Firstly, uniaxial tensile tests were conducted on the specimens at different temperatures to obtain the mechanical parameters of the silicon steel material at the corresponding temperature; secondly, the damage parameters at the corresponding temperature were fitted by the finite element inverse calibration method, and the temperature distribution law of the motor rotor was obtained by CFD calculation; then, based on the material parameters and temperature data, the damage condition and fatigue life of the rotor under four different cyclic operating conditions were studied by the finite element method. The results show that under the rated cycle condition, the stress does not reach the yield limit of the silicon steel material, and the volume fraction of holes inside the rotor material is still the initial hole volume fraction; under the peak cycle condition and rated-peak cycle condition, although the magnitude of the stress and stress distribution of the rotor are almost the same, the equivalent plastic strain of the latter is larger than that of the former, and the corresponding hole volume fraction is also larger; under the limit cycle condition In the ultimate cycling condition, the stress, equivalent plastic strain and pore volume fraction of the rotor have increased more obviously than the first three; and under the same cycling condition, the fatigue life of the rotor is smaller than that without considering the internal damage of the material.</p>","PeriodicalId":15577,"journal":{"name":"Journal of Electrical Engineering & Technology","volume":"13 1","pages":""},"PeriodicalIF":1.9,"publicationDate":"2024-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141584935","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One power frequency cycle after fault is divided into 12 time periods according to the valve state, then the 12 time periods of high-voltage bridge faults are classified into 6 types based on the common characteristics, and the 12 time periods of low-voltage (LV) bridge faults are classified into 3 types. For each type of time period, the current flow path is analyzed, the corresponding circuit equation is written. By combining multiple time periods, the expressions of valve-side current and grid-side current are solved. On this basis, the differential current of converter transformer differential protection is derived and the performance of differential protection under valve-side winding single-phase grounding is studied. The research results show that when a single-phase grounding fault occurs in the valve-side winding of the LV bridge converter transformer, the second-harmonic ratio in the differential current is bigger than 15%, so the differential protection refuses to act due to mis-locking. In order to prevent differential protection from failing to act, an improved scheme of converter transformer differential protection is proposed. Through the logic coordination between the zero-sequence current unit and differential protection, the improved scheme can not only reflect various internal faults of converter transformer, but also ensure no action under the inrush current.

Furthermore, the efficiency of the converter can also be increased because each phase can achieve soft switching regardless of the number of phases. This paper provides a detailed analysis of the operating principle based on the duty of the main switch (<i>S</i><sub><i>m</i></sub>) and the design method for resonant parameters using the equivalent circuit of <i>S</i><sub><i>m</i></sub>. To verify the feasibility, a 3 kW prototype IBSC is designed and implemented.

So a compromise between radial force and torque is usually applied in a classical control scheme of the BSRM, resulting in under-utilization of its optimal performance of both levitation and motion. For a 12/8-pole BSRM, this paper implements a levitation control in the efficient excitation region to maximize the radial load capacity, performs a torque excitation from the unaligned position to the aligned position and adjusts in real time the instantaneous total torque so as to improve its torque output. In a 12/8-pole BSRM, the efficient levitation excitation region of each phase consists of two equal-width sectors, and a rotor angular position cycle is formed with the six equal-width sectors. Based on the optimal objective within each sector and combined with the derived mathematical models of the radial force and torque, the corresponding current constraint is designed to calculate the five currents in the two-excited phases. Further, the control scheme for a 12/8-pole BSRM under efficient levitation excitation is developed to simultaneously regulate four instantaneous values of two radial forces and two phase torques.
