Calculation Of Non-Stationary Magnetic Field Of The Polarized Electromagnet With The External Attracted Anchor

Approach to modeling of transition process of the polarized electromagnet of a direct current at a fixed value of a working gap through the solution of a problem of non-stationary magnetic field with the attached electric chain in a complex of the ELCUT 6.0 programs (the professional version) is considered. In the studied design of the polarized electromagnet with the external attracted anchor there are two independent magnetic fluxes. The working magnetic flux arises under the influence of the winding magnetizing forces of the managing director. The polarizing magnetic flux is created by two permanent magnets from magnetic NdFeB alloy (neodymium - an iron - pine forest). In the absence of current in a winding the anchor is affected by the attraction force created by the polarizing magnetic flux. Action of the polarized electromagnet depends on size and the direction of the working magnetic flux created by the magnetizing winding force. Considering wide circulation of electromagnets in various areas of the equipment, including the polarized electromagnets, expansion of opportunities of methods of their research in the established and transition processes represents a relevant task. On the basis of the solution of a problem of non-stationary magnetic field of the polarized electromagnet in a complex of programs ELCUT pictures of magnetic field are calculated and his temporary dependences at connection of a winding of management to a source of constant tension are received.
