Abstract
(EN)
A coil device 20 that comprises: a core 30 that is a magnetic body that has a pair of facing walls 32A, 32B that are arranged so as to face and a plurality of leg parts 40 that protrude toward the sides toward which the facing walls 32A, 32B face at different areas of the facing walls 32A, 32B; and a plurality of windings 21 that are wound on the plurality of leg parts 40. In an area that is between the adjacent plurality of windings 21, the facing walls 32A, 32B of the coil device 20 comprise a reduced-diameter part 38 at which the cross-sectional area of the facing walls 32A, 32B in a cross-section that is orthogonal to the direction of the magnetic flux ϕ1 that is generated inside the facing walls 32A, 32B as a result of energization of the windings 21 is smaller.

La présente invention concerne un dispositif de bobine 20 qui comprend : un noyau 30 qui est un corps magnétique comprenant une paire de parois opposées 32A, 32B qui sont agencées de manière à se faire face et une pluralité de parties de patte 40 qui font saillie vers les côtés vers lesquels les parois opposées 32A, 32B se font face au niveau de différentes zones des parois opposées 32A, 32B; et une pluralité d'enroulements qui sont enroulés sur la pluralité de parties de patte 40. Dans une zone qui se trouve entre la pluralité adjacente d'enroulements 21, les parois opposées 32A, 32B du dispositif de bobine 20 comprennent une partie à diamètre réduit 38 au niveau de laquelle la section transversale des parois opposées 32A, 32B dans une section transversale qui est orthogonale à la direction du flux magnétique ϕ1 qui est généré à l'intérieur des parois opposées 32A, 32B suite à l'excitation des enroulements 21 est plus petite.
