ABSTRACT:
A position-control stage system is disclosed, which may ensure much space to install the armature assembly on the bed, even with small in dimension. Correspondingly, the position-control stage system itself is made high in propulsion and efficient in operating performances including high-speed traveling, high response, high-precision position-control, and so on, even with compact or slim in construction. Armature windings to provide an armature assembly are made of three-phase coreless windings wound in annular flat configuration, and disposed on the bed radially outside of a rolling-contact bearing in a way closely adjacent to the bearing. Magnets to provide a field magnet array are each made in a segment, and disposed on the turntable in opposition to the armature windings in a way alternating in polarity circularly on a desired circular surface.
