Electromagnetics PRESENTER:Bernd Cebulski EXPERTISE:Electromagnetics Software:JMAG Modern electric motors for automotive EV applications have to match a number of requirements with high efficiency and low cost still being the most important. Apart from the general design task, the engineer has to handle many additional challenges for specific problems and issues. When it comes to accuracy comparison […]
Electromagnetics PRESENTER:Professor Z.Q Zhu EXPERTISE:Electromagnetics Software:JMAG Permanent magnet (PM) machines, particularly interior permanent magnet (IPM) machines, have been widely used for many applications due to high torque density, high efficiency and relatively low PM usage. This presentation overviews IPM machines for electric vehicles, with reference to novel magnetic-field-shifting techniques for enhancing the torque in a […]
Electromagnetics PRESENTER:Bharadwaj Raghuraman EXPERTISE:Electromagnetics Software:JMAG This presentation demonstrates the electrical machine design process using both the parametric and topology optimization methods for e-mobility application. The parametric optimization is used toward meeting performance requirements while keeping the product sustainability and efficiency targets, however, topology optimization is mainly employed to address NVH aspects of the designed electrical […]
Electromagnetics PRESENTER:Yves Thioliere & Shafigh Nategh EXPERTISE:Electromagnetics Software:JMAG Multi-objective multi-constraint optimization is required for the design of high performances electrical appliances because of their need to satisfy a multitude of requirements. Optimization issues such as these perform searches within small and complex regions (design spaces that satisfy all constraints). Multipoint searches such as genetic algorithms […]
