Coil electrical parameters – coil inductance, resistance, and number of turns all play a very important role for the optimal performance of the coil. The coil must be designed so these parameters match well with the output parameters of the induction power supply. This way the energy can be efficiently transferred from the power source into the heated work piece.
Cooling requirements – The coil is usually made from a copper tube, but can be also made from any conductive material or dry cable. Usually water cooling is required to dissipate the energy lost in the coil. For this reason, the water cooling requirements need to be carefully calculated – water flow, water pressure, cooling liquid type, etc.
