A novel design of a magnetizing test fixture based on an electromagnetic Halbach array is used to perform measurements on a non oriented silicon steel sample of M36G29 at three different frequencies of interest to the industry 60 Hz, 400 Hz, and 1 kHz. The experimental results are fed to three types of electrical machine models, 2-pole induction machine (IM), 6-4 switched reluctance motor (SRM), and 2-pole brushless DC machine (BLDC) to investigate the effect of reversal of the rotating field direction on the delivered core loss in the stator. Results reveal that the IM experiences the highest effect of field reversing followed by the BLDCM, and then the SRM which is the least affected.","PeriodicalId":199452,"journal":{"name":"2013 International Electric Machines & Drives Conference","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130894666","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}

In the future transport area, electric vehicles are considered as replacement of oil-powered internal combustion engine driven vehicles, especially for the CO2 reduction and alternative energy perspective. However, electric vehicle requires several key issues resolved in view of the heavy weight, bulky volume, and limited driving distance. In this paper, the innovative on-road dynamic wireless charging technology for electric vehicle, called OLEV, is introduced. The electric vehicle charging technology can be classified as conductive or wireless, stationary or dynamic, and slow or fast. The fast charging in the range of 100 kW of power capacity and wireless dynamic charging concept are described. Also the design concept, system architecture and development process of optimizing the magnetic flux field for the higher power transfer efficiency are described in this paper. The dynamic charging technology is also compared with the stationary conductive charging for electric vehicles, in view of its development concept and status, and practical feasibility of the innovative technology.","PeriodicalId":199452,"journal":{"name":"2013 International Electric Machines & Drives Conference","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129694402","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, besides potential torque ripple mainly loud acoustic noise often makes industry go the conventional way. Vibration mode 0 can often be the most prominent noise source in larger sized SRM applications as for electric vehicles. This paper presents a control strategy to reduce this particular vibration mode. Because mode 0 is excited by all phases together the direct instantaneous torque control approach has been modified to regulate the phases' radial forces to achieve smooth overall radial force. It was found that it is possible to reduce mode 0 excitation effectively compared to standard control strategies such as, for instance, current hysteresis control. Controlling radial force smoothly can come along with mentionable torque ripple. Although, some operating points showed that further improvements on the employed force sharing algorithm can potentially extend the operating region which is characterized by both: smooth overall force and torque. Simulations prove that mode 0 vibration can be reduced or even be eliminated by means of control, leaving only the other occurring vibration modes to be attenuated (e.g. by machine design or notch-filtering the force reference) to develop a low noise switched reluctance drive.","PeriodicalId":199452,"journal":{"name":"2013 International Electric Machines & Drives Conference","volume":"40 4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132677257","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}

According to the pump and fan affinity laws decreasing the speed of the load can reduce the power consumption on the load significantly. Therefore, variable speed drive offers reduction in energy consumption of the induction motor driving these types of loads. As an alternative, permanent magnet synchronous machines can be used for this application to get the benefit of higher efficiency. In this paper, the performance of a permanent magnet assisted synchronous reluctance machine (PMa-SynRM) is studied for driving fan type load. The effect of using different amount of the permanent magnet in this machine is studied using experimental results. In addition, the performance of the PMa-SynRM is compared with a standard general purpose induction machine for the same loading condition. This paper presents the comparison of the energy consumption and performance of the machines under fan load operating on certain typical duty cycles.","PeriodicalId":199452,"journal":{"name":"2013 International Electric Machines & Drives Conference","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114378325","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}

By hybridization of the storage, adding double layer capacitors, the battery can be relieved from the stress of peak power and even downsized to meet only energy demands instead of power demands. Thus, the storage weight and losses can be significantly reduced. An energy management to distribute the power to both storages can be mathematically optimized applying Stochastic Dynamic Programming (SDP), considering stochastic influences of the driving process. To handle different conditions and driving cycles, we propose self-optimization control strategies involving multi-objective optimization. These strategies are able to autonomously adapt their behavior and relevance of objectives, offering an optimal and secure operation in different situations.","PeriodicalId":199452,"journal":{"name":"2013 International Electric Machines & Drives Conference","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114538562","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}

In order to deliver the concepts successfully hardware based learning tools are frequently used in undergraduate and graduate level courses. But most of these tools fall below expectations due to their complexity, lack of functionality or cost. This paper presents a learning tool on motor drives which addresses most of these issues. This proposed learning tool has the capability to deliver effective learning experiences on different types of motors discussed in advanced driving courses. The learning tool comes with user software which provides additional functionalities, such as the ability to manipulate closed loop variables, monitor real time speed variation, control firing patterns, log data and program the motor speed variation. The proposed learning tool is ideal to be incorporated in lab sessions to deliver important concepts in motor drives effectively and efficiently.","PeriodicalId":199452,"journal":{"name":"2013 International Electric Machines & Drives Conference","volume":"25 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116699755","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}

Usually, IPMSMs efficiency is increased by minimizing the controllable loss such as copper or/and iron loss. However, the parameters of an IPMSM vary with operation conditions due to magnetic saturation, and the iron loss is highly non-linear, both of which increase the difficulties of searching the true minimum loss solution. A method of generating optimal currents look-up tables for IPMSM loss minimization with due account of the voltage drop on the stator windings resistor is proposed. The parameter variations due to saturation effects and a high fidelity iron loss model are employed to generate the look-up tables via an optimisation process. The utility of the loss minimisation algorithm is illustrated through simulation studies.","PeriodicalId":199452,"journal":{"name":"2013 International Electric Machines & Drives Conference","volume":"68 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132038416","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 considered marine propulsion application, the reduction of the ripple torques is of critical importance which explains the choice of a five-phase winding. From a multi-machine modelling of the five-phase machine, a reference back-emf spectrum is determined as design objective. To fulfill this requirement, it is decided to adapt the magnet shape. To perform this task, an analytical air gap field computation is developed and validated by using a finite element analysis software (FEMM). A particular trapezoid magnet shape is then determined for the case study. In comparison with the initial rotor made with fully pole-pitch magnets, the new magnet shape almost eliminates the pulsating torque. Furthermore, the average torque to magnet volume is improved which can be considered as a better use of the magnet material.","PeriodicalId":199452,"journal":{"name":"2013 International Electric Machines & Drives Conference","volume":"109 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134582345","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}
