SYSTEM AND MANUFACTURING METHOD FOR ASSEMBLING A LAMINATION STACK WITH A TWO-COMPONENT ADHESIVE AT LOWER TEMPERATURES

Abstract: methods and systems are disclosed for increasing rotor rigidity without compromising magnetic parameters of a plurality of permanent magnets by manufacturing a lamination stack using a two-component adhesive. in one example, a method includes for each lamination of a plurality of laminations, applying a first component of a two-component adhesive to one side of a lamination of a rotor and a second component to an opposite side of the lamination, stacking the plurality of laminations such that keyways and cavities of each of the plurality of laminations are aligned to assemble the lamination stack, inserting and positioning magnets in slots of the lamination stack and binding the magnets in their respective slots with glue, and applying pressure and temperature below demagnetization temperature of the magnets to bind the plurality of laminations together.
