At ABB, we help industries outrun - leaner and cleaner. Here, progress is an expectation - for you, your team, and the world. As a global market leader, we’ll give you what you need to make it happen. It won’t always be easy, growing takes grit. But at ABB, you’ll never run alone. Run what runs the world.This Position reports to:R&D Team Lead Details:· Period: Start Jan-June 2027· 30 ECTS per student· Number of students: 1· Location: ABB Corporate Research in Västerås, SwedenYou will be part of Materials Technology & Electromagnetics team at ABB Corporate Research in Västerås, Sweden. At Corporate Research we lead the innovation within ABB and our task is to ensure ABB's technology competitiveness now and in the future. We work in close collaboration with other research centers, our business areas: Motion, Automation and Electrification, as well academic and industrial partners. In our creative and highly skilled team we develop, design, build and test new concepts and prototypes of physical and digital powertrains or electrical devices. The increasing use of electric machines has made tonal noise an important e‑NVH challenge. In Interior Permanent Magnet (IPM) machines, tonal noise is mainly driven by electromagnetic force harmonics, structural resonances, and their interaction with the acoustic response. This thesis aims to improve the understanding of tonal noise generation in IPM machines using simulation and measurement data. The work will focus on identifying the key e-NVH features related to tonal noise.Your role and responsibilitiesConduct a literature review of existing methods for e‑NVH and tonal-noise analysis.Work with simulation and measurement e-NVH data.Apply signal-processing techniques to identify relevant noise features.Explore data-analysis and machine-learning methods for tonal-noise predictionIdentify the key factors governing tonal-noise generation and assess their relative importance.Qualifications for the roleMaster of Science student in Mechanical Engineering, Engineering Physics, Computer Science, or a related field.Good understanding of signal processing concepts, such as FFT and frequency-domain analysis.Programming and data-analysis skills; prior experience with machine learning is an advantage.Basic knowledge of electric machines is beneficial.Willingness to learn how to use Multiphysics simulation tools.More about usRecruiting Manager David Lindell , 46 72 461 35 03, will answer your questions.
