1. Design of a Permanent-Magnet Assisted Synchronous Reluctance Machine for a Plug-In Hybrid Electric Vehicle
Sammanfattning : .... LÄS MER
2. Design of Rare Earth Free Permanent Magnet Generators
Sammanfattning : Low speed permanent magnet (PM) synchronous generators (SGs) are commonly used in renewable energy. Rare earth (RE) PMs such as neodymium-iron-boron are a popular choice due to their high performance. LÄS MER
3. Demagnetization Studies on Permanent Magnets : Comparing FEM Simulations with Experiments
Sammanfattning : In a world where money often is the main controlling factor, everything that can be tends to be more and more optimized. Regarding electrical machines, developers have always had the goal to make them better. LÄS MER
4. Control of permanent-magnet synchronous machines in automotive applications
Sammanfattning : This thesis deals with the design and analysis of control system structures for electric drives equipped with permanent-magnet synchronous machines (PMSMs) in automotive applications. Sensorless control, meaning vector control without a mechanical rotor position sensor, is considered and a speed and position estimator of phase-locked loop type is analyzed thoroughly. LÄS MER
5. Design and Evaluation of a Permanent Magnet Generator for Wave Power Applications
Sammanfattning : In this thesis, the performance of a wave energy converter (WEC) consisting of a single point absorber wave device coupled with a radial flux permanent magnet generator is investigated. The available wave power and the energy potential are studied for a specified wave climate and the electric power output is determined through an analytical buoy movement simulation. LÄS MER
