Problems solved by technology

[0004] In conventional reactors, among the three coils, the positions of the two terminals of each coil are all the same, and when the terminals of the three coils are connected to the terminal block by a relay member, there is a relay. The problem that the shape of the member is complicated
Furthermore, when the relay members intersect each other, there is a risk of a short circuit due to vibration.

Embodiment Construction

[0023] Hereinafter, a reactor according to the present invention will be described with reference to the drawings. However, it should be noted that the technical scope of the present invention is not limited to these embodiments, but extends to the inventions described in the claims and their equivalents.

[0024] Figure 1A A perspective view of the reactor 101 according to the first embodiment is shown in Figure 1B A plan view of the reactor 101 according to the first embodiment is shown in . figure 2 is a plan view of the reactor 101 according to the first embodiment, and the relay member is removed. Reactor 101 according to Embodiment 1 has outer peripheral core 1 , three leg cores 21 , 22 , 23 , and three coils 31 , 32 , 33 .

[0025] The outer peripheral core 1 may be composed of three outer peripheral core parts 11, 12, 13, that is, a first outer peripheral core part 11, a second outer peripheral core part 12, and a third outer peripheral core part 13. . The oute...

Abstract

The present invention provides a reactor. The reactor includes: an outer peripheral iron core; three leg iron cores; and three coils, each of the coils having an input side coil end and an output sidecoil end projecting from a same end surface on an end side in the axial direction of the three leg iron cores, where the three coils include two first coils in which a projecting position of the input side coil end and a projecting position of the output side coil end has a first relative positional relationship and include one second coil having a second relative positional relationship oppositeto the first relative positional relationship and where winding directions from the input side coil end to the output side coil end of the first and the second coils are reversed to each other.

Description

technical field [0001] The present invention relates to a reactor, and more particularly to a reactor having a relay member between input and output terminals. Background technique [0002] Reactors are mainly used in industrial robots and machine tools. They are installed between the power supply side (primary side) and the inverter, or between the load side (secondary side) of the motor and the inverter, and are used to prevent inverter failure. reduction and improvement of power factor. [0003] As a reactor that prevents magnetic flux from leaking to the outside, there is disclosed a three-phase reactor that includes a central core, an outer peripheral core that surrounds the central core, and a core that magnetizes the central core and the outer core to each other. At least three connecting parts for connection, the connecting part is composed of one or more connecting iron cores, one or more coils wound around the connecting iron cores, and one or more gaps (for examp...
