There is a certain shafting deviation during the installation of magnetic clutch (MC). In view of the angular and radial deviation between the two rotors, the magnetic field distribution, eddy current distribution, axial magnetic pull, torque and other basic electromagnetic characteristics of the MC are analyzed and studied by deviation model and three-dimensional finite element method. With the increase of the radial deviation distance, the air gap magnetic field and eddy current distribution of conductor disk are shifted along the radial direction, and the torque of MC decreases gradually. With the increase of the angular deviation, the air gap magnetic field and eddy current density are asymmetrically distributed, and it shows obvious unbalanced axial magnetic pull, but the output torque drops first and then rises steadily.
