<p>PURPOSE:To improve the efficiency of attaching a plurality of short rings to a cylindrical core on the inner and outer sides of a cylindrical rotary transformer. CONSTITUTION:A sheet-like short ring material 10a, in which a plurality of band-like conductors 11a to 11c are arranged in parallel and respective conductors are connected with connecting wires 12a to 12c, are used as a short ring material for forming a plurality of short rings on the inner side or outer side of a cylindrical rotary transformer. To attach a short ring on the inner side thereof, the sheet-like short ring material is wound around a cylindrical core so that the band-like conductors may be fitted into the groove on the outer surface of the cylindrical core, and the both ends of the respective band- like conductors are connected with each other. To attach a short ring on the outer side thereof, the both ends of the respective band-like conductors made of sheet-like short ring material are connected with each other so as to form a cylindrical body, and then it is fitted into the groove on the inner surface of the cylindrical core.</p> |
