这简化了 e-Motor Director 在客户环境中的集成，在客户环境中，电机设计流程已经开发并部分自动化。 这些用户定义的解决方案简化了将现有流程迁移到 e-Motor Director 中的过程。
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.
Dr. Lars Fredriksson, VP - Simulation Driven Innovation at Altair, presents the multi-physics design of e-motors with a particular focus on optimising performance including efforts to maximize torque and power under defined driving conditions while keeping rotor stresses, motor vibrations and motor temperature within certain limits. We’ll also see some specific examples of this process as applied to e-motor development at both Porsche and AMG.
Future e-motors must be developed to fulfil more and higher requirements originating from internal, legal and customer sources. Failure to fulfill design targets will negatively affect the product competitiveness in the market.
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.
