Changing Winding Direction Using Terminals
- Introduction
- An example is taken from a three-limb inductor.
- Switched to a two-limb core for simplicity.
- 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.
- Assembly
- Created an assembly with a gapped core and two windings.
- Electromagnetics Configuration
- Ensure both windings are selected as primary.
- Connect the coil group in series to allow current flow through both windings.
- 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.
- Circuit Configuration
- No changes are needed as both windings correspond to one femcoil group.
- Simulation Setup
- Set up a harmonic simulation with the fundamental frequency.
- Disable heat and mesh the case before solving.
- 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.
- Conclusion
- Magnetic flux is oriented in the same direction, indicating no Flux Cancellation.
- Both windings have currents flowing in opposite directions, ensuring correct operation.
