Abstract

Abstract: The non-contact torque transmission mechanism and the advantages of the longitudinal coupled permanent magnet coupler with adjustable speed system was introduced.Based on the 3D moving eddy current field,the complete finite element model of the single cylindrical copper sleeve permanent magnet coupler was established,then the magnetic field and eddy current field were analyzed.The distribution of magnetic field and eddy current field were acquired,and the key parameters were analyzed by Ansoft Maxwell software,such as the number of magnetic poles,the thickness of the permanent magnet,the thickness of cylindrical copper sleeve and the air-gap,which affect eddy current density.Based on this,the distribution of the coupling force between the permanent magnetic field and eddy current field was analyzed,the problem of radial force imbalance was solved.The prototype trial-production of the permanent magnet coupler with double copper sleeves were presented by choosing four sets of different structural parameters,and the experiments were carried out,the results of the simulation and the experimental value were compared to verify the correctness of the finite element analysis and transmission characteristics research method.

Key words: permanent magnet coupler with double copper sleeves, finite-element, eddy current, coupling force, experimental research
