Therefore, on-line diagnosis of incipient stator winding short-circuit faults plays an important role contributing to the safe operation of PMSMs. However, the efficacy of known diagnostic methods varies with the types of stator winding configurations in PMSMs. This paper compares the effectiveness of diagnosis of stator winding short-circuit faults in series and parallel winding connections of PMSMs, with the same interior permanent-magnet rotor configuration. Two existing diagnostic methods have been applied to detect the severity of stator short-circuit faults happening in both series and parallel winding connection in PMSMs. Simulation analysis has been carried out in ANSYS Maxwell to compare the severity of magnetic saturation caused by equivalent short-circuit fault in series and parallel winding connected PMSMs. Experimental results lead to the conclusion that PMSMs with parallel winding connections can mask the influence of such stator short-circuit faults under certain circumstances, and thus it is more challenging to detect such incipient faults in parallel-winding-connected PMSM in comparison with series-winding-connected PMSMs.","PeriodicalId":6477,"journal":{"name":"2015 IEEE International Electric Machines & Drives Conference (IEMDC)","volume":"2 1","pages":"1387-1393"},"PeriodicalIF":0.0,"publicationDate":"2015-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87133338","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}

This tends to increase the package size of general engine generators. In this paper, we are able to achieve miniaturization and high output power of the generator by adopting an axial-gap structure through using ferrite permanent magnets. At the same time, the package size is reduced dramatically by integrating the axial-gap generator into the engine. This paper also discusses methods for reducing the eddy current losses that occur in the windings due to the open-slot structure of the stator core and occur in the rotor support component. By using results from three-dimensional finite element analysis, we show that the eddy current loss that occurs in the windings is reduced by using appropriate methods to wind the coils with rectangular wires. In addition, the eddy current loss that occurs in the rotor support component is decreased by appropriately selecting the material and changing the shape of the component. Experimental results show that the studied structure is effective for realizing miniaturization and high output power of the generator, as well as for decreasing the package size of the engine generator.","PeriodicalId":6477,"journal":{"name":"2015 IEEE International Electric Machines & Drives Conference (IEMDC)","volume":"1 1","pages":"300-307"},"PeriodicalIF":0.0,"publicationDate":"2015-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91004181","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}

However, the PM usage volume of PS machines is relatively large and the cost is high, which is undesirable for cost sensitive applications. In this paper, a PS machine employing ferrite PMs is presented, which can take the advantage of large space for PMs in PS machines as well as balance the performance and cost. The electromagnetic characteristics of an optimized ferrite PS machine and an optimized NdFeB PS machine are compared, together with a classic Prius2010 interior-PM (IPM) machine as a baseline for comparison. In addition, the economic issues are considered as well. The predicted results reveal that the NdFeB PS machine can produce much higher torque density but is more expensive than the Prius2010 IPM machine, whilst the ferrite PS machine can significantly reduce the cost and still exhibit comparable performance as the Prius2010 IPM machine and the highest torque per cost. The demagnetization behavior of ferrite PS machine is evaluated and a method to improve the demagnetization withstand capability is proposed. A pair of scaled prototypes are manufactured to validate the finite element predictions.","PeriodicalId":6477,"journal":{"name":"2015 IEEE International Electric Machines & Drives Conference (IEMDC)","volume":"16 1","pages":"461-467"},"PeriodicalIF":0.0,"publicationDate":"2015-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73715837","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}

Nowadays technological advances such as superconducting electromagnets (with very low power consumption for higher overall efficiency), power electronics (to enable harvesting and processing of current intensive DC power for any application), and powerful multiphysics simulation software, call for a reassessment of this power generation method. The aim of this paper is to deliver a realistic analysis of the competitiveness of MHDG as well as the possibilities offered by design variables to improve its attributes. Finite element analysis offers an improved understanding of field and flow distribution as well as the power density generated within the fluid channel. Analytical energy efficiency determination is completed for two different fluids as well as a sensitivity study of influential design factors. Furthermore a power output/cost comparison between MHD-systems operating with combustion gasses and liquid copper is carried out to offer a complete assessment of MHDG.","PeriodicalId":6477,"journal":{"name":"2015 IEEE International Electric Machines & Drives Conference (IEMDC)","volume":"55 1","pages":"1197-1201"},"PeriodicalIF":0.0,"publicationDate":"2015-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73569446","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}
