1. Analysis and control of magnetic forces in synchronous machines
Abstract : In a synchronous machine, radial, tangential, and axial forces are generated. In this thesis, three different technologies to control them are proposed. The first one, involves the utilization of the radial forces that arise between the rotor and the stator. READ MORE

2. Development of Vortex Filament Method for Aerodynamic Loads on Rotor Blades
Abstract : Wind power is currently one of the most reliable new energy sources serving as an alternative tofossil fuel generated electricity and is known as a widely distributed clean and renewable sourceof energy. It is now the world’s fastest growing energy source and has also become one of themost rapidly expanding industries. READ MORE

4. Noise, eigenfrequencies and turbulence behavior of a 200 kW H-rotor vertical axis wind turbine
Abstract : Vertical-axis wind turbines (VAWTs) have with time been outrivaled by the today more common and economically feasible horizontal-axis wind turbines (HAWTs). However, VAWTs have several advantages which still make them interesting, for example, the VAWTs can have the drive train at ground level and it has been argued that they have lower noise emission.

5. Improved performance characteristics of induction machines with non-skewed symmetrical rotor slots
Abstract : Induction machines convert more than 55% of electrical energy into various other forms in industrial and domestic environments. Improved performance, especially by reduction of losses in induction machines hence can significantly reduce consumption of electricity. READ MORE
