They can carry significantly higher current densities compared to traditional copper conductors. Consequently, much higher air-gap magnetic flux densities and current loads can potentially be created, but at the expense of a more complex cryogenic cooling system. This paper presents a study of the possibility of creating a 1 MW electric motor using superconductors for the stator winding. Designs with radial flux and axial flux has been considered. For the design with radial flux, an external rotor motor has been chosen as having the potential to achieve higher power densities. Further optimization of electric motors with an external rotor concerned changes with the geometry of the stator tooth zone and the use of other magnetic rotor systems. During optimization, a reduction in the mass of active materials and a reduction in torque ripple has been obtained in comparison with a standard design of an electric motor with radial magnetic flux. Calculations were also carried out using a copper winding in cryogen, which showed comparable results with the design of an electric motor with high-temperature superconductors.","PeriodicalId":363631,"journal":{"name":"2020 International Conference on Electrotechnical Complexes and Systems (ICOECS)","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122727676","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 allows to obtain high quality indicators, such as the ability to measure variable and constant currents: error ± 0.1%; repeatability of characteristics from sample to sample ± 0.02%; linearity ± 0.1%; dynamic range > 4 kHz, temperature sensitivity <± 0,002%/°С; the mass of the sensitive element does not exceed 15 kg (for comparison, the mass of magnetic current transformers of similar measurement ranges is an order of magnitude more).Based on the foregoing, it was decided to develop a measuring system based on the Faraday magneto-optical effect in optical fiber and use digital fiber-optic and electronic components to process the output signal of the measuring system.","PeriodicalId":363631,"journal":{"name":"2020 International Conference on Electrotechnical Complexes and Systems (ICOECS)","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122897353","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}

To such means of electroheating includes low-temperature induction heating, which provides a guaranteed increase in quantitative and qualitative production indicators, which can significantly reduce the cost of production, which is important to save energy resources especially with increased tariffs. Various aspects of the development of such induction heating systems are discussed, with a particular focus on ensuring the safety and automation of installations used in the oil and gas industry. The issues of using distributed induction heating in the oil industry are considered using the example of the induction method for oil and gas producing wells with the aim of facilitating the production of highly viscous oil, eliminating tar-tar deposits and preventing the formation of hydrate-paraffin plugs. The results of modelling the heating of the inductor - tubing system at various positions of the load-bearing and non-load-carrying cable-inductor are presented. During the simulation, data were obtained on the temperature of the oil product were obtained under various oil production conditions.","PeriodicalId":363631,"journal":{"name":"2020 International Conference on Electrotechnical Complexes and Systems (ICOECS)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126424828","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}
