<p><P>PROBLEM TO BE SOLVED: To provide a rotary transformer in which power transmission efficiency is improved as much as possible. <P>SOLUTION: An annular iron core 12 is divided into a primary iron core 13 and a secondary iron core 14 over the whole periphery of the iron core 12 through a gap 15, and a primary winding 17 and a secondary winding 18 are formed so as to be united with the primary iron core 13 and the secondary iron core 14, respectively. The primary winding 17 is divided into a plurality of windings 17a, 17b and 17c to form cylindrical formed objects 19a, 19b and 19c, the secondary winding 18 is divided into a plurality of windings 18a, 18b and 18c to form cylindrical formed objects 20a, 20b and 20c, and these primary-side and secondary-side formed objects 19a, 19b, 19c and 20a, 20b, 20c are arranged concentrically and alternately in the diameter direction. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
