Abstract

PURPOSE:To enable to reduce the electromagnetic repulsive force generating between each set of windings by a method wherein a magnetic substance is arranged between each set of windings, and the greater part of magnetic flux generating on the windings of each set is flowed to the magnetic substance. CONSTITUTION:A magnetic substance 8 is arranged between each set of windings 1 and 2 and windings 3 and 4 which are juxtaposed in axial direction of a core 5. As a result, the greater part of the magnetic flux generated on the windings 1 and 2 and the windings 3 and 4 flows on the magnetic substance 8 even when a reverse-directioned current runs between the sets of windings 1 and 2 and windings 3 and 4. As the magnetic flux which interlinks the windings 1 and 2 and the windings 3 and 4 is reduced, and the electromagnetic repulsive force generating between the sets of windings 1 and 2 and windings 3 and 4 is also reduced.

Description

[Detailed description of the invention] [Field of application of the invention] The present invention relates to an inductive flow divider for a vehicle.

[Background of the invention]

An inductive shunt for a vehicle is used to adjust the current flowing to the main pole of a motor for a vehicle, and a conventional example of this type of inductive shunt for a vehicle is shown in FIG.

As shown in the figure, the inductive shunt for a vehicle has an even number of windings 1, 2, 3.4 arranged in parallel, and these windings 1, 2, 3.
3.4, and an iron core 5 that forms a magnetic path, and windings 1, 2, and 3.4 arranged in parallel with this iron core 5.
It is composed of iron plates 6 and 7 that are attached to the ends of the magnetic field and form a magnetic path. The windings 1, 2, and 3.4 are electrically connected into two sets of windings 1.2 and 3.4,
Current flows in the same direction through each winding 1.2, 3.4. Since the current is flowing in the same direction in this way, as shown in Figure 2, the distance between the windings 1, 2 and 3.4 of each set is determined by the ttK and the lines of magnetic force shown in the figure. The electromagnetic force generated is an attractive electromagnetic force that is attracted by Fleming's left-hand rule. In addition, × in the figure
The mark indicates the direction of the current flowing from the front to the back of the paper.

By the way, in the event of an accident or an electrical connection error in a vehicle induction shunt configured in this way, the winding 1,
2, 3, and 4, currents may flow in opposite directions as shown in FIG.

Note that the marks in the figure indicate the direction of the current flowing from the back of the page to the front of the paper. When the current flows in the opposite direction in this way, as shown in Figure 4, there is a gap between windings 1.2 and 3.4 of each wire, as indicated by the arrow in the figure, due to Fleming's left hand rule. There was a concern that this would cause electromagnetic repulsion and damage the inductive shunt for vehicles.

[Purpose of the invention]

The present invention has been made in view of the above points, and provides an induction vehicle for vehicles that makes it possible to reduce the electromagnetic repulsion force generated between the windings of each wire even if a current flows in the opposite direction between the windings of each wire. The purpose is to provide a flow divider.

[Summary of the invention]

That is, the present invention includes an iron core, an even number of windings arranged in parallel in the axial direction or radial direction of the iron core, and supporting the ends of the arranged windings, and supporting the ends of the windings in the axial direction of the iron core. In an inductive shunt for a vehicle, the windings are electrically connected in at least two or more sets, and a magnetic material is disposed between the windings of each wire. %
As a result, even if current flows in the opposite direction between the windings of each wire, most of the magnetic flux generated in the windings of each wire will flow through the magnetic material.

[Embodiments of the invention]

The present invention will be explained below based on the illustrated embodiments. An embodiment of the invention is shown in FIGS. 5 and 6. Note that parts that are the same as those in the conventional system are given the same reference numerals, and therefore their explanations will be omitted. In this embodiment, a magnetic body 8 is disposed between the windings 1, 2 and 3°4 of each wire arranged in parallel in the axial direction of the iron core 5. By doing this, windings 1, 2 and 3, 4 for each wire
Even if a current flows in the opposite direction between them, most of the magnetic flux generated in the windings 1, 2 and 3, 4 flows through the magnetic body 8 and interlinks with the windings 1, 2, 3, 4. As the magnetic flux decreases, even if a current flows in the opposite direction between windings 1, 2 and 3.4 of each wire, it will occur between windings 1°2 and 3.4 of each wire. An inductive shunt f for a vehicle capable of reducing electromagnetic repulsion can be obtained.

In other words, since the magnetic body 8 is arranged between the windings 1, 2 and 3, 4 of each wire, even if a current flows in the opposite direction between the windings 1, 2 and 3, 4 of each wire, Most of the magnetic flux generated in the windings 1.degree.2 and 3.4 flows through the magnetic body 8, respectively.

When much of the magnetic material 8 flows in this way, the magnetic flux interlinking with the windings 1, 2, and 3.4, that is, the magnetic flux density, decreases. Let the current flowing in .2 and 3.4 be i, and the length of the current flow be t, then the electromagnetic force F is F=Bxtx
t, the magnetic flux density B becomes smaller and the magnetic force F becomes smaller. The repulsive force can be reduced, and damage to the vehicle induction shunt can be prevented.

In this embodiment, windings 1 to 4 are arranged in order in the axial direction of the iron core 5.

, 4 flows through the magnetic bodies 8, 9, and 10, respectively, and the magnetic flux density interlinking with the windings 1, 3, and 2° 4 of each wire decreases. It is possible to achieve the same effects as in the case of .

FIG. 8 shows yet another embodiment of the invention. In this embodiment, an even number of windings 1 and 2 are arranged in parallel in the radial direction of the iron core 5'lr, and the windings 1 and 2 are electrically connected separately. A magnetic body 8 was placed between the two. In this case, even if a direct current flows in the opposite direction between the windings 1 and 2, which are the windings for each wire, most of the magnetic flux flows into the magnetic body 8, resulting in the same effect as in the previous case. It can be effective.

FIG. 9 shows yet another embodiment of the invention. In this embodiment, windings 1.
2 and winding 3.4 are placed side by side, and these windings 1 and 2 are
and 3 and 4 are arranged in parallel in the axial direction, and among these windings 1 to 4, windings 1.4 and 2.3 are electrically connected as a set, and the winding between each winding is A magnetic body 8 was disposed between the wires 1, 2 and 3°4, a magnetic body 9 was disposed between the windings 1 and 2, and a magnetic body 1o was disposed between the windings 3 and 4.

Even in this case, even if current flows in the opposite direction between windings 1, 4 and 2 of each wire, windings 1, 4 and 2 of each wire,
Most of the magnetic flux generated in 3 flows through the magnetic bodies 8, 9, and 10, respectively, and the same effects as in the case described above can be achieved.

FIG. 10 shows yet another embodiment of the invention.

In this embodiment, windings 1, 2,
3.4, when the windings 1.4 at both ends and the middle windings 2 and 3 are electrically connected as a set, there is a magnetic material 8 between the windings 1 and 2 between the windings of each wire. A magnetic body 9 was disposed between the windings 3 and 4. Even in this case, even if current flows in the opposite direction between the windings 1, 4 and 2, 3 of each wire, most of the magnetic flux generated in the windings 1, 4 and 2, 3 of each wire is generated by the magnetic material 8. , 9, and the same effects as in the above case can be achieved.

Although the present embodiment has been described with reference to the case where two or four windings are used, the same method can be applied to the case where more windings are used.

Although there are examples in which this type of magnetic material is provided in a transformer to reduce induction disturbances or generated losses in the transformer, the purpose is different from that of this embodiment.
