Siemens Digital Industries Software recently announced new releases of Siemens Simcenter MAGNET software and Simcenter Motorsolve software for simulating electric motor design and electromagnetic fields at any stage of the design process. Electric traction motors must be durable and NVH-compliant, however, electromagnetic forces induce mechanical vibrations which may lead to failure. The Simcenter MAGNET and Simcenter Motorsolve solution calculates the behavior of electromagnetic forces on individual components, providing examination of the structure and materials integrities under multiple operating conditions during any phase of the design process. These new capabilities are important for implementing a realistic digital twin of electric and hybrid electric vehicle powertrains or for any application where NVH constraints are critical, such as aerospace, industrial and medical equipment. 

Siemens’ approach to NVH analysis is unique since the Simcenter Motorsolve tool uses smart 2.5D technology to generate a 3D nodal force mesh model based on 2D simulations, significantly accelerating analysis with accurate results. Net forces on components can be determined using Simcenter MAGNET software, even when they are in contact, including artificial component grouping. Simcenter SPEED PC-BDC models can be seamlessly imported into Simcenter Motorsolve software for higher-resolution finite element simulations, and Simcenter 3D electromagnetic software integration can provide optimal electric motor simulation performance results. Now, design engineers can apply a wider range of real-world conditions in their electro-vibro-acoustic simulation analysis.

Siemens provides the most comprehensive automotive and transportation software portfolio in the industry, combined with an application development platform to accelerate the efforts of engineering teams to innovate with confidence. Automotive manufacturers, suppliers, technology startups and industry leaders apply Siemens comprehensive digital twin to create the most robust digital representation of automotive systems and real-world environments, blurring the boundaries between engineering domains, and between the digital and physical worlds. 

“Our Simcenter MAGNET and Simcenter Motorsolve solution addresses the key challenges electric motor designers face for NVH compliance,” stated Roland Feldhinkel, vice president simulation and test solutions, Siemens Digital Industries Software. “As a leader in automotive software technologies, the new functionality in our latest release can quickly identify design problems so our customers can develop high-performance products with greater productivity.”
