Enhanced electromagnetic-vibro-acoustic analysis – Siemens solution accelerates the development of electric traction motors

Simcenter Motorsolve makes it simple and quick to generate the force export so that NVH analysis can be performed early in the design process, ensuring reliability and durability of the machine.

With the new releases of Magnet and Motorsolve, electric motor design and electromagnetic fields can be simulated at any stage of the development process. The motors must be durable and compliant in terms of NVH (Noise, Vibration, Harshness). However, electromagnetic forces and vibrations have an adverse effect. These interference factors must be eliminated as far as possible in order to protect the motor. Using Siemens software solutions, developers can calculate and examine the effects of these forces and vibrations on each individual component and test the material integrity under various operating conditions. A digital twin of electric and hybrid powertrains can be created.

Comprehensive portfolio for optimal design process

The Siemens solution offers numerous functions that provide design engineers with the ideal range of analysis and design options. For example, the Simcenter Motorsolve software uses smart 2.5D technology to generate a 3D nodal force mesh model based on 2D simulations. The forces that actually act on individual components can be determined using Magnet software. In addition, for higher-resolution finite element simulations, Simcenter Speed PC-BDC (synchronous machines) models can be seamlessly imported into Motorsolve software. The new releases of Motorsolve and Magnet software provide engineers with a portfolio that can be used to develop even complex structures and systems quickly and efficiently. “Our Simcenter Magnet and Simcenter Motorsolve solution addresses the key challenges electric motor designers face for NVH compliance,” explains Roland Feldhinkel, Vice President Simulation and Test Solutions at Siemens Digital Industries Software. “The new functionality in our latest release can quickly identify design problems so our customers can develop high-performance products with greater productivity.”
