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.

First claim

The invention claimed is:

1. A method for producing a magnet plate for a linear motor, the magnet plate comprising a base plate and a plurality of magnets juxtaposed to one another on a surface of the base plate, the method comprising:
providing the plurality of magnets on the surface of the base plate at a certain interval such that there is direct contact between the plurality of magnets and the base plate;
placing the base plate into a hollow portion of 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,
wherein the base plate is a rectangular plate having a length, a width and a height, the height smaller than the length and the width, wherein a first surface of the base plate is established on a side normal to a direction in the height direction, and wherein the magnets are directly supported on the first surface of the base plate, and
wherein the magnets are rectangular magnets, the magnets having a length, a width and a height, the respective heights of the magnets smaller than the respective lengths and respective widths of the magnets, wherein a second surface is established on a side of the magnet normal to a direction in the height direction of the magnet, and wherein the second surface is parallel to the first surface.

2. A method for producing a magnet plate for a linear motor, the magnet plate comprising a base plate and a plurality of magnets juxtaposed to one another on a surface of the base plate, the method comprising:
providing the plurality of magnets on the surface of the base plate at a certain interval such that there is direct contact between the plurality of magnets and the base plate;
placing the base plate into a hollow portion of 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,
wherein the base plate is a rectangular plate having a length, a width and a height, the height smaller than the length and the width, wherein a first surface of the base plate is established on a side normal to a direction in the height direction, and wherein the magnets are directly supported on the first surface of the base plate.

3. A method for producing a magnet plate for a linear motor, the magnet plate comprising a base plate and a plurality of magnets juxtaposed to one another on a surface of the base plate, the method comprising:
providing the plurality of magnets on the surface of the base plate at a certain interval such that there is direct contact between the plurality of magnets and the base plate;
placing the base plate into a hollow portion of 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,
wherein the hollow portion of the mold is a rectangular hollow portion, and wherein the base plate is a rectangular base plate having proportional dimensions to the hollow portion.
