As you can imagine, there are many conversations at ANSYS centered around the simulation industry and current engineering trends. Sometimes during the conversations with my colleagues that handle the microwave and RF communication and signal and power integrity sectors of our business, I get the feeling that electromechanical design and power electronics is boring. Why do we want to talk about simulation of devices that have been around for a century like electric motors and transformers? Continue reading
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.
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.

Ask the Expert – Benefiting from Cyclic Symmetry in ANSYS Mechanical and Mechanical APDL 14.0
Wednesday, October 10, 2012
4:00 pm EDT, 8:00 pm GMT (REGISTER)
A geometry is called cyclic symmetrical when a structure is rotationally symmetrical about one axis so that the full structure can be produced by copying the cyclic portion. Fan wheels, spur gears, and turbine blades are all examples of structures that exhibit cyclic symmetry. For example, a 36-blade turbine wheel assembly may have 36 repeating 10 degree segments. ANSYS Mechanical and Mechanical APDL can use cyclic symmetry to more efficiently solve static, modal, harmonic, and buckling analysis. It is only necessary to build and mesh one of the repeating segments, so the efficiency gain can be significant. Mechanical and MAPDL will solve for the behavior of that sector and use that single-sector response to construct the response for the full component. This ANSYS webinar will explain how cyclic symmetry models are created and analyzed using ANSYS Mechanical and Mechanical APDL 14.0. Continue reading
We have a plethora of ANSYS webinars, face-to-face seminars and workshops this week. For instance, if you’re in or around Washington, DC for the NAFEMS North America Conference, we’d love to have you stop by our booth and say hello.
Below you’ll find a more comprehensive listing of ANSYS webinars and seminars. Make sure you register today for the events you’d like to attend. Continue reading
It’s my pleasure to announce that ANSYS is collaborating with the University of Wisconsin-Milwaukee and IEEE Milwaukee Power Electronics Chapter to present the “Microgrid Control for Power Systems Applications” course being held in Milwaukee, Wis., on Sept. 13-14. Upon on the completion of the course, the participants will be awarded 1.6 Continuing Education Units (CEUs) through IEEE, which is the world’s largest professional association of electrical and electronic engineers.
This advanced course, taught by leading international experts, will equip attendees with the theory and advanced simulation techniques required to effectively design power electronics and associated control systems. The emphasis will be on timely topics related to micro-grids that incorporate distributed energy generation facilities and can operate in grid-tie and island mode. Continue reading
