Definitions

  • the present invention relates to a wound magnetic circuit and a method of manufacture of such a circuit.
  • Wound magnetic circuits are used in many fields among which are current sensors and transformers. In applications such as current sensors, accuracy is closely related to the magnetic properties of the materials used and the precision of manufacturing. Achieving desired precision is often against the need reduce the manufacturing cost and reduce the size of the components.
  • the angle ⁇ of the cone can be very small and have, for example, a value tan ⁇ between 0.001 and 0.01. The difference in coil diameter between the ends is thus negligible.
