1. An analysis on electric and magnetic behaviour on an induction planar actuator
The induction planar actuator, i.e. IPA, proposed in this study presents an electromagnetic structure formed by a static ferromagnetic core with an aluminium plate that corresponds to the secondary, and a mover, also called primary. The latter comprehends two three-phase windings, mounted in an armature core, which are orthogonal to each other. When they are

2. An estimate of the magnetic lossesin reactors with natural saturation / Uma estimativa das perdas magnÃticas em reatores com saturaÃÃo natural
This work has the purpose of showing an estimate of the modeling of power dissipated in ferromagnetic structures with profoundly saturated parts, through the behavior of the magnetic induction wave form experimented in many parts of the structure when used in saturated reactors. For each one of the analyzed prototypes, the bonding forms of the primary windin

3. A new current transformer model
This paper presents a current transformer model that is useful on low frequency applications. To describe the iron core magnetic behaviour of the iron core, a hysteresis model is proposed, which is able to generate minor asymmetric loops and remanent flux. The effects of classic eddy current losses and anomalous losses are represented by linear and nonlinear
