Now we have to choose a standardized bare wire diameter from Table 15.3.
The value of 1.15 mm is standardized, so each coil is made of 15 turns and each turn contains
2 elementary conductors in parallel (diameter dCo’ = 1.15 mm).
If the number of conductors in parallel ap > 4, the number of current paths in parallel has to be
increased. If, even in this case, a solution is not found, use is made of rectangular cross section
