Bental Motion Systems, a member of the Gevasol Group, has been designing and manufacturing advanced power and motion systems for demanding industries such as defense, aerospace, and semiconductors since 1983. The company produces a variety of end applications including motors, alternators, and electrical brakes. To meet increasing demands, Bental continues to advance its in-house capabilities in development, analysis and design, testing, and quality assurance. However, the company faced a challenge in accelerating the design of electric machines while reacting quickly to customer-specific requirements. The R&D team needed to extend its usage of the Altair software suite to cover more physics and gain flexibility in their approach depending on the project phase.

Bental Motion Systems is a member of the Gevasol Group and has been in operation since 1983. The company specializes in designing and manufacturing advanced power and motion systems for demanding industries such as defense, aerospace, and semiconductors. Bental produces a variety of end applications including motors, alternators, and electrical brakes. The company is committed to meeting increasing demands by continually advancing its in-house capabilities in development, analysis and design, testing, and quality assurance. The R&D group, led by three post-graduate PhD designers, enables quick response and turnaround.

Bental Motion Systems adopted Altair's suite of software solutions to address their design challenges. Altair FluxMotor™ was used for motor pre-design, enabling quick concept exploration and accurate feasibility checks. The team also referenced previous designs stored on their company server to gain quick insights and select the most appropriate starting point for a new design. Once feasibility was approved and validated with the customer, the complete FluxMotor project was exported to Flux2D for detailed electromagnetics design and thermal simulations. For more specific analysis, Flux 3D was used to check the machine's magnetic field surrounding, predict the winding head temperature, and perform axial direction analysis. Altair Inspire™ supported the team when a more global approach was required, and Altair AcuSolve™ was used for advanced thermal analysis. The increasing use of Altair HyperStudy™ for data exploration and multiphysics optimization showed promising possibilities for innovation and performance optimization.

• The adoption of Altair's software suite has significantly transformed Bental Motion Systems' design approach. While some designers still sporadically use their spreadsheets with analytical formulas, the increasing use of Altair software has supported them to completely rationalize their design approach, and create a customized workflow for their needs. They are now able to consider more configurations with multidisciplinary constraints, make decisions faster, and work closely with their customers at different design stages to meet their needs. This has enabled them to produce efficient and sustainable equipment.
