3. 2. 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.

4. 3. 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

5. 4. Electromagnetic Sizing of Axial-Flux Induction Machines and Experimental Validation

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

   Author : Leonardo Colombo; [2021]
   Keywords : Sizing algorithm; Double-stator axial-flux machines; Finite-element method; Material identification.; Dimensioneringsalgoritm; Dubbel statoriska axiella flödesinduktionsmaskiner; Finita-element metoden; Material-identifieringsprocedurer;

   Abstract : With a rising drive towards greener means of transportation, electrical machines for propulsion are becoming a scientific field of major interest. In particular, part of the research studying these devices focuses its efforts on axial-flux machines, which compared to radial-flux machines can offer a better length-to-diameter ratio and higher torque arm for similar ratings.
