Study of magnetic force excitations in salient pole synchronous generators considering geometrical modifications by conformal mapping

Autor: Kevin Jansen, Alexander Kern, Christoph Mülder, Kay Hameyer

Publikováno v: International Journal of Applied Electromagnetics and Mechanics. 69:139-147

The simulation of electrical machines at the first design stage requires efficient methods to characterize among other properties its vibrational behavior. Particularly when considering both designed and parasitic geometrical modifications, magnetic

Electromagnetic Study of Direct-Driven Wind Turbine Generators by Coupled Field-Circuit Simulations and Full-Scale Bench Tests

Autor: Christoph Meier, Fabian Müller, Christoph Mülder, Kay Hameyer, Andreas Thul

Publikováno v: 2021 IEEE Energy Conversion Congress and Exposition (ECCE).

Studying the electromagnetic behavior of gearless wind turbines, related to parasitic excitation of vibrations and audible noise emission, comes to the fore of science. Reliable simulation and testing methods are essential in this context. The electr

Hybrid Approach for the Modeling of Magnetic Force Excitations in Multipole Wind Turbine Generators Considering Air Gap Imperfections

Autor: Kay Hameyer, Alexander Kern, Jianning Dong, Christoph Mülder

Publikováno v: 2021 IEEE Energy Conversion Congress and Exposition (ECCE): Proceedings
2021 IEEE Energy Conversion Congress and Exposition (ECCE)

Magnetic force excitations in the air gap of generators can lead to tonal noise emissions of direct-drive wind turbines. Besides the magnetic circuit design, the generator air gap topology has an impact on the excited vibration modes and their freque

Impact Study of Isolated and Correlated Manufacturing Tolerances of a Permanent Magnet Synchronous Machine for Traction Drives

Autor: Michael Schröder, Andreas Wanke, Markus Balluff, Kay Hameyer, Christoph Mülder, Marius Franck

Publikováno v: 2019 IEEE International Electric Machines & Drives Conference (IEMDC).

In the course of a growing market share of electrified vehicles, electrical machines will be manufactured in a large scale. The production of high quantities leads to a scattering of the final geometries of e.g. the electrical steel sheets or bearing

Digital processing of images of extruded rubber profiles for process control MRI

Autor: Josefina Perlo, Ernesto Danieli, Christian Hopmann, Christoph Mülder, Federico Casanova, Bernhard Blümich

Publikováno v: Measurement. 82:466-475

Magnetic resonance imaging (MRI) is a powerful technique in materials science, in particular for the analysis of polymer and rubber materials. So far the use of this technique for quality control has not been fully explored mainly because of the proh
