Magnetic coupling for contactless torque transmission along a rotation axis and method for producing a magnetic coupling

摘要

The invention relates to a magnetic coupling 100 for contactless torque transmission along an axis of rotation 105, wherein the magnetic coupling 100 has at least one outer rotor 110 having on an inner side permanent magnet 115 with sections of different polarity, the magnetic coupling 100 further comprises an inner rotor 120 which within the outer rotor 110 is disposed and on one outer side permanent magnet 125 having portions of different polarity and the magnetic coupling 100 finally has a demagnetization protective layer 305 to reduce demagnetization of the magnetic coupling 100, the demagnetization protective layer 305 is disposed between the inner 120 and the outer 110 rotor.
