Definitions

  • FIG. 1 illustrates one coil disc section 22 of the winding 20.
  • the disc section 22 is formed by strap conductors 24 and 26 which are disposed radially adjacent to each other throughout the disc section 22.
  • the finish ends 28 and 30 of the conductors 24 and 26 are located on the outside of the disc section 22.
  • the start ends 32 and 34 of the conductors 24 and 26 are located on the inside of the disc section 22.
  • This invention relates to the arrangement of the conductors in disc sections such as section 22, and to the method of winding such sections.
  • FIG. 3 represents schematically an interleaved winding 60 having disc sections with both an even and an odd number of conductor-turns.
  • Coil disc sections 62 and 64 contain an even number of conductor-turns and coil disc sections 66 and 68 contain an odd number of conductor-turns.
  • the finish-finish connections 70, 72 and 74 are made by a continuous conductor and without any splices or joints between the disc sections.
  • the finish-finish connections 70, 72 and 74, together with the start-start connections 76, 78 and 80, provide the same type of interleaving of the conductors as exists in the winding 36 shown in FIG. 2.
  • each of said coil disc sections having a plurality of radially disposed turns of said conductors forming conductor-turns with each of said coil disc sections having an odd number of total conductor-turns
