Abstract
A sliding device is provided which is convenient for manufacturing at high production efficiency the small sliding device, which meets the requirements for high propulsion, high response and long traveling stroke. The sliding device includes a field magnet of eight poles lying on the table, and an armature assembly of twelve coreless armature windings of rectangular shape, which are installed on the bed in opposition to the field magnet. The table is made with a recess sinking by a depth not more than a thickness of the field magnet to make it easier to set in place the field magnet.
