Lamination reduces eddy current losses by breaking up conductive paths. Solid cores would generate significant heat from circulating currents in changing magnetic fields, reducing efficiency by 15-25%.
Non-oriented electrical steel with silicon content (2-3.5%) is standard. Silicon increases electrical resistivity while maintaining magnetic permeability. Coatings provide interlamination insulation.
Manufacturing involves precision blanking/punching of electrical steel coils, deburring, insulation coating application, stacking with interlocking features or bonding, and heat treatment for stress relief.
