Instead of designing motor components one after the other, Porsche and Altair have teamed up to use simulation to do it all at once


he rate of which electric hybrid and full-electric vehicles are reaching the market and being developed has increased

considerably over the past years and the requirements on the e-motors being designed for new cars are increasing rapidly as well. The goal is to develop better motors within tighter time and cost schedules. Simultaneously, the technical requirements on the motors are increasing rapidly, both in terms of level and bandwidth of requirements. Today, an e-motor cannot just be developed looking at the motor as an isolated unit; it must be assured that tight requirements concerning the integration

into both the complete electric or hybrid drivetrain system and tight requirements concerning perceived quality are fulfilled. Thus, it is a necessity to develop the e-motor not in isolation but as a

system to fit optimally with other components and systems. Noise and power consumption are two of such integration challenges. FE and other simulation methodologies

have traditionally been used very successfully to verify designs and design directions. Today, FE and especially numerical optimisation is increasingly used to support and drive the design process, i.e. optimisation is used to help the design team find best alternatives, executing sensitivity studies, performing trade-offs between different design alternatives, and so on. This design strategy is often denoted ‘simulation- driven design’. It’s especially beneficial where the design is less intuitive because of high design complexity and/ or complexity of loads and targets for the design. Products and designs that experience requirements from several different types of physics and attribute disciplines are especially suited for using simulation-driven design since it quickly becomes impossible to comprehend the
