1. Turn number - see the turn of the whole phase so that our current will be very close to the desired value.
2. Calculation of wire area - why didn't you use cmil?
3. CMA of 450 is not for this size!!

Small size gets lower loss and can use with smaller CMA.

5. Flux density should be cal for both low and high speed.
