Advanced e-Motor Design Dedicated Environment - Altair Flux FeMT

By combining computationally efficient reduced-order models and detailed CAE analysis with process automation of repetitive and tedious tasks, Altair provides workflows for early system models, mixed-fidelity simulations, and multiphysics validations, across domains including electrification or advanced manufacturing. In this example, we're showing the end-to-end multiphysics optimization cycle of an electric motor, reducing the simulation process time from weeks to hours.

Altair Flux offers a direct model export compatible with major system simulation software for straightforward system integration. Two different formats are available: FMU (Functional Mockup Units) dynamic models format is straightforward, standardized and very efficient, while lookup tables are an interesting alternative, offering the opportunity to adjust the dimensions of the table according to the required precision. Latest improvement enable impressive speed-up with Altair Activate™.

Altair FluxMotor is a straightforward platform dedicated to the pre-design of electric rotating machines. It enables the designer to build a machine from standard or customized parts, add windings and materials to quickly run a selection of tests and easily compare the machine performance. In addition, they can predict the machine performance at one or more working points, and also for complete duty cycles. By coupling FluxMotor to Altair HyperStudy design exploration and optimization solution, Altair offers designers a unique process to optimize their motor concept at an early design stage. They can select and focus on the topologies that fulfill the main specifications before going further in their EM design with Altair Flux and perform Multiphysics analysis.

Designers starting with a blank page face an unlimited number of configurations and need to quickly select machines types. By coupling Altair FluxMotor to Altair HyperStudy design exploration and optimization solution, Altair offers designers a unique process to optimize their motor concept at an early design stage, defining their constraints and their objectives. A typical objective is to reach maximum global efficiency across a given duty cycle. Then, designers can select and focus on the topologies that fulfill the main specifications before going further in their design.

Once a designers has defined its motor concept in Altair FluxMotor and evaluated its global performance, he can perform more detailed analysis, exporting his machine in Altair Flux and working with high-fidelity models. Significantly, Flux enables more accurate prediction of motor behavior, with advanced losses computation, considering eccentricities, magnet demagnetization, effects of manufacturing process, and couple to Altair HyperWorks for multiphysics analysis.
