Innovative E-Mobility Solutions - Designing silent, lightweight and efficient electric motors


"The development of the next generation of Electric Machines can only meet the performance, efficiency and levels of sustainability required in response to market demand by leveraging the full potential of state-of-the-art digital tools and methods. A key success factor in achieving these goals is by using holistic development approaches based on Simulation-Driven Design and multi-physics optimization, something that we are excited to be exploring with our Simulation-driven Innovation partner Altair across a range of special talks and case studies at CWIEME Berlin this year"

Porsche White Paper:
E-motor Design using Multiphysics Optimization

The rate of which electric hybrid and full-electric vehicles are reaching the market and
being developed has increased significantly over the last years and the requirements on the e-motors been 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 being developed are increasing rapidly, both in terms of level and bandwidth of requirements.

Elaphe Technical Paper:  
Coupled Electro-Magnetic and Acoustic Simulation of an in-wheel Motor


Noise, vibration and harshness (NVH) is becoming one of the key aspects of electric mobility and in-wheel motors are no exception. With high torque and high performance, in-wheel motors can cover a wide range of vehicle applications. At the same time, these high-power electric machines need to be designed in the right way in order to meet increasingly strict NVH regulations. Find out how Elaphe, using the NVH workflow, has been able to decrease the noise of the most critical range of frequencies to as much as 20 dB.

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.

Improving Electric Vehicle Range with Advanced Losses Computation 

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.

This webinar covers how an electric motor design's performance is evaluated and maximized considering its global efficiency along the whole driving cycle.

E-Motor Weight and Cost Reduction with Efficient Design and Optimization 

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.

Why Altair Inspire Cast
Design for Castings
Radically new designs in combination with new materials demand designers to evaluate their designs early. Engage early with Altair Inspire Cast to simulate possible issues upfront with minimal or no training. As the process gets refined the ability to further investigate and optimize the process makes Altair Inspire Cast uniquely valuable during the entire product development cycle from early design to manufacturing.
Minimize Process Complexity
It is typical in the industry to first design a process and then simulate it. Altair Inspire Cast turns that concept overs its head by helping users evolve the process in tandem with their ideas. You can start the filling with virtualized in-gates that will guide you through areas of porosity and the right risers to compensate. Gravity, Die, High Pressure, Low Pressure, Investment and Tilt casting, all have guided templates for refinement.
Improve Quality and Profitability
State of the art, bi-phasic Finite Element formulation allows for capturing the filling and solidification process with great precision. This helps with building great quality castings with high margins.
