Transformer Wire Length Calculator

NewFree

Calculate required wire length, number of layers for transformer design

Wire Length Calculation Formulas

Formula: Turns per Layer = H / (d + spacing)

Formula: Number of Layers = ceil(N / Turns per Layer)

Formula: Winding Thickness = Layers × (d + t)

Formula: Mean Turn Length = π × (D + Thickness)

Formula: Wire Length = N × Mean Turn Length

Where:

  • H = Core height
  • d = Wire diameter
  • N = Number of turns
  • t = Layer insulation thickness
  • D = Core diameter
