Altair® FluxMotor®

Bental Motion Systems, a member of the Gevasol Group, produces a variety of end applications including motors, alternators, and electrical brakes for the aerospace & defense, and semiconductor industries. To accelerate the design of electric machines while reacting fast to customer specific requirements, Bental uses Altair FluxMotor to enable quick concept exploration including valuable predictions on machine performance, parameters, and productivity feasibility checks.

Permanent magnet motors are widely used in the development of electric vehicles (EVs). However, these devices are based on expensive, hard-to-recycle rare earth materials. Wanting to explore new boundaries in electric motor design and production, Spin started a project focused on replacing rare earths materials in these motors. To develop a more sustainable motor without using rare earth-based permanent magnets while still ensuring efficiency and meeting performance targets, Spin needed a tool that allowed them to study, evaluate, and improve every possible aspect of the motor’s behavior and performance before building a prototype. Thanks to the Altair® HyperWorks® platform and its multiphysics analysis capabilities, the Spin team made significant progress in developing a new, highly efficient product: the synchronous reluctance motor.

Electrification is revolutionizing how engineers design for mobility. Adopting a common parts design approach that integrates and reuses components and strategies within a unified design and simulation platform ensures e-motor designs achieve the optimal balance between efficiency, performance, sustainability, and cost. Altair e-Motor Director combines multiphysics optimization with data-driven design in an automated and customizable design environment that reduces development time to hours and days instead of weeks and months.

The comprehensive design process of a typical engine for this application developed by Heroux-Devtek Spain will be presented, from the derivation of requirements for the engine from a high-level specification to functional bench testing. Special attention will be paid to the design, development, optimization, and verification processes of the functional capabilities of said engine using the Altair tools FluxMotor, HyperStudy, and Flux2D. High temperature environments impact on winding, isolation materials, and electronics will be addressed as a starting point of new challenges increasingly demanded by the industry.
