   Sammanfattning : Multiphase Electrical Machines (MPEMs) with variable phase-pole configurations have recently gained interest as it offers advantages such as a larger operating range and improved fault tolerance compared to more traditional MPEMs. The current state-of-the-art modeling and control method, Vector Space Decomposition (VSD), has the drawback of introducing discontinuities in the model when transitioning from one phase-pole configuration to another.

   Sammanfattning : Electrical machines with more than three phases are usually called multiphase electrical machines and they can have several advantages compared to conventional three-phase electrical machines such as a lower content of space-harmonics, lower torque ripple and better fault tolerance. This degree project involves rewinding of a three-phase induction machine into an asymmetrical six-phase machine. LÄS MER
