<P>PROBLEM TO BE SOLVED: To increase bond strength between an insulation paper and an insulation tube. <P>SOLUTION: An insulation paper 51 has tongue potions 51b1 and 51b2 on its cylindrical part 51b. An insulation paper 52 also has tongue portions 52b1 and 52b2 on its cylindrical part 52b. When the cylindrical part 51b of the insulation paper 51 is fitted into a stepped peripheral surface 53-1 of an insulation tube 53, the tongue portions 51b1 and 51b2 ride on the outer peripheral surface 53-3 of the insulation tube 53. When the cylindrical part 52b of the insulation paper 52 is fitted into a stepped peripheral surface 53-2 of the insulation tube 53, the tongue portions 52b1 and 52b2 ride on the outer peripheral surface 53-3 of the insulation tube 53. The tongue portions 51b1, 51b2, 52b1 and 52b2 that ride on the surface are strongly fastened to the outer peripheral surface 53-3 of the insulation tube 53 by winding of an excitation coil 6 and provide increased bond strength. <P>COPYRIGHT: (C)2012,JPO&INPIT |
