機として使い、励磁機なしの構造としている。For brushless synchronous machines, for example, in patent No. 801990, which was invented by the present inventor, the internal connection of the armature winding is a three-phase double star connection, and the windings of each phase are connected in parallel when viewed from their external connection terminals. three windings of each phase to form one star-shaped three-phase connection, and the other three windings to form the other three-phase star connection.

又効率を悪くすることになる。However, such synchronous machines also have problems. In other words, in this type of synchronous machine structure, there are two types of rotor windings: an excitation winding that is electromagnetically coupled to the stator winding as a rotor winding, and a field winding that receives excitation power from this excitation winding via a rectifier. windings of different types shall be provided on the rotor. Therefore, the rotor is made large, resulting in a structure that is difficult to use. Therefore, in order to minimize the number of devices installed on the rotor and create a highly usable and efficient synchronous machine structure, the patent application No. 13 was filed in 1988.
In No. 0604, one type of winding installed on the rotor is used for excitation and field at the same time, but even with this, the known patent No. 801990 has one major drawback. That is, in Patent No. 801990, the three-phase double star connection constituting the armature winding is simply a combination of two star connections, and in each star connection, an excitation DC current is provided to the armature winding. Since the direction of the current is simultaneously directed from the neutral point to the three external connection terminals on the one hand, and from the three external connection terminals to the neutral point simultaneously on the other hand, the current created by the excitation current in each star-shaped connection is This results in mutual reduction of magnetic forces. For that purpose, patent No. 80
In No. 1990, the stator armature winding used for excitation was poorly utilized, and the device could not be simplified or reduced in size.
Moreover, the efficiency will be deteriorated.

It is in.

してだけではなく、励磁機をも兼用することになる。While Fig. 1 mainly shows the stator winding, Figs. 2 and 3 show the rotor winding 43 used in combination with Fig. 1.
and 44 are shown. Rotor windings 21 and 22 and 23 and 2
4 are connected in series, and windings 21 and 22 are connected in series, and 23 and 24 are connected in series.
are connected in parallel, and their main terminals 25 and 26
is connected to the AC side terminal 45 of the forward converter 20, and the DC side output terminals 27 and 28 of the forward converter 20 are connected to the winding 2, respectively.
It is electrically connected to an intermediate terminal 41 between windings 1 and 22 and an intermediate terminal 42 between windings 23 and 24. In the case of Figure 2, windings 21 and 22
In principle, the series connection of the windings 21 and 23 and the series connection of the windings 23 and 24 are arranged as a single phase.
The combination of the windings 22 and 24 may be a two-phase combination. Considering the case where the rotor winding 43 of FIG. 2 rotates together with the rectifier constituting the forward conversion device 20 in opposition to the stator armature winding 13 of FIG. 1, the following will occur. That is, the direction of the electromotive force induced in the rotor winding 43 corresponding to the excitation current shown by the solid line arrow flowing in the stator winding 13 or the direction of the current flowing therein is shown by the dotted line arrow,
The direction of direct current flowing into the winding through the forward converter 20 due to the electromotive force is indicated by a solid arrow. In order for electromagnetic interaction to occur between the stator winding 13 in FIG. 1 and the rotor winding 43 in FIG. The number of magnetic poles created by the current must be equal to the number of magnetic poles created by the current flowing through the rotor winding 43 and indicated by the dotted arrows. For example, suppose this is 8 poles. Therefore, the stator winding 13 corresponds to the four field poles created by the direct current indicated by the solid line arrows flowing through the rotor winding 43.
A voltage is induced in the direction of the dotted arrow, which causes it to operate as a four-pole machine. The number of magnetic poles produced by the current indicated by the dotted arrows in the stator winding 13 must be four in this case. The electric machine action that can be considered between the stator armature winding 13 in FIG. 1 and the rotor winding 43 in FIG. This is based on the well-known fact that it does not work between 8 poles and 4 poles, which have different numbers of poles. In this way, the stator and rotor, which serve both as a magnetic circuit and windings, serve not only as the main body of the synchronous machine but also as an exciter.

れうる。In FIG. 3, the connections of the three-phase rotor windings 44 are in the form of a double star. Windings 45, 46 and 47 are arranged to form one star-connected winding, and the other windings 48, 49 and 50
Assume that the windings of the other star-shaped connections are in the desired arrangement. Also windings 45 and 48, 46 and 49 and 47 and 50
and have the same phase. The intermediate terminal 36 is the neutral point terminal of the 45-46-47 windings that are to be connected in a star shape on one side, and the intermediate terminal 37 is the terminal that is the neutral point of the 45-46-47 windings that are to be connected in a star shape on the other side.
This terminal is the neutral point of the 8-49-50 winding. However, in FIG. 3, windings 46 and 49 for one phase of the three-phase winding forming a double star connection are connected to opposite neutral points 37 and 36.
Connect to. The dotted lines and X marks in the figure indicate that they are not connected. The dotted arrows shown along rotor winding 44 in FIG. It shows the direction of electromotive force or current flowed by it. On the other hand, rotor winding 44
The solid arrows shown along indicate the direction of the direct current flowing into the windings from the output terminals 27, 28 of the forward converter 20 through the intermediate terminals 36, 37 of the windings. This DC power is supplied through the forward converter 20 by the power of the voltage induced in the rotor winding 44 in the direction of the dotted arrow. The relationship between the number of magnetic poles created by the current indicated by the dotted arrow and the number of magnetic poles created by the current indicated by the solid arrow is 1:2 or 2:1, as shown in FIG. 2. For example, if one of them has 4 poles, the other has 8 poles, and the stator winding 13 in FIG. 1 and the rotor winding 4 in FIG.
It can be easily seen that the action between the stator winding 13 of FIG. 1 and the rotor winding 43 of FIG. 2 is similar to that between the stator winding 13 of FIG.

に配列した回転電気機械の構造In the stator armature windings arranged to have one star connection in the first set of three-phase windings and another star connection in the second set of three-phase windings, The connections between the windings of one phase in each of the three phases to form the first and second three-phase star-shaped connected windings and the neutral point of each of the star shapes of the two sets are reversely connected to each other. The main terminal connection circuit of the stator armature winding is electrically connected to the AC side terminal of the forward converter consisting of a rectifier so that excitation power can be supplied from the main terminal connection circuit of the stator armature winding, and the DC side terminal of the forward converter consisting of a rectifier is A structure of a rotating electric machine arranged so that direct current flows through the stator armature winding by connecting the side terminals to the two neutral points.
