Abstract
A sliding system with onboard moving-coil linear motor is disclosed in which an armature assembly is a printed-circuit board, armature windings of flat configuration and coil stay having a stay and any number of cores made integral with the stay. The armature assembly is held by virtue of the stay at a preselected location inside an interval defined between field magnet arrays and, therefore, is small and compact in height in transverse section. A bed formed in an angled hook-like configuration in a transverse section contributes to shrinkage of the sliding system in either of height and width in transverse section or most compactness of the sliding system in transverse dimension. Moreover, the bed can be selected in length at discretion according to the purpose of usage to provide any desirable stroke length for a single table of a preselected length, getting the sliding system convenient for usage.
