Abstract
Disclosed a slider unit having built-in a moving-coil linear motor made compact in construction by the provision of an improved magnet yoke for supporting field magnets, which is made in a slim construction, nevertheless very high in stiffness. The magnet yoke is comprised of a pair of confronting webs and a connecting web to connect integrally the confronting webs to each other. The magnet yoke of such integral construction helps ensure the overall high stiffness despite the webs being made thin. Thus, the magnet yoke may be made considerably slim, compared with the prior magnet yoke in which the confronting webs and connecting web are produced individually. A moving-coil assembly is installed to a table movable in a sliding manner through linear motion guide units with respect to a stationary bed.
