Abstract: The present invention discloses a magnetic suspension bearing, it comprising: an outer layer which encloses a plurality of magnets and is made of magnetic material, an inner layer which encloses a plurality of magnets and is made of magnetic material, an outer enclosure which is located at one side of the outer layer and encloses the outer layer to form a magnetic barrel, and an inner enclosure which is located at one side of the inner layer and encloses the inner layer to form a magnetic barrel. As mentioned above, when assembling the bearing, the outer layer and the inner layer are assembled together, and the magnets in the inner layer and the outer layer are disposed staggeringly up and down, remaining a gap between each pair of the magnets so as to generate a magnetic suspension force produced from repulsion force between magnets of the same polarity. With this magnetic suspension bearing, the shaft is able to rotate with high speed yet less generation of heat by friction, due to a gap between an upper end and a lower end of the inner and outer layer the magnets therein will not impact each other even if vibration therebetween is more than a limit, and the outer enclosure and the inner enclosure as magnetic barrels encloses the outer layer and the inner layer so that some components are protected from magnetic force generated by the magnets, which improve the durability of the bearing compared with a conventional pivot or ball bearing.

Abstract: A pseudo-Ievitation permanent magnet repulsive bearing and drive system arrangement for a large diameter, hollow centre composite flywheel for multi megawatt hours energy storage. The magnets are positioned in a frustrated cone to assist in centralising the running axis. The levitation system functions utilising multiple concentric rings of prime numbers of repulsive permanent magnets. Diaphragms, which deflect vertically and radially in concert with the flywheel as it speeds up, transmit torque between the flywheel and its drive system via a central drive shaft which rotates within active magnetic bearings or other bearing types. The lower fixed magnet arrays are elongated such that the cylindrical rotating magnets do not overhang at either end of the fixed magnet as the flywheel expands due to centrifugal force.

Abstract: An apparatus (1) for rotational motion about a rotational axis (14) of a first member (2) relative to a second member (3), the first member having an outer surface being rotational symmetric about the rotational axis, and the second member having a corresponding rotational symmetric cavity with an inner surface accommodating at least part of the first member with an interspace between the outer surface of the first member and the inner surface of the second member. A repulsive magnetic field (4) between the first and the second member prevents contact between the outer surface of the first member and the inner surface of the second member. This magnetic field is achieved by a plurality of permanent dipole magnets (6, 13) arranged in the first member and in the second member with identical polarity (7) directed towards the interspace between the first and the second member. By using a plurality of magnetic dipoles an arbitrary shape can be provided with a surface having only north or south poles of magnets. The inventions is especially suited for rotational support of Darrieus-type wind turbines (20).

Abstract: A bearing (11) with permanent magnetic elements (18) which are arranged in a rotating and a not-rotating annular series (12, 13). The rotating series (13) are connected to or integrated with a rotating element. A gap (a) is maintained between said two series of magnetic elements due to the repulsive force acting between them. Such a bearing is particularly suitable at hubless propellers for ships, electric generator turbines and pumps. Improvement is achieved by providing at the mutually rotating annular series (12, 13), that the permanent magnetic elements (18) each is accommodated in a magnet holder (15) of ferromagnetic conductive material, said elements (18) being arranged in recesses (16, 21, 22) in the magnet holder (15) of ferromagnetic conductive material.

Abstract: A ferromagnetic shield in contact with a magnet bar at the opposite end from the working surfaces of the bar eliminates the field canceling effects that arise from the Amperian currents at that end. The optimum polarization direction for such bars is one that is parallel to the azimuthal coordinate of the bar. The field at the working surface of the bar approaches that of a bar of infinite length because the shield, located on the side opposite to that of the working surface, completely eliminates, or at least substantially reduces, the field cancelation effect that normally would occur. The magnet bars with shields can be assembled on rotors and stators in flywheel storage systems and other rotating machinery.
