What is the recommended core structure design?

A good core must have step-lap joints (5, 7, or 9 steps) rather than butt joints to reduce loss, noise, and magnetizing current.

What manufacturing quality factors should be checked?

Check cutting methods (laser/shear), stress control, annealing processes, lamination insulation, and stacking factor to avoid increased core loss.

What standards and tests are required for core evaluation?

Always require test data for no-load loss, excitation current, and sound level, complying with IEC 60076, IEEE C57, and GB/JIS/EN standards.
