The strategic use of oriented steel in a segmented stator AC electric machine can potentially improve performance by reducing core losses compared to machines using non-oriented steel. However, the introduction of cut-edges and the stress on individual segments due to segmented stator construction may lead to unintended consequences. Despite various efforts to evaluate the impact of cut-edges or oriented steel on core losses in segmented stators, the literature lacks an analysis of the loss separation between tooth and back-iron components using manufactured stators. This gap hinders a comprehensive understanding of the true impact of using oriented steel in segmented stator construction for core loss improvement. In this study, we calculate the loss of each tooth and back-iron segment by conducting experiments with three different electromagnetic devices, specifically H-shaped steel laminations. By comparing the results from three manufactured stators, we clarify the influence of oriented steel in relation to segmented stator construction.

In this session, you will learn more about:

• Experimental Evaluation of impact of cut edges on the machine performance manufactured using Oriented Steel Segmented Stator.
• Separation of Tooth and back iron core losses to find the individual impact and the dominating player.
• Evaluation expanded to all saturation levels the machine experiences that captures real life application.
