摘要： With a view to reduce vibrations generated by a motor and improve resistance to heat, reliability and vibration isolation properties without increasing the cost or the number of manufacturing steps in a rotor for a permanent-magnet motor, a rotor core is formed of an outer peripheral portion by which the permanent magnet is fixed, and a central portion by which a shaft is fixed, a clearance is provided between the outer peripheral portion and the central portion, and the outer peripheral portion is connected to the central portion by means of a plurality of fastening members. Thus, a rotor having excellent vibration isolation properties can be obtained. Since the rotor core is formed of laminated iron plates on which the outer peripheral portion, the central portion and the fastening members are all formed as one piece, resistance to heat, reliability and the vibration isolation properties can be enhanced without increasing the cost or the number of manufacturing steps.
摘要翻译：为了减少电动机产生的振动，提高耐热性，可靠性和隔振性能，而不增加用于永磁电动机的转子的成本或制造步骤的数量，转子铁芯由外周固定永磁体的部分和固定轴的中心部分，在外周部分和中心部分之间设置间隙，并且外周部分通过多个连接到中心部分的紧固件。因此，可以获得具有优异的隔振性能的转子。由于转子铁芯由外周部分，中心部分和紧固部件全部形成为一体的层压铁板形成，因此可以在不增加成本的情况下提高耐热性，可靠性和隔振性能制造步骤数量。

摘要： A hermetic motor compressor comprises a casing which includes a dome-like upper casing and a dome-like lower casing. Each of the upper and lower casings has an engagement portion for telescopically engaging with each other. The stiffness of the upper casing is increased by making at least three corner portions close to the engagement portion. Crescent-shaped portions, curved surfaces, an apex portion and crest lines are also provided for the upper casing. This specific structure of the upper casing may be made also for the lower casing, and when both of the upper and lower casings have such construction, the corner portions of the upper casing and the corner portions of the lower casing are arranged alternatively so that the vibrating modes of respective casings offset each other. The shape of the entire casing may be spherical or ellipsoidal.
摘要翻译：封闭式电动机压缩机包括一个包括一个圆顶状上壳体和一个穹顶状下壳体的壳体。上壳体和下壳体中的每一个具有用于彼此可伸缩地接合的接合部分。通过使至少三个角部靠近接合部来增加上壳体的刚度。上壳体也设有月牙形部分，弯曲表面，顶部和顶部线。上壳体的这种具体结构也可以用于下壳体，并且当上壳体和下壳体都具有这样的结构时，上壳体的角部和下壳体的角部被交替地布置，使得各个壳体的振动模式彼此抵消。整个外壳的形状可以是球形或椭圆形。
