This applied project deals with simulation-based optimization in electric motor design. The task is to tune a number of design parameters specifying the geometry and material properties of motor components in such a way that technological constraints are satisfied and various objectives optimized. The focus is on minimizing the cogging torque of the motor. The project relies on randomized optimization techniques integrated with a numerical simulator of the motor, and exploits surrogate models and parallelization to speed up the optimization process. Of particular interest is potential improvement of the motor design with respect to the objectives as well as the robustness of the optimized solutions.

The project is being carried out for Mahle Electric Drives Slovenija, a member of the Mahle Group.
