  1. 1. 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.

  2. 2. 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

  3. 3. 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.

  4. 4. Torque Ripple Analysis and Compensation of Servo Drives for Robot Application

    University essay from Lunds universitet/Industriell elektroteknik och automation

    Author : August Millqvist; [2021]
    Keywords : Technology and Engineering;

    Abstract : Permanent magnet synchronous motors or PMSMs are commonly used in multiple applications, both in industry and commercial use. These motors have many pros when compared to other electrical machines but do present the issue of torque ripple, especially cogging torque. READ MORE

  5. 5. Hybrid Vehicle Control Benchmark

    University essay from Linköpings universitet/Fordonssystem

    Author : Ruchit Anilbhai Bhikadiya; [2020]
    Keywords : Hybrid electric vehicle; Dynamic Programming; Powertrain Modes;

    Abstract : The new emission regulations for new trucks was made to decrease the CO2 emissions by 30% from 2020 to 2030. One of the solutions is hybridizing the truck powertrain with 48V or 600V that can recover brake energy with electrical machines and batteries. The control of this hybrid powertrain is key to increase fuel efficiency. READ MORE
