L’optimisation multiphysique pour la conception des machines électrique de traction
Information
To design efficient electric motors for
automotive applications, it is necessary to consider
constraints from different physics: size, weight, torque
density, temperature, and vibration. With the time to
market pressure of new vehicle models, finding
optimized topologies of motors has to be done in a
short time. At the early stage of the design, when
looking at various solutions, quick assessment of
machine performances is needed, with all physical
constraints being considered. A new methodology
taking into account all these aspects is presented in
this paper. A fast concept design tool associated to
design of experiments (DOE) analysis and surface
response-based optimization is proposed. It is applied
to a traction motor example where rotor design
parameters can be changed.
