induction Wire Heating Coil

Induction coil (inductor) is very impotant for the induction heating system, it can influence the output frequency and ouput current (power) of induction heater. When the length of induction coil is too long or too short, induction heat can't work or the machine can't output a best power.

However, there is no formula for you to design an inductoin coil for each application, it's often depend on experience, and this is the biggest disadvantage of induction heating.

The key point of how to design a best shape of induction coil is to test the output frequency of induction coil, if the output frequency can mathch the machine's best frequency, it will often bring a best and stable output power.
