1. Theoretical Magnet Design : From the electronic structure of solid matter to new permanent magnets
Sammanfattning : A good permanent magnet should possess a large saturation magnetisation (Ms), large mag- netocrystalline anisotropy energy (MAE) and a high Curie temperature (TC). A difficult but important challenge to overcome for a sustainable permanent magnet industry is to find novel magnetic materials, exhibiting a large MAE, without the use of scarcely available elements such as rare-earth metals.

2. Wave Energy Conversion : Linear Synchronous Permanent Magnet Generator
Sammanfattning : This thesis studies the electric aspects of a linear synchronous permanent magnet generator. The generator is designed for use in a wave energy converter, which determines the fundamental requirements of the generator. The electromagnetic properties of the generator are investigated with a finite element based simulation tool. LÄS MER
3. Design of a Permanent-Magnet Assisted Synchronous Reluctance Machine for a Plug-In Hybrid Electric Vehicle
Sammanfattning : .... LÄS MER
4. 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
5. Demagnetization and Fault Simulations of Permanent Magnet Generators
Sammanfattning : Permanent magnets are today widely used in electrical machines of all sorts. With their increase in popularity, the amount of research has increased as well. In the wind power project at Uppsala University permanent magnet synchronous generators have been studied for over a decade. LÄS MER
