摘要： In a stator core (1) support structure in a conventional rotating electric machine, it has been difficult to set the circumferential and radial stiffnesses with which elastic bars support a stator core (1), to appropriate values in view of a relationship between transmission of torque and vibration prevention. In order to solve the above problem, sectional shape of elastic support bars (6) is formed as rectangular, elliptic, rhombic or the like, and accordingly, the ratio between circumferential and radial stiffness of the elastic support bars (6) can be changed.

摘要： A permanent magnet type rotating electric machine is comprised of a rotor and a stator opposed to each other keeping a predetermined clearance therebetween. The rotor having a rotor core formed by silicon steel plates being laminated in an axial direction of the rotor core, slots being formed near an outer periphery of the rotor core in the rotor core so as to be open at the outer periphery of the rotor core, permanent magnets being inserted into the slots respectively, and a non-magnetic sleeve covering the outer periphery of the rotor core. Each of the slots has inclined side faces outwardly broadening the slot in a radial direction of the rotor core.
Each of the permanent magnets is fixed into the slot with a force applied from the sleeve so as to directing toward a center of the rotor core and an pressure applied from the inclined side faces of the slot.

摘要翻译： 永久磁铁式旋转电机由转子和定子以规定间隙相对的方式构成。 转子具有由硅钢板形成的转子铁心，所述转子铁心在转子铁心的轴向方向上层叠，在转子铁心中的转子铁心的外周附近形成狭槽以在转子铁心的外周开口 ，分别插入槽中的永磁体和覆盖转子芯的外周的非磁性套筒。 每个槽具有倾斜的侧面，该侧面在转子芯的径向方向上向外扩展槽。 通过从套筒施加的力将每个永磁体固定到槽中，以便朝向转子芯的中心和从槽的倾斜侧面施加的压力。
