Our first paper extended Ruoho\u2019s work on harmonic field distributions to the reaction field of eddy currents within permanent magnets. The approach was based on the methods of the harmonic complex AC\u00a0calculation. In this paper, the models presented in our previous paper are further extended to allow 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 non-constant inductance.<\/jats:p>","DOI":"10.1007\/s00502-023-01148-y","type":"journal-article","created":{"date-parts":[[2023,8,4]],"date-time":"2023-08-04T12:02:10Z","timestamp":1691150530000},"page":"497-516","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Lumped model eddy current analysis of influence factors on PM segmentation effectiveness","Analyse von Einflussfaktoren auf PM-Segmentierungseffizienz anhand eines Modells mit konzentrierten Ersatzelementen"],"prefix":"10.1007","volume":"140","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":[[2023,8,4]]},"reference":[{"key":"1148_CR1","doi-asserted-by":"publisher","unstructured":"S.
