PROBLEM TO BE SOLVED: To obtain a coreless linear motor wherein an armature can be efficiently assembled and the radiation performance is not impaired. SOLUTION: The coreless linear motor includes: a stator 2 having a magnet attachment seat 10 having a recessed sectional shape; and a moving member 1 that is placed between the inner walls of the magnet attachment seat 10 and moves in the direction along the inner walls. The moving member 1 is formed by integrally molding an armature winding 4 comprised of multiple coils arranged in the direction of movement of the moving member 1 and an armature attachment seat 3 with the armature winding 4 attached thereto with resin 6. The stator 2 is formed by disposing multiple magnets 11 on each inner wall of the magnet attachment seat 10 so that their magnetic poles adjoining in the direction of movement are different from each other. The armature attachment seat 3 has a recessed portion 7 for housing the armature winding 4 and an armature connecting portion 5. The recessed portion 7 is formed by fitting the armature attachment seat 3 and an A member 8 and a B member together. COPYRIGHT: (C)2009,JPO&INPIT
