Comprehensive Multiphysics Design for Electric Machines

Dear Desktop Engineering Reader: 

Today’s Check it Out link takes you to an intriguing Web resource on electric motor design and simulation. What you learn here is that a multiphysics virtual prototyping workflow lets you explore the design variables of electric motors deeply and efficiently. This enables you to challenge your design assumptions and correct the bad ideas before you’re too deep in the process that you run up a huge bill fixing them.

When you land at ANSYS’ new “Comprehensive Multiphysics Design for Electric Machines” Web page, you’ll see three resources: a video, a white paper and an application brief. Start with the three-minute video (registration free). It’s a narrated demonstration of a coupled multiphysics prototyping workflow using ANSYS’ electromagnetic, thermal, mechanical and acoustics solvers to design and develop an electric machine.

The demo video takes you from analytical pre-design through testing. It shows how you can couple multiple physics tools to study the temperature dependency of permanent magnets, analyze vibration and deformation effects and perform detailed electromagnetic design.

The ANSYS Workbench platform provides the framework coupling the solvers. ANSYS RMxprt, a template-based design tool that enhances the ANSYS Maxwell electromagnetic field simulation software, ANSYS CFD (computational fluid dynamics) and ANSYS Mechanical FEA (finite element analysis) toolsets are featured. As you might imagine, the video has many neat animations.

The “Electric Machine Design Methodology: A Revolutionary Approach” white paper builds off the video’s themes by providing a broad overview of the ANSYS electrical machine and drive design approach. This paper explains the multiphysics and multi-scale system engineering technologies the company offers and their benefits to hands-on engineers, their companies and clients. The paper is well illustrated and readable by a wide audience.

A new Web resource from ANSYS offers a demonstration video titled “Multiphysics Design Flow for Electric Motors” from which this image was screen-captured. Image courtesy of ANSYS Inc.

The application brief, “Advanced Design of Electric Machines Using the ANSYS Electric Machine Design Toolkit,” provides the hardcore technical story. Here, you step through the creation of efficiency maps for a traction motor. Accompanying the brief is a short case study on how a leading provider of automotive electronic systems validated the ANSYS electric machine simulation tool through measurements.

The “Comprehensive Multiphysics Design for Electric Machines” Web resource is a tutorial for existing ANSYS users and, most likely, an eye-opener for others. This resource is professionally executed, a snap to negotiate and highly informative. Hit today’s Check it Out link and dig in.

Thanks, Pal. – Lockwood
