Research on the structure design of a precision stage based on magnetic levitation technology and used in micro-electron manufacturing field
A new kind of stage which can be positioned accurately and quickly is presented in this paper. Magnetic levitation (maglev.)
linear drive and control technologies are applied in the stage. With a maglev system providing normal lift force and plane guiding force
the structure of the stage is simple and it can be controlled easily. By using linear synchronous motor
vibration caused by linear induction motor disappears
which benefits the maglev controlling system. Because of levitation and non-contact driving
there are no friction
wearing
metal particle
grease pollution and linking gap
and the total weight of the stage is lighter. All above improve its dynamic response frequency and the positioning accuracy. This stage meets the requirements of modern information industry to super-clean condition
high accuracy and high efficiency in micro-electron manufacturing field.
