ブレーキなどの電磁連結装置が知られている。In general, when an electromagnetic coil is applied, an armature attached to an input rotating member is magnetically attracted to an output rotating member, and an electromagnetic clutch, which is a mechanism that transmits the rotational force of the input rotating member to the output rotating member, or a similar rotating An electromagnetic coupling device is known, such as an electromagnetic brake, which is a mechanism for braking the rotation of a rotating member by being magnetically attracted to a fixed member when an armature attached to a shaft is applied to an electromagnetic coil.

ている。Therefore, the armatures in these electromagnetic coupling devices are required to have high magnetic permeability to enable rapid magnetic attraction, and are also required to have low coercive force to quickly separate when the magnetism is interrupted. Therefore, for example, pure iron and low carbon steel are used in their manufacture.

置自体を使用寿命に至らしめるものであった。However, although pure iron and low carbon steel have high magnetic permeability and low coercive force, they have poor wear resistance and lubricity, so the above armature is relatively short. The amount of wear exceeded the allowable amount of wear over time, and the electromagnetic coupling device itself reached the end of its service life.
