To check the generality of the developed model, two different types of commonly employed interior permanent magnet machines are considered. 2D finite-element analysis was used to benchmark the results from the analytical model. The proposed model can be directly used to evaluate the eddy current magnet loss for magnet segmentation in the circumferential direction. The influence of air-gap length, frequency of carrier harmonic, reaction field and non-linearity of iron due to saturation on the magnet loss have been studied in detail and the results are presented. The effect of axial segmentation has been considered by incorporating an end-effect factor in the analytical model. The results from analytical and 2D finite-element analyses are found to be in concurrence.","PeriodicalId":6477,"journal":{"name":"2015 IEEE International Electric Machines & Drives Conference (IEMDC)","volume":"12 1","pages":"1096-1102"},"PeriodicalIF":0.0,"publicationDate":"2015-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85619165","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 continuously varying wind speed causes instabilities in the output power of the WECS. The use of FESS improves the dynamic response of the system and smoothes the output power of the WECS and during variable wind speeds. A DFIM-based FESS is proposed in this study which works on the cascaded black-box optimization technique based proportional-integral (PI) controller. The PI controllers are used to control the insulated gate bipolar transistor (IGBT) switches of the frequency converter. In-depth modeling and control strategy of the system under study is presented. The effectiveness of the proposed system is tested under real-time wind speed data. The validity of the system is verified by the simulation results which are carried out using PSCAD/EMTDC.","PeriodicalId":6477,"journal":{"name":"2015 IEEE International Electric Machines & Drives Conference (IEMDC)","volume":"1 1","pages":"1545-1549"},"PeriodicalIF":0.0,"publicationDate":"2015-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91546143","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}

Due to IPM's rotor saliency, the traditional back electromotive force (back-emf) model for surface-mount permanent motors (SPM) cannot be used in IPM observers directly. In order to address this problem, the extended electromotive force (EEMF) model is adopted for observer design. Unlike many other EEMF model based SMOs, the phase delay mitigation algorithm (PDMA) integrated in the proposed observer significantly reduces steady-state estimation error while maintaining low-pass filter's dynamic performance. The simple structure makes the proposed observer an ideal candidate for cost-sensitive applications which guarantees satisfactory performance and efficiency. Theoretical analysis, simulation and experimental results are provided to validate the fidelity of the proposed SMO.","PeriodicalId":6477,"journal":{"name":"2015 IEEE International Electric Machines & Drives Conference (IEMDC)","volume":"8 1","pages":"846-852"},"PeriodicalIF":0.0,"publicationDate":"2015-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78908678","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 SynRM stator made of silicon steel, M36, 0.35 mm thickness is used. The machine was driven from a two and three level inverters and the current waveforms where used in the finite element model so as to capture the flux densities. The SynRM stator was then excited by these flux density waveforms obtained from the FE model. Tests were conducted at 30 Hz, 60 Hz and 180 Hz and there was an approximate 6 % reduction in core losses at 180 Hz under a three level inverter drive. The reduction in core losses were significant on the stator tooth than on the stator yoke.

For those BLDC motors in application, rotor faults account for most of the faults in BLDC motors. Static eccentricity and dynamic eccentricity are two of the main faults in the rotor of BLDC motor. In this paper, an improved method detecting static eccentricity is proposed based on the comparison between the positive sequence current and negative sequence current. Comparing to the traditional method which only focuses on the change of the negative sequence of fundamental frequency current, the method proposed in this paper could be more reliable since the positive sequence current and harmonics current are considered as well. A BLDC motor with static eccentricity in AHU (air handler unit) will be tested. The effectiveness and availability are verified in both simulation and experiment results.","PeriodicalId":6477,"journal":{"name":"2015 IEEE International Electric Machines & Drives Conference (IEMDC)","volume":"71 1","pages":"1473-1476"},"PeriodicalIF":0.0,"publicationDate":"2015-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88486683","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}

Torque ripples are obtained analytically using the Fourier coefficients of the flux linkages, and justified by comparing the results with FEA torque. With a linear flux model in current, the ripple components are expressed explicitly in current and high order saliency. Through simulations, it is demonstrated that the ripple increases as the d-axis current increases negatively along a constant torque line.","PeriodicalId":6477,"journal":{"name":"2015 IEEE International Electric Machines & Drives Conference (IEMDC)","volume":"236 1","pages":"127-132"},"PeriodicalIF":0.0,"publicationDate":"2015-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82741242","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 conventional six slots four poles topology suffers from asymmetrical flux linkage and severely unbalanced back-EMF, which makes it unfeasible. The proposed dual-stator structure utilizes windings in the second stator to produce a corresponding flux linkage that cancels the even order harmonic components in the first stator winding. The resulting flux linkage, back-EMF have no even order harmonics and are almost sinusoidal waveforms.
