The impact of this approach on the mechanical and the electromagnetic design of the rotor active part is presented. In the end, the approach leads to a reduced cogging torque with simultaneously decreased leakage flux. Using conventional manufacturing technologies, e.g. punching or laser cutting, skewing the laminated soft-magnetic rotor active part and maintaining the magnet pockets axial straight would lead to a variety of lamination cross sections. The presented approach can hence be realized usefully by means of Additive Manufacturing (AM) technologies.Therefore, a short review of metal-additive manufacturing in the field of electric machines and the common practice of skewing in PMSMs is given in a first step. After this, a PMSM with barshaped buried magnets was chosen to serve as reference. 3D electromagnetic finite element analyses (FEA) of the non-skewed reference machine, of a conventionally step-skewed rotor and of the new continuously skewed rotor concept are performed. Continuously twisting the rotor active part around the magnet pockets leads to the need of adjusting the stray paths flanking the magnet pockets. The trade-off between minimizing leakage flux and maximizing mechanical strength is pointed out and the outcome additional mechanical stress FEA is shown. The impact of the stray paths and the skewing angle on the rotor air-gap flux density distribution is investigated in detail which leads to the evaluation of the resulting cogging torque of the different rotor concepts. Finally, guidelines for designing continuously skewed PM rotors using the possibilities of AM technologies can be derived.","PeriodicalId":207935,"journal":{"name":"2020 International Symposium on Power Electronics, Electrical Drives, Automation and Motion (SPEEDAM)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125357606","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 paper presents the results of a feasibility study that has been developed in order to sizing both power electronics and energy storage system that could be arranged in the railways AC/DC substations for recovering the train braking energy in 3 kV DC railway systems. Based on the evaluation of the recoverable energy during one day of operation in a given railway station, the paper discusses a suitable configuration for a braking energy recovery system that could be used to feed two associated electrical utilities, such as an electric vehicles charging station and the electrical distribution circuits of the railway station. According to available experimental data concerning the braking transient of a number of train arrangements, a suitable mathematical model in Matlab has been developed by taking into account the overall train traffic in a given mid-size railway station, so as to estimate the recoverable energy during 24 hours traffic operation. Then, the results of this study have been considered as input for developing the technical specification of both the power electronic converter and the battery energy storage that would be used to arrange the envisaged system for recovering energy from train braking transients.","PeriodicalId":207935,"journal":{"name":"2020 International Symposium on Power Electronics, Electrical Drives, Automation and Motion (SPEEDAM)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127627262","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 model validation, the complex model impedance is compared to the measured impedance of eleven electrical machines of the same type. Furthermore, the lumped equivalent circuit parameters are individually identified for every single electrical machine and the resulting data is statistically interpreted.

The article describes a two blades Magnus wind turbine whose cylinders rotate by means of embedded motors. To avoid a von Karman vortex street effect that occur when the cylinders rotate in the air flow, as well as to ensure maximum power, the optimal ratio between the wind speed and the cylinder rotation speed is determined using finite element analysis.
