To calculate the length of wire to make a compression spring, multiply the length of wire per coil by the total number of coils. The linear resistance of a length of tape or wire may be calculated from its electrical resistivity. Usually, helical coils employed to heat round workpieces have the highest values of coil efficiency and internal coils have the lowest. In the majority of instances, the distance increases corresponding with the diameter of the part, normal values being 0.75, 1.25, and 1.75 inches (19, 32 and 44 mm) or billet-stock diameters of approximately 1.5, 4 and 6 inches (38, 102, and 152 mm), respectively. The size of a coil is often determined by the time required to raise the solution to operating temperature. The equation for calculating the total heat added to or taken from a fluid flow is: Q = M * Delta H. Where: Q= The amount of heat transferred to or from the fluid (BTU/hr) M= Mass flow rate of the fluid (lb/hr) Delta H= The change in enthalpy of the fluid (BTU/lb) There are three main factors that impact an induction coil’s optimal coupling distance: It is vital to remember that handling and process conditions dictate coupling. Tank agitation - Agitating the solution in your tank improves heat transfer properties and might lead to smaller coils. The XY Aligner provides basic XY manipulation for low duty-cycle applications where high precision is not required.

For static surface heating, where the part can be rotated but is not moved through the coil, it is recommended to use a coupling distance of 0.060 inches (0.15 cm) from part to coil. If the length of the coil is over eight times its diameter, uniform heating at high power densities can be challenging. Short heat-up times require large coils. Thus, the corresponding engineering calculations must be made to determine sufficient heating surface area, diameter and length for the pipes. The efficiency of coupling between the windings is inversely proportional to the square of distance between them. Similar uniformity can be attained by opening up the coupling between the coil and the part so that the magnetic flux pattern intersecting the heated area is more uniform, yet, this also decreases energy transfer.
