Abstract
A core main body includes: an outer peripheral iron core, and at least three iron cores coupled to an inner surface of the outer peripheral iron core, in which a gap is formed between adjacent iron cores among the at least three iron cores, the gap being magnetically connectable, and a plurality of notches are formed on an outer circumferential surface of the outer peripheral iron core, the plurality of notches extending in an axial direction of the outer peripheral iron core. The reactor includes such a core body.

A reactor comprising:
- a core main body, wherein
- the core main body including
- an outer peripheral iron core, and
- at least three iron cores and coils coupled to an inner surface of the outer peripheral iron core,
- the at least three iron core coils including at least three iron cores and coils respectively wound around the iron cores,
- the at least three iron cores respectively having radial inner end portions positioned near a center of the outer peripheral iron core, converging toward the center of the outer peripheral iron core,
- a gap being formed between one iron core of the at least three iron cores and another iron core adjacent to the one iron core, the gap being magnetically connectable,
- the radial inner end portions of the at least three iron cores being spaced apart from each other with the gap being magnetically connectable,
- a plurality of notches being formed on an outer circumferential surface of the outer peripheral iron core, the plurality of notches extending in an axial direction of the outer peripheral iron core,
- the reactor further comprising:
- two iron core anchoring parts respectively arranged on both end faces of the outer peripheral iron core;
- and
- a plurality of bolts passing through the plurality of notches and configured to anchor the core main body by sandwiching between the two iron core anchoring parts.
A core main body comprising:
- an outer peripheral iron core, and
- at least three iron cores coupled to an inner surface of the outer peripheral iron core, wherein
- the at least three iron cores respectively have radial inner end portions positioned near a center of the outer peripheral iron core, converging toward the center of the outer peripheral iron core,
- a gap is formed between one iron core of the at least three iron cores and another iron core adjacent to the one iron core, the gap being magnetically connectable, the radial inner end portions of the at least three iron cores are spaced apart, from each other with the gap being magnetically connectable, and
- a plurality of notches are formed on an outer circumferential surface of the outer peripheral iron core, the plurality of notches extending in an axial direction of the outer peripheral iron core.
A manufacturing method for a reactor, the manufacturing method comprising steps of:
- preparing a core main body, wherein
- the core main body including
- an outer peripheral iron core, and
- at least three iron cores and coils coupled to an inner surface of the outer peripheral iron core,
- the at least three iron core coils including at least three iron cores and coils respectively wound around the iron cores,
- the at least three iron cores respectively having radial inner end portions positioned near a center of the outer peripheral iron core, converging toward the center of the outer peripheral iron core,
- a gap being formed between one iron core of the at least three iron cores and another iron core adjacent to the one iron core, the gap being magnetically connectable,
- the radial inner end portions of the at least three iron cores being spaced apart from each other with the gap being magnetically connectable,
- a plurality of notches being formed on an outer circumferential surface of the outer peripheral iron core, the plurality of notches extending in an axial direction of the outer peripheral iron core,
- the manufacturing method for the reactor further comprising steps of:
- arranging two iron core anchoring parts on both end faces of the outer peripheral iron core, respectively;
- and
- causing a plurality of bolts to pass through the plurality of notches and anchoring the core main body by sandwiching between the two iron core anchoring parts.
