This is a PhD dissertation. The work presented in this monograph was carried out at the Department of Power Electronics and Electrical Machines, Faculty of Electrical and Control Engineering at the Gdansk University of Technology. Developed during the research models of brushless synchronous generator ware verified using FEM based simulations and measurements conducted on the prototype generator. The main focus of the research was toward a brushless synchronous generator in variable frequency modern more electric aircraft power systems. The generator prototype was developed and its performance was analyzed with the focus on the higher rotational velocity of the prototype components and the generated power quality. For this FEM based and circuit models of the generator ware developed and the machine performance was measured and simulated. The proposed circuit model allowed for the inclusion of nonsinusoidal spatial distribution of the magnetic flux along the air gap which in turn allowed for simulation-based power quality analysis.

Off-Grid Living: How To Build Wind Turbine, Solar Panels And Micro Hydroelectric Generator To Power Up Your House (FREE Bonus Included) Book 1: Go Off Grid And Go Green With Micro Hydro System: How A Micro Hydro System Can Provide Your Off-Grid Home With Electricity
When we think of renewable energy, most of us think solar or wind, but another choice does exist, hydroelectric. Using water for power goes back to water wheels and culminates in huge hydroelectric dams. There is middle ground too; small hydroelectric systems can power a home as efficiently as solar power. Stop paying enormous electric bills and never worry about the power going out again
It is possible to go off grid and rely on hydroelectricity for power and this book will show you how. All you need is a stream, creek, or river on your property and you will never have to pay an electric bill again You may even end up getting money from the electric company for the electricity you produce In some cases, you can go completely off grid, for others, this renewable energy can provide the power needed when power from the grid is not available.
Book 2: DIY 400 Watt Wind Turbine: Build Your Own Efficient Wind Turbine In Just $200
This book is going to change the way you think about the wind, and the way you rely on the modern day use of power. You don't have to be a master with woodworking or tools, you just need the right set of directions and a few basic skills, and you can make your own wind turbine.
