Abrégé

An improved passive magnetic bearing (PMB) for rotating machineries and rotating machineries integrating the bearing are configured to counteract the three states dimensional forces applied on them when put in an operating environment having external forces. The improved PMB includes a first ring element having a Halbach array. A second ring element has first and second Halbach arrays extending angularly over respective regions of the second ring. Magnetic interaction from the Halbach array of the first ring with the first and second Halbach arrays of the second ring when the rings are positioned relative each other within an axial operating range defines a combined force curve. This curve can have an axial component matching a predetermined target axial force curve and a radial component matching a predetermined target radial force. In one application, one or more passive magnetic bearings can be integrated in energy producing turbines, whereby the axial component of the force counteracts flow force in a torque generating direction and the radial component counteracts gravitational forces.
