Doctoral Researcher in Simulation of Variable Speed Electric Machines with Advanced Magnetic

We are currently seeking one highly motivated doctoral researcher to join the Department of Electrical Engineering and Automation at Aalto University, Finland, within a project focused on implementing advanced models of soft magnetic materials in accurate simulation software. The developed laminated‑steel models will be evaluated using an experimental setup equipped with variable‑speed electric machines. The objective of this evaluation is to determine whether the proposed model improves the prediction of additional losses introduced by the manufacturing process.

The successful candidate will contribute to research on generalizing some advanced magnetic material model developed at Aalto University. The focus on anisotropy and punching deterioration will enable the effective incorporation of detailed material models in design tools for the next-generation variable-speed electric machines feed by frequency converters. The development and implementation of the magnetic model into a finite-element-based software toolbox will be at Aalto University. The experimental validation will include sample-level characterizations as well as measurements on electric machines of varying power rating and machine topologies. The machine-level studies will be carried out in cooperation with ABB Corporate Research Sweden, Västerås.

Research Focus

The doctoral researcher will focus on topics including (but not limited to):

• Experimental characterization of several grades of laminated steels for electric machines whose magnetic properties are subjected to manufacturing-related degradation (e.g., mechanical stresses due to punching)

• Generalizing the model of magnetic deterioration to account for the residual mechanical stresses due to the punching process on electric steels of different grades and thicknesses.

• Contribute to the implementation of the dynamic vector models in the finite element code

• Numerical analysis of additional losses in the operating conditions of simulated variable-speed electric machines

• Validate the developed simulation models by experimental evaluation of the additional losses in the variable-speed electric machines

Requirements

Eligible candidates should have

• Master’s degree in electrical engineering, computer science, materials sciences, or a closely related field

• Fluent written and verbal communication skills in English

• Ability to work both independently and collaboratively as part of a research team
