Abstract: An armature of a linear motor includes a winding wire; a core which is formed by laminating electromagnetic steel sheets and on which the winding wire is wound; and a binding member which is inserted into the core and which binds the core to a prescribed place. The binding member includes a locking part locked to the core, and a binding hole that does not penetrate the binding member and that is exposed from the core.

Abstract: A magnet plate includes a regulating member which is adapted to be press-fitted to a blind hole of a base plate. The regulating member protrudes from the surface of the base plate at one end, and prevents a permanent magnet from moving in a transverse direction. The regulating member has a narrower portion having a width smaller than the blind hole. Upon press-fitting of the regulating member, the base plate undergoes plastic deformation and the deformed portion moves into a space between the narrower portion and the inner wall of the blind hole.

Abstract: A method for producing a magnet plate for a linear motor is provided. The magnet plate comprises a base plate and a plurality of magnets juxtaposed to one another on a surface of the base plate. The method comprises providing the plurality of magnets on a surface of the base plate at a certain interval, placing the base plate into a mold, supplying a resin material into the mold, so as to form a resin molding covering the plurality of magnets on the surface of the base plate by means of injection molding, and magnetizing the plurality of magnets.

Abstract: A magnet assembly for a linear motor includes a cover member having weak magnetic properties, which covers one or more magnet plates, and a fixing mechanism for positioning the end parts 14c of the cover member directly above permanent magnets and detachably fixing the cover member to the magnet plate. The cover member has a first surface part covering a surface of the magnet plate which faces an armature and second surface parts continuous from the first surface part and covering side parts of the magnet plate. Furthermore, the fixing mechanism is provided on the second surface parts. Through the use of this magnet assembly for a linear motor, it is possible to minimize a rise of the cover member from the magnet plate without deteriorating workability at the time of installation or replacement of the cover member.
