Abstract
The technique for parameters determination of magnetic skin effect on ferromagnetic plate at a specified pulse of magnetic field intensity on the plate surface is proposed. It is based on a frequency-domain method and could be applied for a pulsing transformer, a dynamoelectric pulse generator and a commutating inductor that contains an imbricated core. Due to this technique, such plate parameters as specific heat loss energy, the average power of this energy and the plate temperature raise, the magnetic flux attenuation factor and the plate q-factor could be calculated. These parameters depend on the steel type, the amplitude, the rms value, the duration and the form of the magnetic field intensity impulse on the plate surface. The plate thickness is defined by the value of the flux attenuation factor and the plate q-factor that should be maximal. The reliability of the proposed technique is built on a common frequency-domain usage applicable for pulse transient study under zero boundary conditions of the electric circuit and the conformity of obtained results with the sinusoidal steady-state mode.
Highlights
Many of today’s electrophysical devices contain an imbricated core run under the pulsed electromagnetic field (EMF)
It is possible to solve EMF equations by a numerical technique. This technique is quite cumbersome so it makes determination of the pulsed EMF influence on imbricated cores too complicated [6-8]
The EMF pulse is prescribed as an identical magnetic field intensity on plates lateral surfaces HS (t ) – i.e. pulse time function t with duration τ and directed along the Z axe (Figure 1)
Summary
Many of today’s electrophysical devices contain an imbricated core run under the pulsed electromagnetic field (EMF). The using of the frequency-domain method simplify computations and allows us to consider the shape, amplitude and duration of pulsed EMF at its diffusion in the ferromagnetic plate [9]. Such task as calculation of the magnetic skin effect in the ferromagnetic plate due to the frequency-domain method and choosing the plate thickness with respect to the pulsed EMF shape, duration and amplitude seems to be a vital one and reflects the purpose of the paper.
