Replacement of traditional combustion engines with an electric powertrain, bring electro-mechanical induced tonal and high-frequency whine noise. In addition, tire and aerodynamic turbulent noise become more prominent in the absence of a standard Internal Combustion Engine. Also, the perceived sound quality imposes a new set of challenges. This leads to completely new methods of NVH refinement, keeping the decades of research aside. As it is important to address these issues at the design and development stage, adopting the new simulation techniques to manage future NVH challenges in e-Mobility is of the prime challenge to the traditional NVH engineers. In this webinar, we shall discuss some of those key NVH challenges specific to electric vehicles and appropriate simulation processes to develop countermeasures.

Traction Motor play key role in the electric vehicle/hybrid electric vehicle (EV/HEV) development process. The design of a High-Performance e-Motor is a complex undertaking. Engineers have conflicting constraints to consider including efficiency, temperature, weight, size, and cost. To explore more ideas, better understand their designs and improve performance, Altair HyperWorks™ has a workflow to guide motor designers through an efficient process of Simulation-Driven Design. This analysis and optimization solution supports multi-disciplinary teamwork and reduces design times.

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. This webinar will introduce Altair's e-motor design and optimization solutions in a step by step process. We will discuss pre-design, magnetic computation and thermal analysis and show how optimization methods can help to optimize weight and cost at each step of the process (especially the weight of magnets) . We’ll demonstrate how Design Of Experiments (DOEs) allows designers to run different types of optimization very quickly, which enables informed decisions at different stage of the design 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.

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.
