Hello dear all,
To simplify double star machines modeling, the SVD is used to transform the double star winding into a simplified two two-phase sub-machines in the dq,xy,z0z1 subspace :
https://ieeexplore.ieee.org/stamp/stamp.jsp?arnumber=464525
https://ieeexplore.ieee.org/stamp/stamp.jsp?arnumber=372577
In this subspace, the three plans are perpendicular to each other, and each plan is defined by two perpendicular vectors. All the vectors that define the plans are perpendicular to each other.
This concept can not be represented in a three dimensional space, but needs a six dimension space. But i want to make a representative schematic to simplify the understanding of this concepts to the readers, so I created the one in attached, which is somewhat imprecise.
Has anyone any idea to correct this scheme and make it more precise?
Thanks in advance for any help
