  • Method of reclaiming electric motor laminations
    Patent number: 4508583
    Abstract: A method of reclaiming laminations from electric motors enables reclamation with epoxy filled stators. The stator is removed from the housing and placed on a support in clamps. One clamp is moved with respect to the other to separate a section of the stator from the remaining portions of the stator. This also pulls windings from the separated section. The stator is then reclamped and another section is pulled from the stator. When broken into individual sections free of windings, the epoxy filler can be loosened either chemically, or by heat, or by heat and quenching.
