CANNED LINEAR MOTOR ARMATURE AND CANNED LINEAR MOTOR

There are provided a canned linear motor armature and a canned linear motor capable of reducing an interface by reducing a number of parts of constituting members of an armature winding portion, capable of firmly carrying out injection molding and filling without involving air bubbles or the like by promoting an operability of the injection molding and filling by adopting a low viscosity resin and having a high long period insulation reliability of the armature winding against a refrigerant. In a canned linear motor armature, a coil group comprising a plurality of formed coils (71c) is interposed by a wiring board (71a) and a resin-made frame (71b) in a bath tub shape to be subjected to injection molding of a resin, further, a wiring portion (71e) is injection-molded or filled by a resin having a viscosity equal to or smaller than 30 Pa.s, a usable time period of 0.1 through 24 hours, and an elastic modulus equal to or smaller than 3,000 MPa.
