Classification and research of electro-technical devices with unclosed magnetic core

The article is describes the classification and study of the magnetic field and its power parameters for unclosed magnetic core electrotechnical devices. The ANSYS simulation software has been used. The features of structures based on an open-loop magnetic system (iron separators), an open magnetic system (concentrators), and a hybrid magnetic system are shown.The magnetic field patterns and force characteristics are obtained as a result of numerical calculations created on the finite element method (FEM) in the ANSOFT software. Results of experiment: the electrotechnical device with unclosed magnetic core allows due to its design and configuration, of the magnetic field, the use of concentrators with different attachments to improve the power parameters of the magnetic field, ponderomotive force and operational properties of these devices.
