ABSTRACT
Any magnetic field (Hi, Bi) zone within the IM is characterized by its stored magnetic energy (or coenergy) Wm.
ILdVHB 2 1W
mi =⋅= ∫∫∫ (6.1) Equation (6.1) is valid as it is when, in that region, the magnetic field is produced by a single current source, so the inductance “translates” the field effects into circuit elements. Besides the magnetic energy related to the magnetization field (investigated in Chapter 5), there are flux lines that encircle only the stator or only the rotor coils (Figure 6.1). They are characterized by some equivalent inductances called leakage inductances Lsl, Lrl.
