Acoustic Noise Analysis and Reduction of Electric Motors: Using Numerical Electromagnetic, Mechanic and Acoustic Finite Element Method Noise Modelling

In this thesis, the acoustic noise emitted by a small electric outrunner motor, such as the ones commonly used in unmanned areal vehicles, is analyzed using a multiphysics simulation based on the finite element method. The simulation covers the electromagnetic, mechanical and acoustic domain. The electromagnetic simulation is performed in the 2D...

Design and Optimization of Linear Doubly-Fed Induction Machine for Wireless Charging Operation of Novel Vactrain System

With the aim to reduce the CO2 emissions in the transportation sector, there have been significant developments in the recent few years where novel ground transport systems operating at airline speeds using all-electric propulsion have emerged to provide a sustainable alternative to classical methods of <br/>transport such as air travel. These...

Optimisation of Interior Permanent Magnet Generator in Propeller Type Tidal Turbines

Over the past few decades, there has been a steep increase in efforts to generate electricity from clean and renewable energy sources so as to reduce consumption of fossil fuels. A considerable amount of research is in progress to explore the scope of various sustainable power sources; among which tidal energy is estimated to have a huge...
