Advanced Electric Machine Design with Electromagnetic and CFD Simulations

You may have read a quick blog post at Desktop Engineering about ANSYS’s electric machine simulation capabilities. Here we dive into the technical aspects and implications of thermal simulation for electric machines.

Electric machine geometry with cooling and integrated power electronics.

Electric machine geometry with cooling and integrated power electronics.

Modern electric machines are designed to meet a wide range of applications, all facing a variety of different technical challenges. They are designed to be compact with high power densities, to have integrated power electronics, to be high-speed for higher power density, and to handle harsh environments.

These challenges all have thermal implications that affect the lifetime and performance of the electric machine and power electronics, and must be balanced with cost goals. ANSYS simulation tools, Fluent and Maxwell, can be used to predict the thermal and electromagnetic performance of these systems, and can therefore be used to optimize design choices for both thermal and cost considerations while meeting all application objectives.

ANSYS 16.0 Targets Electromechanical and Power Electronic Design

Vehicle electrification, renewable energy, and power delivery applications continue to be major trends driving innovations in the industrial, automotive and aerospace sectors. “Good old designs” of power systems and electrical machines using a build-and-test methodology are out of date. Products using the old approach are filled with inefficiencies, are over-designed, and do not include electronic controls. These applications such as automotive electrification, automotive infotainment, and power electronics across many industries are driving the need for new ways of thinking and new design flows. ANSYS 16.0 delivers! Continue reading

Magnetoelasticity: A 20-Year Journey from Cornell to Michigan Tech to ANSYS INC.

I was reminded of Professor Francis Moon, Joseph C. Ford Professor of Engineering Emeritus, when I visited Cornell University this summer for the 2014 Engineering Development Forum. You see, 20 years earlier I had just completed my PhD dissertation in the area of magnetoelastic buckling, a topic that was initiated by Professor Moon in 1968. His breakthrough research created immense interest around magnetoelasticity in the research community. Continue reading

Designing Motors with a Coupled Simulation Approach

Last year, the company I work for — CFX Berlin (an ANSYS channel partner) — was selected as runner-up in the ANSYS Hall of Fame competition. The application we submitted was about designing motors with a coupled simulation approach, based on work we performed with a customer. When ANSYS asked us to participate in a webinar on this topic, we were happy to share what we learned.

ANSYS Hall of Fame 2013 runner-up CFX Berlin

The company we supported was Anhaltische Elektromotorenwerk Dessau GmbH (AEM Dessau), an electrical motor factory in Germany. The business is shifting from traditional development processes to true simulation-based product development for rotating electrical machines. The integrated electromagnetics and fluid dynamics (CFD) software from ANSYS makes it possible to perform real multiphysics calculations for these machines.

I’ll give you a little background on this project. AEM Dessau has more than 60 years of experience in producing rotating electrical machines. The company produces user-friendly, innovative and safe products that meet the highest standards of quality and reliability.  It is not only a supplier but partners with their customers to help them compete in this market space.

Improving Productivity with New Features ANSYS 14.5 for Geometry and Meshing

Wednesday, December 05, 2012
4:00 pm EST, 9:00 pm GMT (REGISTER)

A typical simulation workflow requires reading geometry, cleaning it, creating a closed body, generating mesh and reviewing mesh quality. For having a hex dominant mesh, additional geometry decomposition steps may be required. This process can be tedious.

In ANSYS 14.5, there are host of new features in ANSYS DesignModeler (DM) and ANSYS Meshing (AM) that makes preprocessing faster, more efficient and hence resulting in improved productivity for CFD and Mechanical workflows. These enhancements include support of newer CAD releases, usability for DM and AM, improved performance while dealing with large sized CAD geometry and hex dominant mesh in AM. Continue reading

Curious About Making User Defined Functions in ANSYS Fluent?

Tuesday, September 4, 2012
9:00 am EDT, 1:00 pm GMT (REGISTER HERE)

ANSYS Fluent is a general CFD solver. To make it even more flexible you have the possibility to write your own functions to work together with the solver. Writing UDF:s can get very complicated and be as versatile as the applications themselves. This webinar aims at showing the basic process of writing and using an UDF. This will be done by showing how to define a profile, which is general and simple enough to be of use for any ANSYS Fluent user. In more detail the topics included will be:

  • Writing the C-code
  • Interpreting or Compiling the code
  • Hooking the code in the GUI
  • Running the simulation with a UDF
  • Questions and answers Continue reading
