Introducing Multiphysics Workflows to Accelerate the Design of Electric Motor Driven Systems
Electrification is everywhere! It brings energy efficiency into systems and also helps add new smart functionalities to products. The electric motor is a key element of such systems, converting electricity into mechanical power. It is multiphysics by nature. Electric machine engineers need to take into account various constraints from the early stage of the design, looking at electromechanical performance, as well as respecting thermal and NVH constraints. Simulations need to integrate these multiple physics and also coupling effects. Dedicated tools and streamlined multiphysics workflows are developed in order to reduce complexity and speed up the design.

Electric Motor Design through Simulation Driven approach
This presentation is an overview of Rizel Automotive’s R&D journey towards developing an efficient and cost-effective Motor Platform with optimum characteristics for the automotive EV Space using Altair’s tools to solve electromagnetic, structural, NVH, and Thermal challenges and validate the Digital Designs and through Physical Testing.
All the way through the design process, Altair tools helped us in solving the complex problems which solve the core electric motor problems; like inductances calculation, cogging torque optimization, D axis conditioning, model analysis, transient thermal analysis which helped us in understanding and validating our analytical design and research.
With the help of Altair tools, we were able to implement and validate our novel ideas related to thermal design and come up with a unique motor architecture without compromising on electromagnetics. In this process, we have designed one of the lightest and compact radial flux motors in the industry.
Easy to use software from Altair, with a simple interface and automation tools; helped us to iterate, fine-tune our motors with high accuracy and a much quicker pace. And helped us to engineer a powerful yet silent and cooler but efficient motor.
From our recent dyno testing at ARAI, we were able to match the simulated data to dyno test results with a deviance of less than 5%, giving us great confidence in our Simulation Techniques and Altair’s tools, helping us decrease the Time to Enter the Market.

Cool Runnings: E-Motor Design at DEF
The idea for its cooling technology for electric motor systems was born at high-tech start-up Dynamic E flow (DEF), when the founders first experienced an overheated engine of an electrical car.
The existent development process at DEF used analytical methods and physical testing to confirm results. With increasing customization, that process was not flexible enough to handle various design possibilities. With the need for a simulative design approach, DEF employed Altair software to tackle its multi-physical design challenges, and to meet all the customer requirements for their unique motors, test hundreds of variants, and to check the feasibility of the customized product.

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.
