Definitions

  • Another important object of the invention is to considerably reduce the number of parts necessary to ensure the electrical insulation of the windings. This results in a reduction in the cost of raw materials, and above all a reduction in the cost of the labor required for assembly.
  • a three-layer winding a first layer 260 formed of radial turns which are contiguous in the central chimney 12 of the circuit, and which are spaced from one another on the lateral external peripheral face of the circuit; this first layer 260 is covered by a second layer 261, shown partially in Figure 9, formed of radial turns also contiguous in the central chimney 12, itself surmounted by a third layer 262 of the same structure, which covers it.
  • the same insulation technique can however be used advantageously between two successive layers of conductors of the same electrical winding, allowing on the one hand to electrically insulate the successive layers, allowing on the other hand the transfer of heat energy to the exterior, finally allowing, for certain applications, to facilitate winding by guiding the conductors.
