E-Motor Weight and Cost Reduction Webinar
Nowadays, it is more and more challenging to design an e-motor. Many constraints have to be fulfilled, including maximizing power using minimal size, considering thermal constraints, material and production costs, and of course reducing weight. In order to meet these constraints, a multifaceted solution is needed, leveraging physics tools in combination with optimization methods.

Improving Electric Vehicle Range with Advanced Losses Computation Considering PWM Across a Full Duty Cycle
Introducing electric traction in automotive brings new challenges for the design of electric machines. Nowadays designers have to consider increasing constraints like efficiency, temperature, weight, compactness, cost but also stricter regulations, while reducing time to market. Fortunatly, Altair proposes disruptive methodologies to make relevant choices in the early stage of the design, based on numerical simulation and optimization techniques.

Once the machine has been selected and designed in Altair FluxTM this webinar covers how an electric motor design's performance is evaluated and maximized considering its global efficiency along the whole driving cycle.

The next design challenge is to get an accurate estimation of the losses, which becomes more and more strategic in the design process in order to accelerated speed to market with balanced design and confidence. This estimation is also a key issue of thermal design. Therefore, the study of losses (in particular non-conventional losses) is crucial. Two methods are proposed to take the current wave form into account: by using an equivalent circuit model in Altair ActivateTM system modelling software, or by representing the PWM in Flux circuit context.

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.
