Calculation method
Calculation method
Wire length per usable ring (mm)
math.pi*(a+b)+d
Complete rings
math.floor(c/(math.pi*(a+b)+d))
Unused wire (mm)
c-math.floor(c/(math.pi*(a+b)+d))*(math.pi*(a+b)+d)
Symbols and units

Assumptions & limits
Assumptions & limits
- Ideal no-pitch circular coil model with supplied per-ring loss added to circumference budget. Does not model helical pitch, springback or saw geometry. Supported limits: All numeric inputs must be finite. Only the explicitly described mathematical scenario is supported.
