Efficiency and loss calculation of Rail and Emobility Traction Motor

Electrification has now extended from Rail to Marine and Automotive industries. Additionally, electrified aerospace has shown the potential to be a trend in the near future. Different market segments however have different requirements leading to the need for the development of customized tools enabling traction motor designers to offer the best solutions to the customers. Automotive industry despite Rail and Marine has not yet come to standard traction motor designs. That is why different solutions and designs are being used by different OEMs. Maybe in future by more standardization of products, the demands on the tools will be flattened.
But, in the meanwhile all the alternatives are on the table and this is the designer job to pick the most suitable topology and optimized design based on the specific customer requirements. Consequently, the need for tools providing a high level of customization has raised and it is expected to further increase at least in the near future. JMAG as a strong electromagnetic tool with a high level of flexibility as well as advanced built-in modules that can be used for detailed calculation of motor parameters and performances has the potential to be integrated in the design and optimization process of traction motor, especially for e-mobility applications.
In this presentation, some of the key JMAG functions and their applicability together with some practical examples will be reviewed.
