Hi Dario,
Yes, you are correct that setting the 'winding type' to 'open end' does obtain 6 electrical ports, but these electrical ports listed (a1, b1, c1, a2, b2, c2) correspond to a three-phase motor configuration with separate connections for the positive and negative ends of each phase. Thus, setting the winding to open end would still model a three-phase motor configuration.
Also, about handling the neutral point, you need to enable this port by setting the “modelling option” parameter to either of the following:
- 2-D partial derivative data | No thermal port, 2-D partial derivative data | Show thermal port, 3-D partial derivative data | No thermal port, 3-D partial derivative data | Show thermal port, 4-D partial derivative data | No thermal port, or 4-D partial derivative data | Show thermal port and set the Winding type parameter to Wye-wound.
- 3-D flux linkage data | No thermal port or 3-D flux linkage data | Show thermal port and set the Winding type parameter to Wye-wound and the Expose neutral port parameter to Yes.

I hope this helps!
