1. 21. 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. 22. Markov Chain Monte Carlo (MCMC) and Bayesian Inference for Gravitational Waves

   University essay from Lunds universitet/Astronomi - Genomgår omorganisation

   Author : Christine Andersson; [2021]
   Keywords : Gravitational Waves; LISA; LISA mission; Bayesian Inference; Markov Chain Monte Carlo; MCMC; Bayes’ Theorem; stochastic sampling; Metropolis Hastings; histograms; Physics and Astronomy;

   Abstract : The Laser Interferometer Space Antenna (LISA) is a space borne gravitational wave detec- tor set to launch in 2034, with the objective of detecting and studying the Gravitational Waves (GWs) of our universe. So far, ground-based detectors such as the Laser Interferometer Gravitational-Wave Observatory (LIGO) have been successful in detecting GWs, but the limitations of ground based detectors is what makes LISA so special.

4. 23. Online Parameter Estimation of a Six- Phase Machine for Marine Application

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

   Author : Raimundo Montalba Mesa; [2021]
   Keywords : Multiphase electrical machines; IPSM; Parameter estimation; Online estimation; Stator resistance estimation; Permanent magnet flux estimation.; Flerfas elektriska maskiner; IPSM; Parameteruppskattning; Online uppskattning; Statorresistans uppskattning; Flödesuppskattning av permanentmagneter.;

   Abstract : In the recent decades, an increased interest into multiphase machines has developed due to certain beneficial properties they have over the standard three- phase machines. Proper modelling of a multiphase machine allows access to higher degrees of freedom given by the ability to control higher order harmonic frames. READ MORE

5. 24. Modelling and design of PMSM position drivesusing model following control

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

   Author : JACOB RÖING; CARL JENSEN; [2021]
   Keywords : ;

   Abstract : Teenage Engineering is a Swedish electronics company that want to automate their quality control process. For this purpose, they want to develop a test jig that can perform tactile testing of their products. The test jig will utilize PMSM motors for position control of the end-effector. READ MORE

6. 25. 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
