Spijkers, R.A. (author)In 2011, AUDI AG and four other German car manufacturers decided to implement an additional 48 V on-board power network inside cars. This offers the opportunity to increase the number of electrical applications in the car, to increase the fuel efficiency and to decrease the CO2 emissions. In order to achieve this, the current electromechanical...master thesis 2015

Hossain, M.R. (author)The number of installed wind turbines is growing every year as the need for energy increases in an exponential manner. As the wind turbines are trying to fulfill these requirements, the demand for output power from each individual turbine is increasing as well. Although this is great, implementation of new technologies such as direct drive...master thesis 2014

Smet, D. (author)With the ongoing developments in the offshore wind turbine industry, weight reduction is an important aspect. With these weight reduction, manufacturers are trying to increase the effciency and size of their turbines. An example of such a technique is a single bearing drive train. These designs use a special bearing which is extra stiff due to...master thesis 2014

Van de Wetering, R. (author)In this thesis the current distribution among parallel coils and the presence of circulating currents in an electric machine is investigated. Differences in induced voltage and in impedance between the parallel coils might lead to an uneven current distribution, which may cause the temperature of a single turn to become too high. To determine...master thesis 2013
