1. 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
2. Design of a Permanent-Magnet Assisted Synchronous Reluctance Machine for a Plug-In Hybrid Electric Vehicle
Sammanfattning : .... LÄS MER
3. 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
4. Rare Earth Metal–Free Permanent Magnet Generators
Sammanfattning : Permanent magnet (PM) synchronous generators (SGs) are used in renewable energy production. The preferred PM material is neodymium-iron-boron (NdFeB), which has very high performance and, until recently, low cost. LÄS MER
5. Synchronous Reluctance Machine (SynRM) in Variable Speed Drives (VSD) Applications
Sammanfattning : This thesis is comprehensively dedicated to the theoretical and experimental reevaluation of the Synchronous Reluctance Machine (SynRM). A simple approach to derive the SynRM main characteristics and behavior is followed. An introduction to an evaluation of the different control strategies in is given. LÄS MER
