How to ensure electric drives efficiency and cooling performance

0 (0) Electromagnetics PRESENTER:Ahmed Shoeb EXPERTISE:Electromagnetics Software:JMAG JMAG-Designer Ver. 23.0 was released on December 2023. JMAG has been developed to automate design. To this end, Ver. 23.0 has further improved functionality so that it can be used in all phases of design, from the initial design phase to detailed design. The processing efficiency of large-scale […]

0 (0) Electromagnetics PRESENTER:Nithara Narayanan & Supriya Singh EXPERTISE:Electromagnetics Software:JMAG In addition to the torque generated by the magnetic fields of magnets and rotating magnetic fields, Interior Permanent Magnet (IPM) motors harness reluctance torque, arising from the variance between d-axis and q-axis inductance. This unique feature empowers IPM motors with expansive operating capabilities and exceptional […]

3 (1) Electromagnetics PRESENTER:Ganesh & Vinaykumar EXPERTISE:Electromagnetics Software:JMAG An IPM motor can use both magnet torque and reluctance torque, so by appropriately choosing the current phase it is possible to improve efficiency over a broad spectrum of drive range. It is a motor type that is often used in equipment with a wide operational range, […]

Range Finder can be used to ensure that the established geometry required for optimization calculations is obtained while properly adjusting the dimensional range. […]

0 (0) Electromagnetics PRESENTER:Yves Thioliere EXPERTISE:Electromagnetics Software:JMAG In this presentation a workflow is presented for multi-objective, multi-constraint optimization calculations. A large design space is needed to be explored to reach an optimal solution. By means of design space exploration by simulation we first ensure that there are no broken geometries created and we can output […]

0 (0) Electromagnetics PRESENTER:Stephan Guenther EXPERTISE:Electromagnetics Software:JMAG The multi-objective optimization of electrical machines is an increasingly important topic within the design process due to the typically large number of objectives and constraints given by requirements. The design process developed by IAV deals with the efficient solution of these large-scale optimization problems based on a specific […]

0 (0) 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 […]

0 (0) 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 […]
