本発明はリニアパルスモータに関し、特にリニアパルス
モータの可動子に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a linear pulse motor, and particularly to a mover of a linear pulse motor.
従来のリニアパルスモータの可動子は薄板の磁性材料表

的であった。The mover of a conventional linear pulse motor has a lattice-shaped magnetic pole tooth plate with slits removed by press punching or chemical etching on the surface of a thin magnetic material, which serves as a base flat magnetic path and strength reinforcement. The common methods for manufacturing a mover include bonding it to a magnetic path plate, and half-etching a slightly thick magnetic material using chemical etching to form magnetic pole teeth.

あった。When a conventional thin lattice-shaped magnetic pole tooth plate is adhered to a magnetic path as a base material and a magnetic path plate for the purpose of improving strength, the thickness of the adhesive interposed between the magnetic pole tooth plate and the magnetic path plate Due to non-uniformity, shrinkage of the adhesive itself when it hardens, and the fact that the magnetic pole tooth plate and the magnetic path plate are fixed with adhesives with different linear expansion coefficients, the magnetic pole may deteriorate over time or due to temperature changes. There were drawbacks such as warpage and cracking of the tooth plates, and the adhesive itself was prone to cracking.

あった。Furthermore, in the method of constructing a mover by etching a thick magnetic material, machining distortion remains on the surface of the base material at the stage of flattening the base material before etching. Therefore, if a slit is formed by etching only on one side, the balance of machining strain between the etched side and the non-etched side will be disrupted, causing warpage in one direction, and ensuring sufficient strength. If the shape of the base material is determined so as to have the shape of the base material, there is a drawback that the weight of the mover increases.

している。The mover of the linear pulse motor of the present invention is made by overlapping a lattice-shaped magnetic pole tooth plate made of a thin plate of magnetic material with a magnetic path plate that serves as reinforcement for mechanical strength and a magnetic path, and integrally molded with synthetic resin. Then, connect holes in the resin encapsulated in the magnetic path plate so that the entire groove between the magnetic pole teeth, the entire outer periphery of the magnetic pole tooth plate, and the synthetic resin encapsulated and embedded in the back and outer periphery of the magnetic path plate are connected and fastened over the entire area. have.

防ぐためである。Referring to FIGS. 3A and 3B, the magnetic path plate 5 has a through hole 9 formed therein. One side of the magnetic pole tooth plate 1 is held down by a flat plate, and the magnetic path plate 5 is accurately positioned on the other side.
Melted synthetic resin is poured in. The synthetic resin flows into the groove of the magnetic pole tooth plate 1 through the through hole 9 of the magnetic path plate 5, solidifies, and hardens the outer periphery of the magnetic pole tooth plate 1 and the magnetic path plate 5 to form the bridge portion lO~
18 and fixed. This results in the mover shown in FIGS. 1A and 1B. Referring to the figure, through hole 9
are arranged so as to cover all the grooves 3. According to this configuration, the synthetic resin flows into all the grooves 3 from the through hole 9 and fills the grooves 3. This is to prevent dust from accumulating during use and interfering with the movement of the mover by filling the groove 3.

Furthermore, this connected part (bridge part) also has the effect of increasing the mechanical strength of the mover.

させる効果がある。As explained above, the present invention is to integrally mold a magnetic pole tooth plate in which the magnetic pole teeth are formed of a thin magnetic material with a synthetic resin in a state in which mechanical strength reinforcement and a magnetic path plate that also serves as a magnetic path are tightly joined. Since the bonding in the board thickness direction is performed by the synthetic resin crosslinking parts 10 to 18, the mechanical strength and magnetic properties are sufficiently satisfied, and the mass of the mover itself is compared to that of a mover integrally made of magnetic material. This makes it possible to reduce the mass to 1/2 or less, which has the effect of significantly improving the high-speed response of the linear pulse motor.
