Six phase PMSM FEM pamarametrized model block

Hello, I would like to know if it is possible to use the simscape electrical ‘FEM-Parameterized PMSM’ block to model a six phase PMSM using flux data and loss map. In particular, I saw that it is possible to set ‘winding type -> open end’ to obtain 6 electrical ports to the block. Do these ports actually represent the 6 distinct phases? If so, how should I handle the neutral points?

Here is a picture of the block in question

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:

1. 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.
2. 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!
