[JAC297] Geometry Optimization of a Wound-field Synchronous Motor Including Efficiency Map, Part Temperature, and Stress Evaluations
Designers often have to rework initial motor designs that only tackle the magnetic design because subsequent processes discover that these initial designs do not satisfy the part temperature and stress requirements. An initial design process that not only addresses the magnetic circuit but also runs heat, stress, and other multi-disciplinary evaluations enables designers to reduce any rework and explore optimal designs. Wound-field synchronous motors (WFSM) do not require rare earth magnets and expand the fixed output range by varying the magnetic field but do come with drawbacks, such as higher temperatures due to copper losses in the field coils.
Optimizations using simulations can automatically explore numerous design ideas in a large design space to obtain optimal design proposals. The templates provided by JMAG-Express make it simple and easy for users to create motor models, run optimizations, and evaluate design ideas. Users can combine various JMAG-Express scenarios to run optimizations that take into account the magnetic fields, temperatures, and stress all at the same time.
This case study runs a parametric optimization of a main automotive engine to maximize efficiency and torque while minimizing the temperature and stress as constraint conditions.
