Stator core iron loss was reduced by 60% by optimizing the thickness and microstructure of iron-cobalt alloy, which shows a high induction, and by developing a new adhesive and surface treatment technology. A manufacturing process was developed that satisfies the required magnetic characteristics and dimensional accuracy, and a new production system was constructed for laminated parts. The newly developed stator enabled a 20% reduction in the motor size.
