The output equation has two terms which are magnetic torque and reluctance torque. The magnetic torque is related to the electric-and magnetic-loading but reluctance torque is related to one more variable which is the difference of the d-and q-axis inductance. Therefore it is very important to calculate or estimate the d- and q-axis inductance in the design procedure. In this paper, we proposed the inductance calculation method by relative permeance. The result is reasonable to the initial design.","PeriodicalId":148739,"journal":{"name":"Digests of the 2010 14th Biennial IEEE Conference on Electromagnetic Field Computation","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129642801","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}

Gyroelectric medium is assumed to be bounded by isotropic media in the upper and lower sides. Transmission and reflection coefficients for the two-layered medium used in the DGFs are expressed in terms of half space transmission and reflection coefficients using the matrix method with the application of boundary conditions. This drastically reduced the complexity of the problem for the two-layered structure. The results presented here can be used for radiation or scattering problems in the presence of a layered media involving complex medium such as gyroelectric.","PeriodicalId":148739,"journal":{"name":"Digests of the 2010 14th Biennial IEEE Conference on Electromagnetic Field Computation","volume":"79 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124887937","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 magnetic suspension is assured by the repulsion between two arrangements of permanent magnets located both on toroidal shaped stator and rotor.

The presence of eddy currents due to the relative motion between the rotor magnets and the conductive sheet allows overcoming the intrinsic instability of the system. The dependence of the stabilizing force on the angular velocity will be determined as well as the levitation force, the magnetic drag force and the power dissipated in the conductor sheet by the stabilizing eddy currents.","PeriodicalId":148739,"journal":{"name":"Digests of the 2010 14th Biennial IEEE Conference on Electromagnetic Field Computation","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130957374","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}
