Due to the rectangular slot geometry, stator teeth present a trapezoidal geometry with small tooth width close to the shaft, increasing as the diameter becomes larger. This fact introduces an uneven airgap flux distribution if a constant flux source, such as rectangular PM, is utilized to magnetize the machine. As a result, flux density over the stator tooth becomes irregular, inductance parameters are a function of the stator diameter and saliency varies according to machine load. All these effects degrade machine power capability for low and rated load. In this paper, a novel axial flux PM machine with tangential magnetization is presented. An analytic and numerical study is carried out to consider stator tooth geometry and its effect over machine saliency ratio.","PeriodicalId":416125,"journal":{"name":"2008 18th International Conference on Electrical Machines","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125347507","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In these cases, the usual T-equivalent circuit for stationary operation is no longer valid, but one coil of the machine has to be used as the smallest symmetry unit. Unsymmetrical windings may cause additional asynchronous and synchronous harmonic torques that might e.g. prevent the start-up. The new calculation method was verified by measurements of a large manufacturer of part winding motors where during start-up only a part of the stator winding - e.g. one of two parallel branches per phase - is connected to the mains. The calculation scheme leads to good results in the prediction of the start-up characteristic of such motors.","PeriodicalId":416125,"journal":{"name":"2008 18th International Conference on Electrical Machines","volume":"80 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121194301","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}

A particularity of this actuator is also the friction of the movable parts on the fixed parts. It allows to use very small dimensions on the active parts and so to increase the performances.

The need for equivalent circuits rises from practical applications. Accurate models are needed for control design and power system analysis. The research was conducted using the 2D finite element analysis and the differential evolution algorithm. As an input to the synchronous machine, a pulse is used within the FEA at the rated operation point. The pulse was applied to the line-to-line voltage of the stator. Using the pulse input, the harmonic excitation can be avoided. The input in addition to the response provided the numerical data for estimation. On one hand, theoretical equations based on the equivalent circuits can be derived. The theoretical model was fitted in the numerical data using the least-squares cost formulation, and the DE algorithm was used to minimize the cost function. Results for a 6-pole, 12.5 MW synchronous machine are presented.","PeriodicalId":416125,"journal":{"name":"2008 18th International Conference on Electrical Machines","volume":"110 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133697139","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}
