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.

Coupled Electro-Magnetic and Acoustic Simulation of an In-Wheel Electric Motor

At Elaphe, the engineers have been facing the NVH challenges from the very beginning. The topology of this electric motor, which on the one hand enables the team to use the otherwise empty space inside the wheel, can on the other hand, result in some new and unexplored NVH challenges. The experience over the years has proven that NVH is a bottleneck in the design cycle of Elaphe's motors and this was the main motivation for a more automated and more user-friendly NVH simulation workflow. Within the NVH, noise radiation was the area Elaphe was most interested in.

Using Multiphysics Optimization to Design High Performance Rotating Machines

Light-weight, low cost, compact, high efficiency are some of the many objectives and constraints that have to be considered when designing a rotating machine. To meet these various challenges it is necessary to take into account several physical aspects: - electromagnetic - structural - thermal This presentation shows how Altair HyperStudy can involve several Altair solvers to consider different requirements into a single optimization and will be illustrated through various examples.

Considering Temperature Constraints in the Design of Electric Machines

Because of always more compact and high efficiency systems, temperature is a critical constraint in electric machine design. Depending on the design stage, different levels of modeling can be proposed: - 1D for fast pre-design, to - full 3D CFD models for the validation stage. This presentation shows, through a complete example how the Altair platform for innovation helps machine designers to manage temperature distribution and evolution.

Thermal Analysis of Electrical Equipment A review and comparison of different methods

Nowadays, it is more and more difficult to design electro-technique devices without having a look at thermal stress. In more and more applications (more electric vehicles, more electric aircrafts, …) designers need to reduce weight, cost, increase efficiency, and keep the same security factor. One possibility is to increase current for the same device, needing to check how to draw away the heat. This is why the classical approximations need to be cross checked with complementary analysis. These new tools have to be rapid and accurate in order to run parametric and even optimization analysis. There is also a need for fast model in order to check robustness versus driving cycles. The goal in this article is to review rapidly the different methods available, depending on the accuracy required and the solving speed. The method includes equivalent thermal circuits, Finite elements methods and CFD analysis.
