An armature is provided on the yoke body. The yoke body is axially retracted at the corresponding armature. The indentation distance is the axial width of the armature. The armature is welded to the yoke body . There is a permanent magnet coil in the pass body.The permanent magnet coil is connected to the yoke body through a coupling.The permanent magnet coil has a bending section. The bending section has the same curvature as the edge of the coupling in the radial section . Both ends extend to the inner side of the center of the permanent magnet coil, and the bent portion faces the center end surface of the permanent magnet coil and opposes the end surface of the yoke body. The inner coil of the permanent magnet coil is provided with a plurality of through grooves on the inner wall of the inner coil. The through slot width is one to two millimeters. The electromagnetic clutch shortens the axial width of the entire yoke body, saves raw materials, effectively ensures the stability of installation, can extend the service life of the electromagnetic clutch to a certain extent, and has good safety performance and flexible installation methods.
Although the above solution has the above-mentioned advantages, it still has the following technical problems: it still fails to improve the above technical problems and has poor practicability.
