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 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 fixture which secures a temperature detection element to a winding provided around a stator core of a motor, includes a main body to be inserted into a gap between the stator core and the winding, and an engagement portion formed on one end side of the main body on one side of the main body to engage with the rim of the opening of the winding. On the one side of the main body a recess is formed to house a temperature sensitive part of the temperature detection element. The depth of the recess is less than the maximum thickness of the temperature sensitive part of the temperature detection element.

Abstract: An electric motor includes a rotor including an iron core and a plurality of windings, and a stator including a plurality of permanent magnets forming a plurality of poles. The iron core has a plurality of primary teeth around each of which a winding is wound and a plurality of secondary teeth around each of which no winding is wound. The primary teeth and the secondary teeth are formed alternately with each other. The electric motor is configured such that a ratio between the number of poles formed by the permanent magnets of the stator and the number of phases formed by the windings of the rotor is 4m:3n (m and n are any natural numbers, excluding the case where m:n=2:3 is satisfied).
