Abstract
A canned linear motor armature comprising an armature winding constituted by a coil group including a plurality of formed coils formed in a flat plate shape. A metal-made chassis is provided to surround the armature winding by a frame-like shape. A can hermetically closes two opening portions of the chassis. The coil group is interposed by a wiring board having a wiring portion and a resin-made frame of a bath tub shape. The frame is opened only at a face side of the wiring board. A periphery of the formed coils surrounded by the wiring board and the frame is configured to be injection-molded by a mold or a potting resin.
