These losses, referred to as commutation losses, can be substantial in large propulsion motors. This paper presents a further refinement in the analytical model derived and presented in an earlier paper. The improved model is able to account for the space harmonic effect of the stator resultant magnetomotive force (MMF) on commutation losses and consequently can lead to a more accurate prediction of the commutation loss. The model was verified by comparing its results with those obtained using the finite element method at several operating speeds and current levels. The results show good improvement (an average value of 6.8% for the total losses) compared with the earlier model (an average value of 11.7%).","PeriodicalId":176640,"journal":{"name":"1997 IEEE International Electric Machines and Drives Conference Record","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1998-10-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131025171","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The proposed PSPICE net-list structured approach allows easy adding or deleting of harmonic contribution to the drive motor dynamics. Variety of transient behavior cases, such as starting, speed reversal, frequency perturbation, are investigated.

The results, both experimental and simulated, show that for a modulation index above 0.45 the direct-indirect method progressively gives lesser current ripple and becomes almost half at around a modulation index of 1.
