Laminations reduce eddy current losses by breaking up conductive paths. Thin insulated steel sheets minimize circulating currents induced by changing magnetic fields, improving efficiency.
Electrical steel (silicon steel) with 2-3.5% silicon content is standard. Grades like M19, M36, or M43 offer specific magnetic properties. Insulation coatings (C-4, C-5) prevent interlamination shorts.
Core geometry, slot design, and material quality directly impact efficiency, torque characteristics, cooling, and noise levels. Proper design minimizes magnetic saturation and losses.
