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"

Technical Papers

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.

Fast Assessment & Optimization of the Energy Efficiency of Electric Machines

In the early stage of the design of an electric machine, it is key to assess its potential in terms of global energy efficiency when submitted to specific duty cycles.
This webinar shows how Altair FluxMotor is able to extract efficiency maps in a very fast way. It can an be coupled to Altair HyperStudy for design exploration and optimization studies, considering the efficiency over duty cycles as an objective function to be maximized.

Using Multiphysics Optimization to Design High Performance Rotating Machines

Many objectives and constraints 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.
In this webinar we show how Altair HyperStudy can involve several Altair solvers to consider different requirements into a single optimization. This 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 webinar shows, through a complete example how the Altair platform for innovation helps machine designers to manage temperature distribution and evolution.

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.
