AV-formulation (Electrical Machine)

By

Using Ampere’s law and the magnetic vector potential and applying the appropriate material equation yields:

This equation is called the AV-formulation of the magnetic field. The presence of the derivative in time indicates the magneto-dynamic field problem. By substitutingtmp10274_thumbthis formulation is transferred from the time domain into the frequency domain:
