摘要:
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.
摘要:
A magnetic plate for a linear motor, a linear motor having the magnetic plate, and a method of manufacturing the magnetic plate, wherein the strength of a portion where the thickness of a resin layer is small is improved, while maintaining desired thrust force of the motor. A woven cloth such as a glass woven cloth or a carbon fiber woven cloth is attached on a surface of a plurality of permanent magnets, wherein N-poles and S-poles of the permanent magnets are alternately positioned. Then, a resin protecting layer is formed on the woven cloth by resin molding.
