JPS596150Y2 - Electromagnetic rail for linear thyristor motor with wave-shaped armature coil - Google Patents

Description

[Detailed Description of the Invention] The present invention relates to a linear thyristor motor electromagnetic rail used in ultra-high-speed railways or general transportation equipment.

Conventionally, electromagnetic rails for linear thyristor motors must mechanically withstand electromagnetic force and thermal stress, and electrically withstand commutation surges that occur between the coils.
It was produced by a certain form of P.

However, recently, with regard to wave-shaped armature coils, the vertical sides of the wave-shaped armature coils are sequentially arranged on both sides of the electromagnetic rail, with the aim of reducing the weight of the on-board field and reducing the excitation power.
A helical-shaped structure was invented, and along with this, the armature coil was fitted into a groove on the side of the core material.
It has now become possible to add strength to the core material.

Therefore, it is no longer necessary to use the costly one-body method.

Due to these circumstances, the present invention does not require a large mold, and the FR
The purpose of this invention is to provide a low-cost electromagnetic rail as claimed in the claims for utility model registration, which can omit the glass cloth lamination process and the like when forming one body of P.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be explained below with reference to the drawings showing embodiments of the invention.

FIG. 1 is a perspective view showing an embodiment of the structural parts of an armature coil unit, in which 1 is a coil conductor unit, which has half vertical sides 4 at both ends, and a conductor 2 made of copper or aluminum at both ends. It is covered with an insulating material 3 such as epoxy resin, except for the connecting portion 5.

6 is a core material made of an insulating material with excellent strength such as FRP, and has grooves 7 provided at each vertical pitch of the wave-shaped armature coil on both sides, and holes 8 for passing bolts, rivets, etc. There is.

Figure 2 shows an armature formed by fitting a predetermined number of coil conductor units shown in Figure 1 into the core material shown in Figure 1, and electrically connecting the opposing parts of the vertical sides from the top and bottom. It is a front view showing an example of a coil unit.

The upper coil conductor unit 16 and the lower coil unit conductor 17 face each other in grooves 13 provided on both sides of the core material 12 for each vertical pitch of the armature coil, and the opposing portions 14
are electrically connected by soldering or silver soldering or other methods to form a wave-shaped armature coil.

10 and 11 are terminal leads of the armature coil, and when the armature coil has 2n phases, 10 has n leads and 11 has n leads.

15 is a through hole for bolts, rivets, etc.

In this structure, the vertical side of the armature coil that generates the propulsive force is housed in the groove of the core material, so that the core material can receive the reaction force of the propulsive force.

FIG. 3 is a diagram illustrating an embodiment of the induction coil unit, and FIG. 3A is a front view and a sectional view taken along arrow A-A'.

The induction coil 20 is formed into a plate shape using an insulating material 21 such as epoxy resin to form an induction coil unit.

A through hole 22 for bolts, rivets, etc. is provided in the hollow part 23 of the induction coil.

In FIG. 3, there are two induction coils, but the number may be any number convenient for manufacturing.

FIG. 4 is a perspective view showing an embodiment of the support unit, in which a plate-shaped insulator 30 such as FRP is provided with through holes 31 for bolts, rivets, etc.

FIG. 5 is a diagram of an electromagnetic rail showing an embodiment of the present invention,
A is a front view and the opening is a cross-sectional view.

Reference numeral 40 designates an armature coil unit, and an induction coil unit 41 and a support unit 42 are arranged in contact with the lower part of the armature coil unit. , tighten with the tightening bolt 46.

47 is a washer.

The top plate 45 is fixed to the side plate by adhesive.

The tightening bolt 46 is made of FRP when eddy current loss is a problem.
It is sufficient to adopt the manufactured one.

As described above, the present invention includes a core material having grooves at each pitch of the vertical sides of a corrugated armature coil on both sides, and a core material having the vertical sides fitted into the grooves of the core material. An armature coil unit consisting of an armature coil conductor arranged in a helical shape, an induction coil unit consisting of an induction coil shaped into a plate with plastic material, a plate-shaped support unit, a support metal fitting, a side plate and a top plate. A wave-shaped armature, characterized in that a support unit is disposed in contact with the lower part of the armature coil unit and in contact with the lower part of the induction coil unit, and is tightened with side plates and support fittings on both sides. Since it is an electromagnetic rail for linear thyristor motors that has a coil, the reaction force of the propulsive force is received by the groove of the core material, and the reaction force of the levitation force can be transmitted to the road surface by the compression force of each unit.
It is mechanically strong, and since it is made into a small unit, the manufacturing equipment is cheaper than a single unit, and the manufacturing process is simplified, which has the advantage of being able to supply inexpensive electromagnetic rails. .
