ータリトランス。[Scope of Claim for Utility Model Registration] (1) A rotating side magnetic core and a fixed side magnetic core each having the same number of winding channels of multiple channels and concentric winding grooves for embedding these windings, respectively. In the rotary transformer, grooves are formed concentrically from the back side between the adjacent winding grooves on both the rotating side magnetic core and the stationary side magnetic core, so that the rotating side magnetic core and the stationary side magnetic core are A rotary transformer characterized in that each pair of windings of a magnetic core is configured to form a substantially independent magnetic circuit. (2) The rotary transformer according to claim 1, wherein the concentric grooves are filled with a non-magnetic material. (3) The rotary transformer according to claim 1, wherein the bottom surface of the concentric groove is formed to be as deep as or deeper than the bottom surface of the winding groove. (4) Utility model registration in which each magnetic core is completely magnetically separated from each winding by forming a circular groove penetrating from the back side to the opposing surface on the opposite side. A rotary transformer according to claim 2.
