板状ロータコアの対向面にそれぞれ環状溝を形成
し、該環状溝に巻線を嵌装したロータリ変成器に
おいて、前記両コアによつて形成される磁路中の
ステータコア及びロータコアの対向面にそれぞれ
凹部及び凸部を形成し、該凹部及び凸部によつて
形成される間隙に磁性流体を介在させたことを特
徴とするロータリ変成器。 In a rotary transformer in which an annular groove is formed on the opposing surfaces of a disc-shaped stator core and a disc-shaped rotor core that face each other with a gap in between, and a winding is fitted in the annular groove, the rotary transformer is formed by the two cores. A rotary transformer characterized in that a concave portion and a convex portion are formed on opposing surfaces of a stator core and a rotor core in a magnetic path, respectively, and a magnetic fluid is interposed in a gap formed by the concave portion and the convex portion.
