Method and apparatus for magnetically generating motion with high precision Patent uri icon

abstract

  • An apparatus includes first and second sections supported for relative movement, the first section having a plurality of first portions extending along respective different axes, and the second section having approximately annular second portions which each have a respective first portion extending movably therethrough to define a pair. Each portion can generate a magnetic field, the magnetic field generated by one of the portions of each pair being a function of an electrical signal. Interaction of the magnetic fields generated by the portions of each pair urge movement of the first portion relative to the second portion in a direction approximately along the axis of the first portion.
