Nexperia’s app note for multiphase machines. Link here (PDF)
This application note describes the advantages of multiphase machines and prompts the reader to their recent, widely expanded usage. A short description of the power MOSFET switch design in is given, relying heavily on the more descriptive design. A short description of the control method for multiphase PMSMs is given with emphasis on the difference between threephase and multiphase machine control. The differences in the control method lays mostly in the transformation matrices.
