# [Mixed A- and H- formulation for modeling electrical machines with superconducting windings](https://htsmodelling.com/model-files/a-mixed-a-and-h-formulation-approach)

The model uses the H-formulation for the superconducting windings and the A-formulation for the non-superconducting parts. Two important lines are defined: the “tramodel” lines, which separates the two formulations, and the “rotation” line, which separates the fixed and rotating parts.
