1. On Inter-bar Currents in Induction Motors with Cast Aluminium and Cast Copper Rotors
Abstract : This thesis presents a study of the effects of inter-bar currents on inductionmotor starting performance and stray-load losses. The work is focused on theperformance differences between aluminium and copper casted rotors.A method to predict the stator current when starting direct-on-line isdeveloped. READ MORE

2. Analysis and Reduction of Parasitic Effects in Induction Motors With Die-Cast Rotors
Abstract : This thesis presents a study of inter-bar current effects on induction motors with die-cast aluminium and die-cast copper rotors. The parasitic effects introduced by these currents are analyzed and possible solutions to these problems are presented. This is realized by developing analytical tools for the simulation of inter-bar current effects. READ MORE

3. 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

4. Development of Dual-broadband Rotational CARS for Combustion Diagnostics
Abstract : The present thesis concerns development and application of dual-broadband rotational coherent anti-Stokes Raman spectroscopy (DB-RCARS) for temperature and species concentration measurements in combustion processes. Both fundamental development of the technique, including experimental as well as modelling results, and measurements in practical combustion devices were conducted. READ MORE

5. Design Aspects of Inductive Power Transfer Systems for Electric Vehicle Charging
Abstract : During the last decade the transition towards electric propelled vehicles has had an upswing and electric vehicle (EV) sales has increased steadily. This is much due to legislations on lowering emissions but also due to lower total cost of ownership. READ MORE
