Abstract

1517683 Transformers INTERNATIONAL BUSINESS MACHINES CORP 24 Jan 1977 [25 Feb 1976] 02826/77 Heading HIT [Also in Division G5] A rotary transformer has an annular airgap between two radially separated relatively rotatable parts, each having a respective core element 27, 31, Fig. 2 of interrupted annular form, surrounded by a coil. The core elements may be formed by cutting respective pairs of annular grooves 34, 36 and 62, 64 in the adjacent surfaces of the parts, each pair being connected by a respective through slot 42, 66 through which the respective ends of the windings 28, 32 may be passed. A printed circuit winding may be used, Fig. 7A which may be centre tapped, Fig. 7B having an aperture 104 to accommodate the core element, and terminal pads 98. The core may be ferrite and the windings conventional wire conductors. The transformer may be used in a helical wrap, rotary head magnetic tape recorder/reader.
