    • A momentum wheel wherein friction has been substantially eliminated by replacing mechanical bearings with a magnetic suspension. The rotor of the momentum wheel, in the form of a circular disk whose diameter greatly exceeds its thickness, is maintained in suspension, free of physical contact with the housing, by means of magnetic fields applied between the circular flat surfaces of the rotor disk and a pair of stator plates. The rotor is passively restrained in the radial direction by means of permanent magnets, while an active axial restraint is provided by a combination of permanent magnets and electromagnetic windings.

    • A full levitation magnetic bearing system for support of a rotating body (71), such as a flywheel (92), about an axis of rotation includes passive radial magnetic bearings (70) that generate passive radial centering forces to counteract displacements of the rotating body (71) from its axis of rotation during rotation, and an axial actuator (102) for stabilizing the axial position of the rotating body (71). The passive radial magnetic bearings (70) include multiple concentric, radially spaced apart, axially magnetized ring magnets (73) on a stationary stator (72) and magnetically co-operating concentric pole rings (74) on a ferromagnetic end portion of a rotor (71). The rotor pole rings (74) are axially aligned with the magnet rings (73) when the rotor (71) is radially centered on the stator (72). Magnetic flux from the permanent magnet rings (73) passes directly across the airgap (78) between the axially facing surfaces of the magnet rings (73) and the rotor pole rings (74) and through rotating ferromagnetic section of the rotor (71), thereby generating both an axial attractive force and a passive radial centering force from the pole rings (74) tending to align with the stationary magnetized rings (73).
    • 用于围绕旋转轴线支撑诸如飞轮(92)的旋转体(71)的完全悬浮磁性轴承系统包括被动径向磁轴承(70),其产生被动径向定心力以抵消旋转体 (71),以及用于稳定所述旋转体(71)的轴向位置的轴向致动器(102)。 被动径向磁轴承(70)包括在固定定子(72)上的多个同心径向间隔的轴向磁化的环形磁体(73)和在转子的铁磁端部上的磁性配合的同心圆环(74) 71)。 当转子(71)在定子(72)上径向居中时,转子极环(74)与磁环(73)轴向对准。 来自永磁体环(73)的磁通直接穿过磁环(73)和转子极环(74)的轴向相对表面之间的气隙(78)和转子(71)的转动铁磁部分, 从而从倾向于与固定磁化环(73)对准的极环(74)产生轴向吸引力和无源径向对中力。

    • A magnetic bearing comprises permanent ring-shaped or disc-shaped magnets (4 to 7, 8 to 11), arranged in a corresponding manner on a rotor (1) and a stator (2) so that magnetic repulsion forces are generated providing passive stabilization of the rotor. At least one electric winding (14 to 18) is provided besides or between the permanent magnets (8 to 11) in particular of the stator (2), so as to generate a force component acting transversally with respect to the afore-mentioned repulsion forces. The permanent magnets (4 to 7) of the rotor (1) as well as the permanent magnets (8 to 11) of the stator (2) may be arranged respectively next to each other with respect to the rotational axis (3), so that there is an annular air gap extending in the axial direction. Hence, adjustable stabilization forces acting on the rotor (1) in the direction of the rotational axis (3) may be generated by means of annular windings (14 to 18). The windings (14 to 18) are controlled through an adjusting device (20) according to signals transmitted by a sensitive element (21), these signals corresponding to the axial gap of the rotor (1) with respect to its ordered position determined by the permanent magnets (4 to 7, 8 to 11). For a long rotor, such a bearing may be provided at each end of the rotor.
    • 磁性轴承包括以相应的方式布置在转子(1)和定子(2)上的永久性环形或圆盘形磁体(4至7,8至11),从而产生提供被动稳定的磁力排斥力 的转子。 在定子(2)的永磁体(8〜11)之间或之间设置至少一个电绕组(14至18),以产生相对于上述排斥力横向作用的力分量 。 转子(1)的永磁体(4〜7)以及定子(2)的永磁体(8〜11)可以相对于旋转轴线(3)分别相互配置,因此 存在沿轴向延伸的环形气隙。 因此,可以通过环形绕组(14至18)产生在旋转轴线(3)的方向上作用在转子(1)上的可调稳定力。 根据由敏感元件(21)传输的信号,绕组(14至18)通过调节装置(20)进行控制,这些信号对应于转子(1)的轴向间隙相对于由 永久磁铁(4〜7,8〜11)。 对于长转子,可以在转子的每个端部设置这样的轴承。
