In the first paper, Ruoho\u2019s work on homogeneous materials was discussed. The distribution of fields has been expanded to include the reaction field of the eddy currents within the permanent magnets. This approach was based on the methods of the harmonic complex AC calculation. In the second paper, the models were expanded to enable a\u00a0harmonic calculation of eddy current losses in permanent magnets for homogeneous fields including the effects of eddy current losses in an adjacent ferromagnetic material, leakage flux factors, and source behavior. In this third and final publication, a\u00a0look at state-of-the-art analytical models will be taken. With regard to the results of the second publication of this series, it can be shown that established analytical models are insufficient when calculating inverter-related eddy current losses in permanent magnets of permanent magnet synchronous machines (PMSM). Furthermore, a\u00a0short introduction to eddy current loss mechanics in permanent magnets of PMSM will be given.<\/jats:p>","DOI":"10.1007\/s00502-024-01207-y","type":"journal-article","created":{"date-parts":[[2024,3,12]],"date-time":"2024-03-12T21:22:41Z","timestamp":1710278561000},"page":"145-154","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Why state-of-the-art analytical models for eddy current losses in PM of PMSM are insufficient for variable speed motors","Warum aktuelle analytische Berechnungsmodelle f\u00fcr die Berechnung von Wirbelstromverlusten in PM von PMSM bei Umrichterbetrieb unzureichend sind"],"prefix":"10.1007","volume":"141","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4252-9610","authenticated-orcid":false,"given":"Mike","family":"K\u00f6nigs","sequence":"first","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5104-1441","authenticated-orcid":false,"given":"Bernd","family":"L\u00f6hlein","sequence":"additional","affiliation":[]}],"member":"297","published-online":{"date-parts":[[2024,3,12]]},"reference":[{"issue":"10","key":"1207_CR1","doi-asserted-by":"publisher","first-page":"4756","DOI":"10.1109\/TMAG.2009.2024159","volume":"45","author":"K Yamazaki","year":"2009","unstructured":"Yamazaki K, Shina M, Kanou Y, Miwa M, Hagiwara J (2009) Effect of Eddy current loss reduction by segmentation of magnets in synchronous motors: difference between interior and surface types.
