Method of forming a coupling disc for an electromagnetic coupling

摘要: A method of forming non-magnetic barriers in the coupling disc (e.g., armature or rotor) an electromagnetic such as a clutch brake. The is carried out by moving relative to laser beam which cuts slot through disc. In one embodiment, filled throughout its entire length material, filling being effected continuously advancing wire toward cause be melted and flow into newly formed slot. another advanced intermittently form short bridges beween relatively long slots.
