1. 1. 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. 2. Field Oriented Current Control with Harmonic Injection in a Six-Phase Induction Machine

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

   Author : Xinyue Shan; [2021]
   Keywords : Multi-phase machine; asymmetrical six-phase induction machine; harmonic plane decomposition; indirect rotor field oriented control; parameter estimation; Flerfasmaskin; asymmetrisk sexfasinduktionsmaskin; harmonisk plan sönderdelning; indirekt rotorfältorienterad styrning; parameteruppskattning;

   Abstract : As a new type of machine, the multi-phase machine has the advantages ofhigher power rating, higher fault tolerance capability and more degrees offreedom to control compared with the traditional machine. Aiming at runninga multi-phase machine with different phase-pole configurations smoothly,a new method called harmonic plane decomposition is presented. READ MORE

4. 3. Control Implementation and Co-simulation  of A 6-DOF TAU Haptic Device

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Yang Zhang; [2020]
   Keywords : Co-simulation; Haptic rendering; Multi-body simulation MBS ; Parallel robot; Samsimulering; Haptisk rendering; Multi-body simulation MBS ; Parallell robot;

   Abstract : In the research area of virtual reality, the term haptic rendering is defined as the process of computing and generating the interaction force between the virtual object and the operator. One of the major challenges of haptic rendering is the stably rendering contact with a stiff object. READ MORE

5. 4. Biopolitical bodies at the Greek-Turkish border

   University essay from Malmö universitet/Fakulteten för kultur och samhälle (KS)

   Author : Giorgos Litsis; [2020]
   Keywords : Biopolitics; state of exception; bare life; homo sacer; borders;

   Abstract : On 27 February 2020, Erdogan announced that he would open the Turkish border, allowing refugees to cross into Europe. Greece’s response was the deployment of military forces and the suspension of asylum applications. READ MORE

6. 5. Performance Analysis of Unskewed Asymmetrical Rotor for LV Induction Motors

   University essay from KTH/Elektrisk energiomvandling

   Author : Usman Shaukat; [2012]
   Keywords : Induction motor; skewed rotor; inter-bar currents; starting performance; asymmetrical rotor slots; 2D FEM; synchronous torques.;

   Abstract : This master thesis presents a comparative analysis of the starting performance and losses at rated operation for a 15 kW, 4-pole industrial induction motor, mounted with standard skewed, unskewed and unskewed asymmetrical die-cast aluminium rotors through measurements and simulations. It is a well-known fact that rotor skewing suppresses the synchronous torques at low speeds and also reduces the audible noise of the machine. READ MORE
