Patent ID: 7633188

Claim:
A sliding device with onboard moving-magnet linear motor, comprising: an elongated bed of flat configuration, a table of flat configuration movable for reciprocation in a lengthwise direction by virtue of a linear motion guide unit, a field magnet of magnet segments lying on a first surface of the table opposite the bed in a way unlike magnetic poles are juxtaposed alternately in polarity in a traveling direction of the table, and an armature assembly having coreless armature windings of flat shape, which are installed on a second surface of the bed opposite the table in opposition to the field magnet in lengthwise direction, wherein the bed and the table are both made of magnetic material to provide magnet yoke and coil yoke for establishing magnetic circuits in part, wherein the armature assembly is composed of the 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, and an adhesive material cast around the armature windings to get the armature windings closely adhering to the board whose a lower surface is fastened immediately to the second surface of the bed, wherein end plates are fastened to forward and aft ends of the bed in a way coming into contact with ends of the board of the armature assembly to keep the table against falling away from the bed, and wherein the end plates are each made of a plate member bent into an L-shape in section and made with a recess to fit over the power line.
