This article proposes a diagnosis method of inter-turn short circuit fault for PMSMs based on the duration of the space vectors via finite control set model predictive control (FCS-MPC) strategy. The method is performed by evaluating whether the duration of different space vectors has changed or not, following that, the specific changing space vectors are used to locate the phase sequence where the fault happened. Furthermore, this study proposes that the observed space vector distribution characteristics can be qualitatively explained by closed-loop control for the suppression of inter-turn short circuit fault. The prominent advantage of the proposed method is that no additional sensors are necessary, the little burden is added to the microcontroller and it also works well for variable frequency control. The results of the simulation verify the effectiveness of the proposed diagnosis method to detect and locate inter-turn short circuit faults.","PeriodicalId":45126,"journal":{"name":"Asia-Pacific Journal-Japan Focus","volume":"55 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2022-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85018490","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}

For the motor winding coefficient, it is firstly proposed to put auxiliary windings with different turns in the same direction in the motor armature teeth to improve the fundamental winding coefficient and weaken the 5th and 7th harmonic winding coefficients. On this basis, the cogging torque expression obtained by the energy method is used to analyze the auxiliary tooth tip angle by the Fourier decomposition method. The correctness of the theoretical derivation of the winding coefficient is verified by the air-gap flux density and no-load back EMF simulated by the finite element. Finally, the cogging torque of the motor and the equal-tooth motor structure are simulated and compared, and the results show that the effect of the motor to weaken the cogging torque is remarkable.","PeriodicalId":45126,"journal":{"name":"Asia-Pacific Journal-Japan Focus","volume":"26 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2022-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91125759","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}

So far, analytical approaches upon calculating airgap permeance have been adopted in most existing research work, while corresponding simulation-based tools have rarely been reported. In this paper, a new concept of airgap permeance calculation developed from numerical finite element tools is presented. Based on similarity of magnetic field and electric field, the airgap permeance distribution of electrical machines with various topologies can be predicted rapidly through finite element analysis (FEA) in electrostatic field. The FEA-based airgap permeance distribution can be regarded as an effective approach to validate corresponding results calculated from complex mathematical derivation. Furthermore, the characteristics of working airgap flux density harmonics introduced by magnetomotive force (MMF) of stator or rotor could be more intuitively investigated. Based on case studies of several typical machine topologies, the proposed FEA-based method will be proved of featuring wide feasibility, i.e., capable of covering stator slotting effect, rotor saliency as well as dual side saliency effect. Finally, the reasonability of the permeance calculation method is verified based on a further proposed homopolar topology within electromagnetic FEA.","PeriodicalId":45126,"journal":{"name":"Asia-Pacific Journal-Japan Focus","volume":"153 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2022-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74911626","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}
