FIG. 4 is a partial sectional view of a magnet generator having a stator coil wound in a drum shape. 5 is a partial cross-sectional view of the stator coil formed of an annular winding, and FIG. 6 is a cross-sectional view taken along the line VI-VI of FIG. Now, the magnet synchronous generator is
Since the strength of the magnetic field is almost constant because the permanent magnet is used as described above, the induced electromotive force of the armature is proportional to the rotation speed. Therefore, it is applied to the power source of various actuator motors, the sub-exciter of the brush cis exciter, and the like.

As shown in FIG. 4, a stator coil 51 including a drum-shaped winding, that is, a winding wound in the shape of a diamond, is used in the slot of the stator core 1a arranged inside the frame 4. A magnet synchronous generator is composed of the coil 51 and the rotor composed of the rotating shaft 9 to which the permanent magnet 8 is attached.

There is a winding configuration consisting of a stator coil 52, which is an annular winding, whose cross section is shown in FIG. 6, wound around the circumference.

る。By the way, the above-mentioned synchronous generator main body is excited by a brushless exciter, and the brushless exciter is excited by a sub-exciter. It may be installed overhanging. As described above, when the magnet synchronous generator is mounted overhanging, it is important to reduce the size and weight of the rotating portion of the magnet synchronous generator. In recent years, a high-performance permanent magnet magnet made of a neodymium alloy has been developed, and it has become possible to reduce the size and weight of the field magnetic pole portion that constitutes a part of the rotating portion of the magnet synchronous generator. Therefore, in order to reflect the effect of reducing the size of the permanent magnet in the downsizing of the entire magnet synchronous generator, the coil length is shortened to reduce the axial length of the generator. There is a need.

電機の軸長を短くするのに不利な巻線構成である。In the structure of the stator coil of the conventional magnetic synchronous generator described above, the drum structure shown in FIG. 4 which is composed of a drum-shaped winding is wound in a plane while keeping a constant interval in the circumferential direction of the stator core 1a. Since it rotates, the coil end portion protrudes axially from the end of the stator core 1a, and the coil end length L
1 is long, and wasteful space is generated, which is disadvantageous for shortening the axial length of the magnet synchronous generator.

In the coil configuration including the annular winding shown in FIG.
Since the stator core 1b is wound between the slot 11 and the yoke 12 in a radial direction of the stator core 1b in the radial direction of the stator core 1b, as shown in FIG.
2 has the advantage that it can be made smaller than the coil end length L 1 formed of the hourglass winding shown in FIG.

Can shorten the axial length of the generator, but since the coil is concentrated and wound around the slot 11 of the stator core 1b, the coil end bulges and the coil end length is shortened. There was a problem that there was a limit.

The number of slots corresponding to is provided in the whole stator core. That is, a plurality of axially penetrating through-holes provided at equal intervals in the circumferential direction of the stator core end face are provided in the radial direction of the stator core, and the through-holes are respectively inserted into these through-holes. By forming a stator coil by conductively connecting the ends of the coil in the radial direction, the coil is dispersed throughout the stator core, and the coil is prevented from being concentrated and wound in the same slot. The bulge of the portion is eliminated, and the coil end length can be shortened. Therefore, the axial length of the generator can be shortened.

The drawings correspond to FIGS. 4 to 6 of the related art, respectively, and the same parts as those of the related art are denoted by the same reference numerals and detailed description thereof will be omitted. A stator core 1 installed in a frame 4 shown in FIG. 1 has an axial direction formed by stacking iron cores having a plurality of holes arranged at equal pitches in the circumferential direction by tightening with a tightening bolt (not shown). Two through holes 2 are provided in the radial direction. As shown in FIG. 2, a coil 5 is inserted into the through hole 2 formed in the stator core 1 in the axial direction of the stator core 1.

Thus, a winding structure including an annular winding in which a coil is spirally wound is formed. Further, the through holes 2 arranged in the circumferential direction of the stator core 1 are provided at equal pitches so that windings can be selected according to the number of magnetic poles.

定子コイル５の冷却効率を高めるようにしている。The coil 5 arranged in the through hole 2 of the stator core 1 has a cylindrical rod-shaped copper conductor provided with a tube made of a fluororesin having excellent slidability for insulation. The coils having the insulating coating are inserted into the through holes 2 to form the coil 5. In addition, the conductor that constitutes the coil 5 has a hollow cylindrical shape, and the outside air can be circulated in the hollow portion 5a (FIG. 3) to enhance the cooling efficiency of the stator coil 5.

電接続する構成となっている。Furthermore, the connecting conductor 3 for connecting between the coils 5 in the radial direction at the end of the stator core 1 is made of a copper plate, and as shown in FIGS. 2 and 3, the stator core 1 and the connecting conductor 3 are connected. Insulating plate 6 is attached to the end of stator core 1 for insulation between the three.
Are provided and mounted on the insulating plate 6. The ends of the coils 5 are arranged so as to pass through the insulating plate 6 and the connecting conductors 3, and both ends thereof are tightened axially in the axial direction with a predetermined pressure to make contact with the connecting conductors 31 to electrically connect the coils 5. It is configured to do.

Therefore, it is possible to make the length much shorter than the length of the conventional coil end portion in which the coil is concentrated and wound in one slot.

Although the example in which the stator coil is configured only by the two through holes provided in the radial direction has been described, in order to increase the number of windings of the coil 5 and increase the electromotive force, the capacity of the generator can be increased. This can be achieved by further providing through holes of a plurality of stages in the radial direction of the stator core 1, arranging coils through these through holes, and forming a winding structure in which the number of coil turns is increased.

The insulating material that coats the conductor is as thin as possible in order to increase the space factor of the conductor of the coil 5 arranged in the through hole 2 of the stator core 1, and the stator when inserted into the through hole 2 is as thin as possible. Any material can be used as long as it has durability against mechanical frictional force between the iron cores 1, and not limited to fluororesin, other organic material is applied to the conductor surface, or a tube is coated, or a composite of resin and fiber is used. A structure in which the material is wound can also be applied.

化を達成することができる。As described above, according to the present invention, a plurality of axially penetrating through holes provided at equal intervals in the circumferential direction of the end face of the stator core are provided in the radial direction of the stator core. The stator coils are formed by conductively connecting the coil end portions in the radial direction of the coils respectively inserted and provided in these through holes. Therefore, since the coils are distributed and arranged in the entire stator core, the coils are not concentratedly wound in the same slot,
The length of the coil end portion can be reduced. Therefore, the axial length of the magnet synchronous generator as the sub-exciter of the brushless exciter becomes short, so that the synchronous generator as a whole can be made compact and lightweight.

The cooling efficiency of the coil can be increased, further contributing to downsizing of the electric machine. Furthermore, in order to electrically connect between the stator coils at the iron core ends, an insulating plate is placed between the iron core ends and the stator coils, and the stator coils are screwed to the connecting conductors to connect the coils. Work can be done easily.
