The complete model comprises two sub-models that separately calculate the ac losses contributed by the in-slot and end-winding portions. 3D finite element analysis and experimental tests are conducted to demonstrate the usefulness of the model. The results also confirm the vulnerability of form-wound windings to steep increases in the winding ac resistance as the excitation frequency increases. The model is subsequently used to investigate the impact of key machine parameters on the winding ac losses, including the excitation frequency, phase arrangement, conductor thickness, and PWM switching frequency.","PeriodicalId":6477,"journal":{"name":"2015 IEEE International Electric Machines & Drives Conference (IEMDC)","volume":"9 1","pages":"1131-1137"},"PeriodicalIF":0.0,"publicationDate":"2015-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89466003","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 machine is designed for a variable speed direct driven vertical axis wind turbine. One of the optimized parameters in the design procedure is the cost of active material. High efficiency, high torque density and easy scalability are some attributes that makes the surface mounted PM machines very attractive solutions for wind power application. However, the cost of the active material, especially permanent magnets, has to be minimized. The results presented here shows low harmonic contents of the air gap flux density and the induced voltage. Hence, the cogging torque is very low, which together with low radial forces indicates a low magnetic noise as well.","PeriodicalId":6477,"journal":{"name":"2015 IEEE International Electric Machines & Drives Conference (IEMDC)","volume":"43 1","pages":"48-52"},"PeriodicalIF":0.0,"publicationDate":"2015-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89903276","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 abundance of space harmonics in the air gap flux have rendered FSCW configurations unsuitable for induction motors. This paper proposes the use of a multi-layer FSCW wound around two layers of stator slots that eliminates sub (a fraction of fundamental) and higher order space harmonics and provides a non-overlapping winding arrangement. This winding configuration has several advantages like high torque density, shorter end-winding length and easier manufacturability for outer rotor squirrel cage induction motors for pumps, fans and in-wheel hub drives.

Flux switching, modulated pole and surface mounted magnet machines are individually modelled and optimized to react the force of the engine with minimum magnet mass. The mass of magnet used in each design is found to be heavily dependent on the copper loading in the machine and the flux produced at no load. The modulate pole or transverse flux machine, which in other applications gives an extremely efficient use of magnet, is here shown to be more effective than conventional machines but less effective than the flux switching machine.","PeriodicalId":6477,"journal":{"name":"2015 IEEE International Electric Machines & Drives Conference (IEMDC)","volume":"1978 1","pages":"642-648"},"PeriodicalIF":0.0,"publicationDate":"2015-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86588092","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 protection is often performed using inverter output chokes with laminated cores to smooth the output current waveform and limit charging currents. As cable and choke reactor form an LC-circuit, they do support oscillations of current and voltage especially at the inverter terminal with unpredictable effect on the core loss of the output choke. The research presented in this paper is an attempt to quantify the core loss in laminated iron cores for highly distorted current waveforms. In a laboratory setup, a scale model of a choke inductor is integrated into an LC-circuit and supplied with inverter feed in order to imitate the current signal found in real world applications. The measured current waveforms are fed into a loss model based on a magnetic equivalent circuit and the equivalent elliptical loop model to compare simulated losses with the measured values. A good agreement is achieved.","PeriodicalId":6477,"journal":{"name":"2015 IEEE International Electric Machines & Drives Conference (IEMDC)","volume":"63 1","pages":"1260-1264"},"PeriodicalIF":0.0,"publicationDate":"2015-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78690029","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 the high material cost of PM machine, there was a continuous effort to reduce the amount of permanent magnets (PM) in manufacturing an electric machine. PMa-SynRM has reduced great amount of PM usage by hybridizing the architectures between Synchronous Reluctance Motor and Permanent Magnet Motor. To further reduce the PM usage and to further increase of torque density, design of PMa-SynRM has been investigated through external rotor architecture. With best of author's knowledge, external rotor has not been properly researched even with great advantage and design flexibility with PMa-SynRM architecture. Analytical comparison between two different types of motor (internal and external) has been investigated to prove the superior design flexibility and performance of proposed method. Performance characteristics such as average torque developed and variation of torque with respect to variation in speed have been analyzed in finite element atmosphere (FEA) to validate the proposed design. A lower torque ripple model with distributed winding structure has been modeled and its FEA simulation results for developed torque have been compared with the concentrated type external rotor PMa-SynRM model.","PeriodicalId":6477,"journal":{"name":"2015 IEEE International Electric Machines & Drives Conference (IEMDC)","volume":"33 1","pages":"220-226"},"PeriodicalIF":0.0,"publicationDate":"2015-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88520827","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}

Therefore 3-D FEM is not useful for an optimization tool.

Thereby 36 different motor designs (with different pole pitch, diameter and tooth geometry) and 2 different current-values (one causes strong saturation) are used to evaluate the accuracy and limits of those methods. The deviations of magnetic flux and torque from 3-D FEM results (ANSYS® Maxwell®) are discussed based on statistical probability distributions. The results will show that the equivalent network and the 2-D FEM are not useful for all of the investigated motor designs.","PeriodicalId":6477,"journal":{"name":"2015 IEEE International Electric Machines & Drives Conference (IEMDC)","volume":"125 ","pages":"1158-1164"},"PeriodicalIF":0.0,"publicationDate":"2015-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91464675","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}
