摘要： A common-mode choke coil includes a core having a winding core portion, a first winding and a second winding. A winding start side region ranges from one end portion to a position where a first winding is brought into contact with the winding core portion, and a winding finish side region ranges from the other end portion to a position where a second winding is brought into contact with the winding core portion. The first winding is wound on the winding core portion such that the first winding is positioned on a negative direction side in an x axis direction with respect to the second winding at the same turn in the winding start side region and the second winding is interposed between the first winding and the winding core portion in the winding finish side region.

摘要： A coil device includes a core and a coil portion. The core includes a winding core part and a flange part disposed at one end of the winding core part in an axial direction thereof. The coil portion is formed by winding a first wire and a second wire around the winding core part. The flange part includes first and second grooves passed by a leading part of the first wire or the second wire. The first groove extends toward an outside of the flange part. The second groove extends toward the outside of the flange part at an angle differing from that of the first groove.

摘要： Disclosed herein is a pulse transformer that includes: a drum core including a winding core part and first and second flange parts provided at both ends of the winding core part in an axial direction; a plurality of wires wound around the winding core part; and a plate-like core fixed to the drum core so as to face a first surface of the first flange part that is parallel to the axial direction and a second surface of the second flange part that is parallel to the axial direction. A value of S1/S2 is 0.19 or more and 0.47 or less, where an area of the cross section of the winding core part that is perpendicular to the axial direction is S1 and a facing area between the plate-like core and the first or second surface is S2.

摘要： A winding apparatus includes a first rotation body, and a wire position support, inserted in an insertion hole outside a center axis of the first rotation body, and including first and second wire route holes in which first and second wires are inserted, respectively. The winding apparatus further includes a second rotation body having a center axis and separated from the first rotation body, a shaft body outside the center axis, a synchronous rotation component coupling the wire position support and the shaft body while unrotatably fixed to the wire position support, a winding driver that synchronously rotates the first and second rotation bodies, and inner bearings disposed between the wire position support in the insertion hole and the first rotation body, in which the wire position support is journaled with respect to the first rotation body. Thus, the wire position support revolves orbitally about a core without rotating.

摘要： A bifilar winding system for the manufacture of poloidal field superconducting magnets for nuclear fusion includes two superconducting coil winding production lines which are symmetrically arranged, a dropping fixture, a rotary platform and a winding mold, and an automatic control system. Each of the two winding production lines includes a conductor unwinding device, a straightener, an ultrasonic cleaning machine, a sandblasting and cleaning machine, a bending machine, an inter-turn insulation taping machine. During the winding of a coil, a superconducting conductor is unwound by the conductor unwinding device under the control of the automatic control system, then straightened, ultrasonically cleaned, sandblasted and cleaned, and bent into a desired radius, then wrapped with multiple layers of insulating tape by the inter-turn insulation taping machine, and finally fixed, by the dropping fixture, precisely on the rotary platform at a correct position within a profile of the winding mold.
