The Next Generation of Rotor Design: Topology Optimization Meets Air-Pocket Design
Electromagnetics
PRESENTER:
Daniel Romanowski, Daimler Truck AG
EXPERTISE:
Electromagnetics
Software:
JMAG
Conventional, parametric design approaches limit the solution space to predefined geometric parameters. Topology optimization expands this space through the free distribution of material within a design domain, enabling more capable designs. Since this requires significantly more designs to be calculated, a larger number of licenses (PSL vs standard) is needed to reach an optimal result within a reasonable optimization timeframe.
In the application scenario “Air Pocket Optimization,” the optimal distribution of air pockets within the rotor is investigated with the magnet in a fixed position. The model setup, objective functions, and boundary conditions are presented, along with an evaluation based on a reduced-order model using version 24.2.
Finally, the topology-optimized design is compared with the parametric reference design based on key KPIs. The conclusion and outlook focus on the combined optimization of air pockets and magnet position.
