Electrical machines are often simulated with symmetry sectors and periodicity conditions. This speeds up things a lot, but occasionally leads to weirdness.
What are Skin and Proximity Effect, or Circulating Currents
Skin and proximity effect can dramatically increase the losses in your electromagnetic device, as can circulating currents. Read here to learn about them!
Egear and Quantum Electric – Motor News from Finland!
Two new electric motor inventions from Finland. In a way, both are aimed at increasing the operating range of the motor. Read here to learn more!
Last Week’s FEA Tonight with Antti
Elsewhere in FEAsphere: failure modes, and how and why they are indeed uncertain. Plus stochastics in buckling, and some collaboration in the making.
Determining and Quantifying Sources of Uncertainty
Uncertainty quantification requires determining the sources of uncertainty, such as deviations in the product dimensions. Here’s how to do it.
Linear Buckling – Don’t Miss Out!
Linear buckling – so hot right now! Check out my brief outsider’s overview, and join the discussion with proper specialists!
What’s Troubling Engineers – Future Posts!
Conclusion of the Electromechanics Survey. Common issues identified for the people on this awesome field – future posts will address the key problems.
Frequency Response Analysis – When Motors Explode
Frequency response analysis is used to analyze how a system reacts to a specific excitation. Or, as I like to put it, when things explode.
Reverse Engineering the Ansys TDM
The TDM method by Ansys is reported to speed-up time-stepping computations by up to 6000 %. Read my idea on how it might work.
