| 摘要 |
<p>In one aspect, the invention is concerned with a machine comprising: an annular stator-ring; an annular rotor-ring rotatable within or outside said stator-ring, and preferably at least substantially co-axial therewith; magnetic means, preferably comprising electromagnets; optionally first means for controlling electrical currents in said electromagnets, said magnetic means being provided such that and/or said first means controlling such that attracting magnetic forces are generated between said stator-ring and said rotor-ring increasing the static and/or dynamic stability of said rotor-ring and/or stator-ring preferably substantially.</p> |
