This article describes the methods of using composite magnetic soft materials in the railway transport and mechanical engineering. Soil state in two modifications of Fey and Fey are formed in the iron. Also in the text, the main temperature magnetic and non-magnetic properties of materials, and magnetic properties of materials at various different temperatures are highlighted. It has been noted that other material properties change at normal temperature also. In this regard, the study of new magnetic materials based on isolated iron particles is of interest to the theory of magnetism - the study of the mechanism of magnetic exchange through thin insulating layers with the formation of single-phase ferromagnetic ordering in a multiphase crystalline system.
The article describes the magnetic noise during the operation of a single-phase asynchronous motor due to the vibration of the stator package of the motor under the action of vibration-absorbing forces due to the interaction of harmonics of a magnetic field of various origins in the air gap of the machine. As a normalized parameter of vibration created by an electric machine, the effective value of the vibration velocity is adopted. Electric motors used in electric rolling stock operate in more difficult conditions in comparison with general industrial ones. In the electric rolling stock, various auxiliary electric machines are used. Despite the relatively low level of magnetic vibration of high frequency, due to its determining effect on the magnetic noise of single-phase motors, this component is of independent interest for research.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
