In various exemplary embodiments, as shown in the figures, the rotatable structure and the stationary structure can be closed-loop structures (e.g., having a ring or elliptical configuration). Colchon para el dolor de espalda . 11, the magnetic bearing mechanism comprising the bearing mechanisms 115 and 125 may further be configured to substantially maintain a relative axial positioning of the rotatable structure 110 and the stationary structure 120. For example, the magnetic field between the bearing mechanisms 115 and 125 may be sufficient to substantially prevent movement of either the rotatable structure 110 and/or the stationary structure 120 in the axial direction as a result of the force associated with the fluid current FC (e.g., the thrust of the fluid current) acting thereon.
In various embodiments of the present teachings, for example, one or more magnetic bearing mechanisms may be provided to substantially maintain the relative position, in an axial direction, of the rotatable structure and the stationary structure. For example, magnetic elements may be mounted to the stationary structure and the rotatable structure may be made of a ferrous material (or vice versa) such that the attraction force between the magnetic elements and the ferrous material could be sufficient to center and support the structures relative to each other. In various exemplary embodiments, in addition to bearing mechanisms configured to achieve magnetic levitation and/or as fluid bearing mechanisms, the present teachings contemplate the use of additional bearing mechanisms, including but not limited to, for example, rollers, low-friction pads (e.g., Teflon pads), etc. Moreover, bearing mechanisms in accordance with the present teachings may be configured to withstand a relatively harsh environment, such as, for example, underwater environments, by reducing the number of moving components and/or wear.
