One of them is to arrange a field pole on a bogie and It is known to use a linear synchronous motor in which an armature coil is arranged. Since such a permanent magnet type mover type structure is provided with a main power supply means on the ground, the weight of the on-board device is reduced,
Suitable for speeding up.

い。The use of superconducting magnets or electromagnets was initially considered as the structure of the on-vehicle field in the above-mentioned system, but the former has a problem that there are many leakage magnetic fields, while the latter consumes less power. At the present time, it has not been put to practical use because of the problems that it requires a large amount of electric power and a cooling device for the exciting coil.

る。Therefore, in recent years, a magnetic circuit for an on-vehicle field using a permanent magnet has been studied (for example, JR.
EA 1991 VOL.34 No. 1). As such a magnetic circuit, for example, a plurality of permanent magnets are fixed at predetermined intervals inside a yoke having a U-shaped cross section, and the armature coil moves relatively between the opposing permanent magnets. The structure having a magnetic gap is generally used.

That is, since the yoke for forming the magnetic path is made of a steel material having a large specific gravity, the weight of the magnetic circuit becomes large. Therefore, since the weight of the entire vehicle including the traveling carriage becomes large, there is a problem that the acceleration performance cannot be improved and the speed can not be increased unless the current supplied to the armature coil installed on the ground is increased.

On the side edges of the mover body 1 in the longitudinal direction, cavities 2 into which block-shaped permanent magnets to be described later are fitted are provided at predetermined intervals.

The permanent magnet 4 is magnetized in the thickness direction, and is fixed to the yoke 3 so that magnetic poles of different polarities face each other via a magnetic gap 4a and different magnetic poles appear in the longitudinal direction.

That is, the yoke 3 having the permanent magnet 4 fixed on the surface is moved in the direction of the arrow so as to face the side edge portion in the longitudinal direction of the mover body 1, and the permanent magnet 4 is moved to the space 2 provided in the mover body 1. It may be assembled so as to be fitted. After assembly, the yoke 3 is fixed to the mover body 1 via a fastening member (not shown) such as a screw.

It is also possible to have a maximum magnetic energy product above R-Fe-
It is desirable to use a B-based magnet (where R is one or more rare earth elements such as Nd and Pr).

できるという効果がある。With the above construction, since a pair of flat plate-shaped yokes 3 is used in the magnetic circuit, the weight is smaller than that of the conventional construction, and the weight can be reduced. Further, the mover having the above configuration can be easily assembled by simply inserting the pair of yokes 3 to which the permanent magnets 4 are fixed to the side edge portions of the mover body 1, so that the number of assembling steps can be significantly reduced. There is an effect that can be.

危険を伴うという問題点がある。However, it was clarified by the subsequent examination that there were some problems. First, since the permanent magnet 4 is made of a magnet material having a large maximum magnetic energy product as described above, when the distance between the facing surfaces of the permanent magnet 4, that is, the magnetic gap is, for example, 85 mm, The magnetic flux density in the thickness direction is an average of 5000
More than G, up to 6600G. Therefore, in the case of assembling as shown in FIG. 9, the attraction force acting between the opposing permanent magnets 4 and 4 becomes large, which makes it difficult to insert the yoke 4 into the mover main body 1 and the assembling work. There is a problem in that it is dangerous.

である。Of course, when the yoke 3 is inserted, a spacer (not shown) made of a non-magnetic material is provided inside the mover body 1.
Although the work is done with the interposing, the spacer is firmly sandwiched by the permanent magnets 4 and 4,
It may be difficult to remove the spacer. In addition, it is the current situation that the yoke 3 is disassembled from the assembled state in the same manner as described above. These are due to the extremely large attraction force acting between the opposing permanent magnets 4, 4.

With the size set larger than the magnetic gap to be formed between
It is interposed between the permanent magnets 4 and 4 fixed to the yoke 3. In this case, since the attractive force acts between the permanent magnets 4 and 4, the parallel surface of the outer end of the movable member 5 is in contact with the facing surface of the permanent magnet 4 and is sandwiched.
