Abstract
Eddy current loss of stator core laminations in generators is a key factor affecting motor efficiency. This article systematically studies the formation mechanism and distribution characteristics of eddy current losses, with a focus on exploring the influence of laminated structure parameters, material properties, and insulation performance on losses. Through theoretical analysis combined with finite element simulation, the correlation mechanism between silicon steel sheet thickness, interlayer resistance, and eddy current loss was revealed. The research results indicate that optimizing the thickness of the laminate, improving the blocking ability of the insulation coating, and controlling the processing technology can effectively suppress eddy current losses.
Key words： Generator; Stator core; Stacking; Eddy current loss
