How do you make induction heating coils?
5 basic tips for designing your induction heating coil
- Higher flux density near the heating area means a higher current is generated in the part.
- The greatest number of flux lines in a solenoid coil are toward the center of the coil.
- The geometric center of the coil is a weak flux path.
How does the induction heater work?
An induction heater consists of an electromagnet and an electronic oscillator that passes a high-frequency alternating current (AC) through the electromagnet. The rapidly alternating magnetic field penetrates the object, generating electric currents inside the conductor, called eddy currents.
How can I increase my induction heater power?
The induction coil efficiency upon heating of a steel wire can be increased by increasing its magnetic permeability. This can be achieved by increasing the current frequency and decreasing the magnetic field, which leads to an increase in the induction coil length at a constant power.
What materials can be induction heated?
Induction heating is a fast, efficient, precise and repeatable non-contact method for heating electrically-conductive materials such as brass, aluminum, copper or steel or semiconducting materials such as silicon carbide, carbon or graphite.
Will an induction heater heat aluminum?
Induction heating is most useful on ferrous metals because of its magnetic properties. However, induction heating can also heat up aluminum somewhat, which is often enough to remove decals, vinyl and bonded trim.
Are induction heaters efficient?
Induction heating proves to be a highly efficient method for industrial heating applications. A 1998 study conducted by Lawrence Berkeley National Laboratory for the Department or Energy, found induction cooktops to transfer 84% of the power to the load vs. only 71% for electric coils and 40% for gas.
What are induction coils used for?
Induction coils were used to provide the high voltage for electrical discharges in gases at low pressure and as such were instrumental in the discovery of cathode rays and X-rays in the early 20th century. Another form of induction coil is the Tesla coil, which generates high voltages at high frequencies.
Will an induction heater work on stainless steel?
Induction cooking surfaces work well with any pans with a high ferrous metal content at the base. Cast iron pans and any black metal or iron pans will work on an induction cooking surface. Stainless steel pans will work on an induction cooking surface if the base of the pan is a magnetic grade of stainless steel.
How fast is induction heating?
Induction heating finds applications in processes where temperatures are as low as 100ºC (212°F) and as high as 3000°C (5432°F). It is also used in short heating processes lasting for less than half a second and in heating processes that extend over several months.
How hot can induction heating get?
Induction heating is used in processes where temperatures are as low as 100 ºC (212 °F) and as high as 3000 °C (5432 °F). It can be used in brief heating processes that are on for less than half a second and in heating processes that are on for months.
