01 Jun Top Induction Cooktop “Hundred Core” Coil Disk
To able maximize the use to most top induction cooktop; it is important to know the difference of “hundred core” coil and the standard coil. This way, as a user of the cooktop you could correctly purchase what is apt for your needs.
What is “Hundred Core” Coil compared to regular Coil?
The so-called “hundred-core” coil reel is the multi-strand paint that winds the reel. The stranded wire is composed of more than one hundred mutually insulated enameled wires. During the winding process of each coil, the coils used are the slot-type reel skeleton, making the magnetic field distribution more uniform.
The structure of “Hundred Core” coil disk is not that different from an ordinary coil disk. To identify the difference between the “Hard Core” and regular coil disc, refer to the figure below.
The design of “hundred core” reel is mainly done to reduce the high frequency loss of the coil consumption, and improve the heating efficiency of the top induction cooktop.
When a conductor passes a high frequency current, the current density inside the conductor becomes different. In the same way, the current density at the surface of the large conductor, the current density inside the conductor is small, others have none. This is called High frequency current “skin effect”. The biggest trick of the skin effect is to increase the high frequency loss, so most high-frequency coils often used enameled wires insulated from each other and twisted into one.
After the main wire is coiled, the coil is coiled. Equally, the coil in the top induction cooktop also has a very surprising high frequency loss. In order to lower the coil in the induction cooker caused by high frequency loss, the coil of the induction cooker done by gluing multiple strands of enameled wire. Currently, the production technology and price is the reason why the grid that most induction cooker use mostly coiled by 18 to 38 enameled wires. Though, such coil loss is still large, so enterprises raise concern about energy saving that increased the number of sub-wires on the spool to make it less.
