Mainly due to unstable price of the magnet raw material that is one of the main challenges for engineers to forecast the final cost of the wind turbine. This paper presents design of a direct drive switched reluctance generator (DDSRG) for wind turbine applications using Finite-Element Analysis (FEA) tools. The performance, weight, and cost of the proposed DDSRG is compared to a direct-drive permanent magnet generator (DDPMG). The FEA results demonstrate that for the same dimensions, the final cost of the proposed DDSRG is lower when compared to the conventional DDPMG for wind turbine applications. The main drawback of the DDSRG is that it has lower output power than DDPMG for the same dimensions. Also a DDSRG for the same output power as DDPMG has been designed in this paper.","PeriodicalId":6477,"journal":{"name":"2015 IEEE International Electric Machines & Drives Conference (IEMDC)","volume":"145 1","pages":"181-186"},"PeriodicalIF":0.0,"publicationDate":"2015-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74905699","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 method introduces \"Induced Voltage caused by Magnetic Saturation (IVMS)\". The IVMS is detected in the open phase of a Permanent Magnet Synchronous Motor (PMSM) driven by the block commutation. The commutating phases in this method are switched in accordance with the detected IVMS in the open phase. The detected IVMS is compared with the threshold voltage that was adjusted in advance. When the IVMS corresponds to the threshold voltage, the commutating phase is switched to the next phase. Therefore, the threshold voltages for the IVMS need to be correctly adjusted. However, several factors are involved in changing the threshold voltages, such as the motor characteristics, carrier frequency, and detection circuit. An automatic tuning technique for the threshold voltages of the IVMS-based position sensorless method is proposed in this paper. The principle for it and the experimental results are also presented.","PeriodicalId":6477,"journal":{"name":"2015 IEEE International Electric Machines & Drives Conference (IEMDC)","volume":"204 1","pages":"872-877"},"PeriodicalIF":0.0,"publicationDate":"2015-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74393779","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 proposed fault detection method has been developed through novel decomposition technique of sequential components of a five-phase electrical machine. Unlike conventional three phase machines, phase fault of five-phase machine shows different response under single phase fault, two adjacent phase fault, and two non-adjacent phase fault. A newly developed symmetrical component analysis is applied to identify those phase fault condition in five phase machines. The analysis has been further extended to detect the types of faults based on magnitude pattern of the fundamental frequencies of the symmetrical components in frequency domain. In this paper, open-phase fault detection analysis has been carried out through extensive simulation and experimental tests to validate the proposed method. A 5Kw dynamo system controlled by TI-DSP F28335 has been used.","PeriodicalId":6477,"journal":{"name":"2015 IEEE International Electric Machines & Drives Conference (IEMDC)","volume":"21 1","pages":"1405-1411"},"PeriodicalIF":0.0,"publicationDate":"2015-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80339747","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 PM motor has been designed and built to assess electromagnetic, fluid drag loss and dynamic performance. The design process utilised a theoretical equation for the fluid drag loss estimation which assumes a laminar flow. Assumption of the laminar flow has been validated by computational fluid dynamic analysis. A dummy motor was built and the fluid drag losses were measured for various speeds and temperatures. The test results show reasonable agreement with the theoretical calculation although the self-heating effect of the fluid made measurements at constant temperatures difficult.","PeriodicalId":6477,"journal":{"name":"2015 IEEE International Electric Machines & Drives Conference (IEMDC)","volume":"42 167 1","pages":"139-142"},"PeriodicalIF":0.0,"publicationDate":"2015-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83270511","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}

During this process adjustments of the model and the optimization algorithm will influence its success. Therefore, this paper introduces an analytical approach to verify the results achieved by an optimization process. This is done by pushing the observed mild hybrid electric vehicle (HEV) into the recuperation mode and the generator mode of the electrical machine. Now physical equations enable a verification approach to calculate the additional CO2 emission due to a variation of the efficiency of the electrical machine used in the power train of the HEV. The efficiency variation of the electrical machine is done on a measured efficiency map by increasing and reducing it by ±10% for the optimization process. The analytical verification approach should be easy to implement and enable to verify the results of the optimization process therefore a mid efficiency of the electrical machine is used. Compared to other approaches only changes of the CO2 emission are considered. This enables to model the internal combustion engine (ICE) in an easy way. Finally, the results of the analytical verification approach are compared to the results achieved by the optimization process.","PeriodicalId":6477,"journal":{"name":"2015 IEEE International Electric Machines & Drives Conference (IEMDC)","volume":"428 1","pages":"1494-1500"},"PeriodicalIF":0.0,"publicationDate":"2015-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75886342","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}

During the vehicle's normal operation, demagnetization can occur in the magnets due to temperature rise and high current loading, which could change the IPM's electrical and mechanical characteristic and the overall system performance significantly. To study these effects on the system level, in this paper, we propose a reduced order motor model based on FEA solution that takes into account the permanent magnet's temperature dependency, current loading and nonlinear saturation effects. The proposed model runs at circuit simulation speed which is suitable for system level simulation and while having the accuracy of FEA. Using this model, we are able to quantify the current consumption during a standard drive cycle simulation due to temperature and current loading variations.","PeriodicalId":6477,"journal":{"name":"2015 IEEE International Electric Machines & Drives Conference (IEMDC)","volume":"1 1","pages":"543-549"},"PeriodicalIF":0.0,"publicationDate":"2015-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89662266","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}
