1. 11. Commissioning of a FPGA/DSP unit for Centralized Control of a Variable Phase Pole Multiphase Machine

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Jonas Hansson; [2022]
   Keywords : Harmonic Plane Decomposition; Multiphase Electrical Machine; Wound Independently-Controlled Stator Coils; System on a chip; Control Implementation; Hardware Design ; Motorstyrning; Asynkronmotor; Multifasmaskin; Programmering; Systemkrets; Hårdvarukonstruktion;

   Abstract : 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.

   Abstract : Insulation in rotating machines is a common cause for failure. Therefore, research in the area is large and is important to further increase the knowledge of the phenomena related to insulation degradation. READ MORE

6. 15. Development of an experimental six-phase induction machine drive

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Adam Bianchi; [2021]
   Keywords : Asymmetrical six-phase induction machine; indirect rotor field oriented control; machine rewinding; multiphase electrical machines; PCB design; speed control; the star of the slot .; Asymmetrisk sexfasig asynkronmaskin; flerfasiga elektriska maskiner; hastighetsreglering; indirekt rotorfälts orienterad reglering; kretskorts design; maskinomlindning; the star of the slot .;

   Abstract : 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. READ MORE
