Definitions

  • This implementation is delicate because the good behavior of the resin on the mechanical and dielectric level depends essentially on the precision of its composition, on the temperature at which it is poured into the casing, and on the time necessary for its hardening.
  • the terminal 16 includes, extending the rod 16 is advantageously made conductive wire, an external pad or end piece 16 b forming a male element in relief on the outside of the coil when completed.
  • thermoplastic material such as polybutyleneterephthalate (PBTB) which has good qualities of thermal conduction promoting the evacuation of calories.
  • the fundamental advantage of impregnating varnish is to create an adhesion interface between the thermoplastic material (PTO) of the insulating support 11 and the insulating enamel of the winding wire 12, on the one hand, and the thermoplastic material PBT d coating 30, on the other hand.
  • PTO thermoplastic material
  • thermoplastic coating material which adheres along the walls of the isolation compartments 28, fills said compartments to constitute baffles at the creepage distances and to increase their paths.
  • the coating material 28 may be analogous or the same as that used for coating 30 of the secondary assembly B.
  • the polybutyleneterephthalate (PBTB) used such as a thermoplastic polyester based on polytetramithylene terephthalate resin, loaded or not, gives good results because of its coefficient of expansion which accepts the deformations of the magnetic circuit during its heating in intense operation.
  • thermoplastic of the secondary assembly B and the coating of all of the elements A, B and C together can be advantageously obtained in the same molding operation.
