Abstract: In the condition of certain electromagnetic levitation coil and
spherical sample, according to the expressions of levitation force and absorbed
power in magnetic field, the relationship between levitation force, absorbed
power and high frequency power supply frequency is established in this paper.
In addition, the effect of the power supply frequency on the levitation force
of the coil and the absorbed power of the sample is analyzed, and the general
rules of frequency parameter selection are confirmed. Finally, a guiding role
in the frequency selection of high frequency power supply in electromagnetic
levitation melting is played.
Keywords: Electromagnetic levitation melting, frequency, levitation force, absorbed power
