In addition to the space reserved for its location, the supply winding is essentially characterized by the fill factor, the number of turns and the current flowing through it.

The filling coefficient K_r is the ratio between the volume of copper V_Cu making up the winding and the volume occupied by the winding V_bo:$K_{\text{r}}=\frac{V_{\text{Cu}}}{V_{\text{bo}}}$

This coefficient depends on the wire diameter. The choice of conductor diameter must be compatible with the supply current and meet energy dissipation...
