Changing Winding Direction (Terminals)

Changing Winding Direction Using Terminals

 

  1. Introduction
    • An example is taken from a three-limb inductor.
    • Switched to a two-limb core for simplicity.
  2. Setting up Windings
    • Copied one winding and applied a translation for the second winding.
    • Positioned the windings on separate limbs that cross the y-axis.
  3. Assembly
    • Created an assembly with a gapped core and two windings.
  4. Electromagnetics Configuration
    • Ensure both windings are selected as primary.
    • Connect the coil group in series to allow current flow through both windings.
  5. Defining Current Direction
    • Specify positive and negative terminals to indicate the current direction.
    • Currents can be set to flow in opposite directions by terminal configuration.
  6. Circuit Configuration
    • No changes are needed as both windings correspond to one femcoil group.
  7. Simulation Setup
    • Set up a harmonic simulation with the fundamental frequency.
    • Disable heat and mesh the case before solving.
  8. Analyzing Results
    • Run the simulation to obtain results.
    • Losses for primary winding correspond to both windings.
    • Newer versions show DC resistances, AC resistances, and more for each coil separately.
  9. Conclusion
    • Magnetic flux is oriented in the same direction, indicating no Flux Cancellation.
    • Both windings have currents flowing in opposite directions, ensuring correct operation.
