Abstract
A magnet configuration comprising a pair of Halbach arrays magnetically and structurally connected together are positioned with respect to each other so that a first component of their fields substantially cancels at a first plane between them, and a second component of their fields substantially adds at this first plane. A track is located between the pair of Halbach arrays and a propulsion mechanism is provided for moving the pair of Halbach arrays along the track. When the pair of Halbach arrays move along the track and the track is not located at the first plane, a current is induced in the windings and a restoring force is exerted on the pair of Halbach arrays.
Claims29
A track, comprising at least one section of laminated sheets of slotted conductor, wherein said slots are terminated at their ends to provide a path for return currents.
A method for generating a restoring force upon a magnet configuration, comprising;
- providing a first Halbach array having a first magnetic field and a second Halbach array having a second magnetic field, wherein said first Halbach array and said second Halbach array are magnetically and structurally connected together to form a first pair of Halbach arrays, wherein said first Halbach array comprises magnet configurations positioned with respect said second Halbach array and said second Halbach array comprises magnet configurations positioned with respect said first Halbach array such that a first component of said first magnetic field and a first component of said second magnetic field substantially cancel at a first plane between said first Halbach array and said second Halbach array, and a second component of said first magnetic field and a second component of said second magnetic field substantially add at said first plane;
- positioning a track of windings between said first pair of Halbach arrays, wherein said track comprises at least one section of laminated sheets of slotted conductor, wherein said slots are terminated at their ends to provide a path for return currents.;
- and
- moving said first pair of Halbach arrays along said track, wherein when said first pair of Halbach arrays move along said track and said track is not located at said first plane, a current is induced in said windings and a restoring force is exerted on said first pair of Halbach arrays.
