E-motor Design using Multiphysics Optimization
Today, an e-motor cannot be developed just by looking at the motor as an isolated unit; tight requirements concerning the integration into both the complete electric or hybrid drivetrain system and perceived quality must be met. Multi-disciplinary and multiphysics optimization methodologies make it possible to design an e-motor for multiple, completely different design requirements simultaneously, thus avoiding a serial development strategy, where a larger number of design iterations are necessary to fulfill all requirements and unfavorable design compromises need to be accepted.



The project described in this paper is focused on multiphysics design of an e-motor for Porsche AG. Altair’s simulation-driven approach supports the development of e-motors using a series of optimization intensive phases building on each other. This technical paper offers insights on how the advanced drivetrain development team at Porsche AG, together with Altair, has approached the challenge of improving the total design balance in e-motor development.

Programmable, Open-Architecture HyperWorks Helps Toshiba Design Smaller Hard Disk Drives to Meet Market Demand
Toshiba Digital Network Company, faced with increasing global competition in the hard disk drive (HDD) marketplace, set out to create an advantage through the redesign of their existing HDD product(s). To support this effort, Toshiba partnered with Altair Engineering to automate its design process. This was accomplished by leveraging HyperWorks powerful modeling, visualization and optimization software applications with Toshiba’s proprietary solver for fluid dynamics. The specific goal was to optimize the air bearing surface (ABS) of the HDD’s magnetic head slider. This unique product development process resulted in minimizing the flying height as much as possible while considering its stability. This, in turn, reduced the overall size of the HDD and increased its recording density. In addition, the new design was brought to market in significantly less time than with Toshiba’s traditional design process.
