Specify your equipment
Buyer drawings, overall and interface dimensions, specified materials, insulation requirements, lead arrangement, assembly requirements and quantities.
Discuss your projectSelection questions
What must a winding drawing specify?
Specify conductor material and section, turns, winding arrangement, insulation, cooling ducts, lead positions and dimensional tolerances using the buyer’s approved design.
Which interfaces govern coil assembly?
Check core-window fit, axial and radial dimensions, clamping, leads and insulation interfaces. Agree inspection points and protective packing before production.
