The constant need of electrical drive trains and therefore electrical machines requires the selection of the right electrical machine regarding the application requirements. Within this work, the different machine types are briefly opposed to each other regarding their disadvantages and advantages. Then, existent machines of those types are compared based on power density (volume, weight) and efficiency. Finally, reliability is an important factor for the selection procedure, thus it will be explained how reliability estimation can be used for multi-phases permanent magnet synchronous machines, even though there are not enough data available.","PeriodicalId":287492,"journal":{"name":"2015 International Conference on Electrical Systems for Aircraft, Railway, Ship Propulsion and Road Vehicles (ESARS)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131015457","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}

Its reliability determines the power traction system security, and its thermal safety issue is one of the key researches, especially the working temperature rise of the stator windings and slot insulation. Based on the forced air cooling system and the multiple operating states, the fluid flowing states and heat transfer in traction motor is investigated. A 2D temperature analysis method is proposed, in which the highest temperature of insulation section determine based on the 3D fluid calculation is taken as the analysis model. This could ensure the accuracy of the insulated thermal safety assessment, and save a lot of computing time.

These impacts and their reduction need several investigations.

Some of common features are improving the quality of the power supply of particularly sensitive loads to network disturbances, such voltage sag compensation or short interruptions, peak shaving, active power factor correction. Such type of devices, especially with the primary function of peak-shaving, are very suitable coupled with Electric Vehicle Quick Charging Stations (EVQCS) due the considerable power absorbed by them from the three-phase network (in our case 400 V-50 Hz) especially at the beginning of the charging (several kW for some minutes). In this way, the network will be relieved of high power peaks need that would cause an impact on utilities and necessary investments by the distributor. This paper describes an innovative power conditioning system with energetic storage based on Lithium-Ion Ultracapacitors which have high performance in terms of specific energy and long service life. The device is designed and built to be a support for an EVQCS. The prototype is actually installed in the experimental area of Enel Ingegneria e Ricerca, located in Livorno, where a series of tests has proven its functionality and benifts for the grid. Future tests will be dedicated on interaction with a Li-ion storage system to improve energy services.","PeriodicalId":287492,"journal":{"name":"2015 International Conference on Electrical Systems for Aircraft, Railway, Ship Propulsion and Road Vehicles (ESARS)","volume":"84 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130970783","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}

Nonlinear flux observer and torque-current maximization criterion take into consideration the effect of magnetic saturation hence improving the torque-flux tracking accuracy. The main advantage of the proposed controller is it's physics-based cascaded structure and simplicity of practical implementation.
