Aix en Provence (France) – July 6th, 2020


In the frame of our distribution agreement for MSC Cradle CFD for the French and German markets, Powersys and MSC Software Corporation are glad to announce the launch of two webinars that will demonstrate a coupled magnetic field and thermofluid analysis using JMAG and MSC Cradle.


Solve the problem of rising temperatures is a critical issue when trying to achieve an improvement in an electric motor’s efficiency and output. In order to do that it is important to investigate a magnetic design that reduces the losses themselves because they are a source of heat, but it is also important to study a thermal design that improves heat dissipation and does not let the temperature rise. Copper/aluminium losses in the coils and iron losses in the core are the dominant heat sources, so this analysis mainly evaluates the effects of this heat. Changes in the magnet’s properties due to temperature are large and its heat resistance is low, so it is necessary to design while paying careful attention to rising temperatures during operation. During operation, rated evaluations with a continuously operated constant load are run until a thermal balanced state has been reached. In addition, thermal transient evaluations, that add a thermal cycle with an intermittently operated electrical overload, are performed. To carry out an accurate thermal design, it is necessary to understand the heat generation amount and location correctly. Therefore, it would be advantageous to calculate the losses in a magnetic field analysis simulation using the finite element method (FEM), and from there to carry out a thermal FEM analysis using the resulting loss distribution. On July 7th and 8th, Powersys will run respectively a webinar in French and in German/English to show and explain how to do an electric machine cooling analysis using a coupled Magnetic Field software, JMAG and a Thermo-fluid software, MSC Cradle.
