Unknown constants of this method are found using four known boundary conditions of the electromagnetic field on the common end surfaces of hollow cylinders: scalar magnetic potentials and three coordinate components of magnetic induction do not undergo a jump (discontinuity). If, for convenience of calculation, the magnetic sheets of the windings are located at these boundaries, the magnetic potentials on them will undergo a jump equal to the total current of the magnetic sheet. The distribution curves of magnetic inductions in the air gaps and the values of the electromagnetic torque of the motor are obtained, which are compared with the results of numerical calculation using the Ansys Maxwell program. The good agreement between the results obtained indicate the reliability of the proposed analytical model of a disk-type inverted motor.</p>","PeriodicalId":39312,"journal":{"name":"Russian Electrical Engineering","volume":"26 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140569363","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}

The use of a combined winding with a doubled number of parallel structures when connecting the star and triangle (D connection) windings in parallel in frequency-controlled asynchronous motors makes it possible to use thinner wires and to reduce additional losses and displacement of current by higher temporary harmonics of a current. Parameters of combined windings must be selected based on a refined analysis of electromagnetic processes due to the possibility of the occurrence of equalizing currents in the circuits between the phases of different windings. An algorithm for the interaction of coupled circuit electromechanical and field electromagnetic models is proposed, which allows for refined modeling of an operation of induction motors with combined windings from a frequency converter with pulse-width modulation of voltage.

Such converters are used in wind power plants, power transmission, and electric drives. The energy reserves in an MMC are distributed among many TCBs. The voltages and currents at the input and output of the MMC have small distortions, but control systems are complex, A decrease in the frequency of currents at the input or output of the MMC leads to an increase in voltage ripples of TCB capacitors. To limit pulsations, internal contour currents are introduced into the MMC, and zero sequence components are used in control devices.
