Machine Questions. of coreless induction furnace (D) high frequency eddy current =conductor current Total force, where z=total number of conductors (2) This force (and therefore torque) is constant because both the flux density wave and current distribution are fixed in space at all times.
Now the torque developed is (3) where. Mathematical modelling of frequency and force impacts on averaged metal flows in alternating magnetic field. distributions of the axial velocity at crucible axis and at the level of upper vortex.
Coreless induction furnace and method of melting and stirring metals in this Current, patent USCited by: 3. New measurement techniques for local velocity, magnetic field, and current density have been applied to the study of electromagnetic and hydrodynamic phenomena in a coreless induction furnace.
The process of the motion of solid particles in the metal melt is simulated in the present paper. The model consists of the flow and the particles movement calculation at each time step.
The main task of the present work is to design and construct a coreless induction furnace. Many analytical methods could be applied to induction heating and melting problems. The most suitable method for the present work is equivalent circuit method, a second approach is the superposition method, to check the results of the first method in one step of the to the use of these two.

As the special characteristics of MW heating, three different heating aspects have been pointed out, namely they are the internal heating, the rapid heating and the selective heating (Bykov, et al., ).File Size: 42MB.

Since the no-load current is a very small percentage of the full load current, which can be in the range of to 2% (for large power transformers, e.g., above MVA, no-load current can be as small as about %), the voltage drop in LV resistance and leakage reactance is negligible as compared to the rated voltage (in figure ).
