Abstract
A sliding device with onboard moving-magnet linear motor is envisaged making the reciprocating stroke of a table longer, and enhancing the propulsion, high velocity and response of the table even with small in dimension, compact in construction and better in production efficiency. With the sliding device, a bed serves as a coil yoke while a table is as a magnet yoke. An armature assembly is composed of armature windings, a board on which the armature windings lie in juxtaposition, a wiring lying on the board and making connections with a power line to supply electric power to the armature windings, a protective sheet covering an overall surface of the armature windings and moldings of adhesive material to get the armature windings and connections of a power line with wiring closely adhering to the board.
