets 41 respectively magnetized in an axial direction of a rotational axis and disposed at predetermined intervals in a peripheral direction, a plurality of yokes 42 structured by a laminated member 71 produced by winding a tape-shaped electromagnetic steel plate 60 and respectively disposed on both sides of the main magnets 41 in the axial direction, and a rotor frame 30 made of a die-cast alloy and including a plurality of ribs 31 respectively interposed between the main magnets 41 adjoining each other in the peripheral direction and extending in the radial direction, and an inner cylindrical portion 32 and an outer cylindrical portion 33 respectively formed on the radially inner side of the ribs 31 and on the radially outer side of the ribs 31. According to this structure, the yokes structured by the wound laminated member and the rotor frame can be firmly unified with each other, thereby being able to secure such rigidity that can withstand a centrifugal force generated due to the rotation of the rotor and a magnetic suction force given from the stator.
    • 轴向间隙型电动机10的转子11具有分别沿旋转轴的轴向磁化并沿周向以规定间隔设置的多个主磁体41,由层叠部件71构成的多个磁轭42 通过缠绕分别设置在主磁体41的轴向两侧的带状电磁钢板60和由压铸合金制成的转子架30制成,转子架30分别插入在压铸合金中 主磁体41在圆周方向上彼此邻接并沿径向延伸,以及分别形成在肋31的径向内侧上和肋31的径向外侧上的内圆柱形部分32和外圆柱形部分33 根据该结构,由缠绕层叠构件和转子架构成的轭可以彼此牢固地一体化,从而能够 o确保能够承受由于转子的旋转产生的离心力和从定子给出的磁吸力的刚性。
