In order to compute the correct current distribution in the windings it was necessary to take into account all the three phases and the filter circuit (coupling a complex circuit with FEM).

The loss calculation has taken into account (for each harmonic current):

• Uneven current sharing

  • among the double disks in parallel

  • among mechanical conductors in parallel inside each disk.

• Uneven current density distribution inside each conductor because of eddy currents.
