This paper shows how optimization methods can be used to find an optimal design of tooth concentrated winding rotating field (CWRF) machines. The machine is considered as optimal if its MMF-harmonic distribution is made in such a way that unwanted effects, like noise, vibration, etc. are minimized. The paper suggests a way how to compute the MMF-harmonics as a function of design parameters, setting up an objective function and applying optimization algorithms on it.","PeriodicalId":101507,"journal":{"name":"2011 International Conference on Electrical Machines and Systems","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133789973","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}

In this paper, a dynamic equivalent core losses resistance is applied to count the core losses in the d- and q-equivalent circuit, which includes the copper losses and the core losses.

Increasing iron core length properly can raise motor efficiency and power factor, but it will reduce locked-rotor torque ratio and breakdown torque ratio.
