1. Sensorless Control of Synchronous Machines in Python Using Signal Injection : An implementation of a High-Frequency Square-Wave Injection Algorithm on a Linear and Non-Linear Synchronous Machine Model in open-source Software Motulator
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : The importance of accurately controlling the speed and torque of Synchronous Machines (SMs) in industry, transportation, aerospace, to name a few, can not be overstated. The driving unit to control the machines are called Variable Speed Drives (VSDs) and they can be designed in many different ways. LÄS MER
2. Concept Population & Verification of Traction Motors
Master-uppsats, KTH/FordonsdynamikSammanfattning : The electrification of automobiles has emerged as the sustainable powertrain solutionto meet United Nations sustainable development goals of sustainable cities andcommunities, affordable and clean energy, and climate action. The success of theelectrification depends on the efficiency of traction motors. LÄS MER
3. CURRENT OVERSAMPLING ANALYSIS FOR ADVANCED CONTROL OF ELECTRIC AC DRIVES
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : The main purpose of this thesis is to develop a sensorless control for a synchronous reluctance motor by using the slope measurement of the current ripple introduced by the Space Vector Modulation.The position estimation is performed at each Space Vector Pulse Width Modulation period and it relies on the estimation of current derivatives.

4. Utvärdering av roterande borstlösfrekvensomformare tillspårledningar
M1-uppsats, KTH/Hälsoinformatik och logistikSammanfattning : Spårledningar används inom tunnelbanan för att visa tågets position samt bestämma tågets hastighet genom att bryta spänningsamplituden i signalen vid olika frekvenser. Frekvensen till spårledningen fås från en roterande frekvensomformare. I dagens anläggning används roterande frekvensomformare med borstar. LÄS MER
5. Design and Analysis of a Fractional-Slot Concentrated-Wound PM-Assisted Reluctance Motor
Uppsats för yrkesexamina på avancerad nivå, KTH/Elektrisk energiomvandlingSammanfattning : The aim of this master thesis is to design and analyse a FSCW PMaSynRM (Permanent Magnet assisted Synchronous Reluctance Motor) for industrial applications. The design process includes analytical calculations (initial design and PM amount minimization) and nite element method (FEM) based design optimization. LÄS MER
