MSc Thesis: Tonal Noise in Permanent Magnet Machines

About the role

ABB Corporate Research in Västerås, Sweden, is offering an MSc thesis (30 ECTS, one student) in the Materials Technology & Electromagnetics team, reporting to the R&D Team Lead. The work focuses on tonal noise in Interior Permanent Magnet (IPM) machines, where the increasing use of electric machines makes e-NVH a key challenge. The thesis uses simulation and measurement data to identify the key e-NVH features behind tonal noise.

Key responsibilities

• Conduct 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 prediction.
• Identify the key factors governing tonal-noise generation and assess their relative importance.

Required profile

• MSc 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.

The position starts in January–June 2027. Applications are made through the ABB careers site with a CV, academic transcripts and an English cover letter.
