The actuator must provide answers to the volume constraint and torque. This application is employed in land transport for aeronautical field. The axial flux motors become interesting when obtaining large surfaces of air-gap with the traditional machines is no possible. Indeed, surfaces of air-gap are more important in comparison with a radial flux machine, and, in a given volume, they allow to obtain a higher torque. After having shown the multi-air gap structure, we describe the design method from elementary cells. That's why two types the disc-type motor were selected. This paper clearly shows the efficient topology of a disc-type multi-air gap machine.","PeriodicalId":6309,"journal":{"name":"2012 XXth International Conference on Electrical Machines","volume":"4 1","pages":"647-652"},"PeriodicalIF":0.0,"publicationDate":"2012-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78443752","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 new design comes out as a result of a reconfiguration process of a real model by means of FEM-based analysis. The main transformation consists in replacement of the regular drum winding with a toroidal one, which allows a high flexibility in changing the number of pole pairs. The purpose is mainly to create the possibility of obtaining a superior torque capability by changing the synchronous speed. The primary study started with the laboratory experimental tests of the basic model followed by a simulation based on finite element method. Further, the drum winding has been replaced with a toroidal (ring) one designed for p = 1, p = 2 and p = 4. In this structure, new simulations have been run in order to make a proper comparison to the real model. The analysis tool used both magneto-dynamic and transient simulations.","PeriodicalId":6309,"journal":{"name":"2012 XXth International Conference on Electrical Machines","volume":"48 1","pages":"411-417"},"PeriodicalIF":0.0,"publicationDate":"2012-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75756586","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}

Unlike previous literature, expressions for torque interference caused by suspension force winding configurations and effects of d-axis flux on suspension forces are developed and presented. Furthermore, it is demonstrated that each rotor structure can be analyzed as an equivalent classical machine to allow for easy comparison.","PeriodicalId":6309,"journal":{"name":"2012 XXth International Conference on Electrical Machines","volume":"256 1","pages":"570-576"},"PeriodicalIF":0.0,"publicationDate":"2012-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73038945","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}

It is shown that the force density of a linear magnetic gear is affected by the required output stroke and gear ratio. A technique based on lumped parameter magnetic circuits is presented. It is employed for prediction of the flux density waveforms and the thrust force of the magnetic gear, which are in good agreement with those predicted by magnetostatic finite element analysis. A prototype 3.25:1 linear magnetic gear is described. It is shown that the force capability of the linear magnetic gear can be very sensitive to manufacturing tolerances, in particular those related to the spacing between the pole-piece rings.","PeriodicalId":6309,"journal":{"name":"2012 XXth International Conference on Electrical Machines","volume":"40 1","pages":"563-569"},"PeriodicalIF":0.0,"publicationDate":"2012-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74222393","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}

If so, thanks to wide ATP availability designers will have available an easy and user friendly tool for helping in their designs.

In performing this calculation, it is a common practice to apply the superposition principle, i.e. the power loss due to each single armature reaction field harmonic is computed and then the single loss contributions are summed to find the total losses. Such method would be correct if all stator harmonics produced rotor eddy currents with different frequency, but this is not generally the case. This paper investigates if and under what conditions the harmonic superposition principle can be applied without causing calculation errors. The investigation is extended to different kind of permanent-magnet machines, including surface-mounted, Halback and interior permanent magnet rotor topologies.","PeriodicalId":6309,"journal":{"name":"2012 XXth International Conference on Electrical Machines","volume":"90 1","pages":"1369-1373"},"PeriodicalIF":0.0,"publicationDate":"2012-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84559136","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}
