ANSYS Maxwell 18 – Conquer the New Demands of Electromechanical Design and Power Electronics

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

10x Faster Transient Electromagnetic Field Simulation

“I feel the need. The need for speed!” is a famous line from the movie Top Gun. Designers of electric motors, power transformers, planar transformers, and actuators — or anyone that regularly runs transient electromagnetic field simulations — can relate to that phrase. Transient electromagnetic field simulation is a powerful, accurate method to solve EM problems in the time domain, but the process is painfully slow even with today’s fastest computers. Thus, EM transient simulations often are relegated to the verification stage rather than the design stage of the device. With ANSYS Maxwell in ANSYS 17.0, you can now channel your inner Tom Cruise — ANSYS delivers on your need for speed! Continue reading

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 “Good old designs” of power systems and electrical machines using a build-and-test methodology are out of date.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

The State of the Art for Electric Motor Design

Have you noticed that electric machines are everywhere these days? They are present in industrial equipment, cars, planes, household appliances, computers, mobile devices and more. The applications for both large and small motors are just exploding. Power transfer technologies in airplanes, such as the central hydraulic system and flight control actuation, are being replaced with electric motors. Electric and hybrid electric vehicles are powered by electric motors. When you put your phone on vibrate, the pulsation is created by an electric motor! The increased use of electric machines is driven by the global demand for more-automated and power-efficient products. The key is to find a better process to take an electric motor design from start to end. Continue reading

Electric Machine Design Methodology

In 2009, the University of Wisconsin-Milwaukee, with full support from ANSYS, deployed an initiative to the region’s industrial community by launching the ANSYS Institute for Industrial Innovation (AI3). Recently, ANSYS and the university launched a video about common interests and partnership activities that tells the story behind the institute.

As you heard in the video, the institute at UWM is a portal for industry to engage with academia to foster economic growth and development of regional industries and educational institutions, leveraging world-class CAE capabilities including CAD, FEA and system simulation platforms. AI3’s framework provides an infrastructure that spans the product development cycle from concept to functional prototype. Continue reading

Microgrid Control for Power Systems Applications Course (1.6 CEUs)

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
