Excitation Phenomenon in Transformer: It was stated already that the no-load current in a transformer is nonsinusoidal. The basic cause for this Excitation Phenomenon in Transformer, which lies in Transformer…
Real Transformer On Load Condition | Equivalent Circuit: Figure 3.11 shows a Real Transformer On Load Condition. Both the primary and secondary have finite resistances R1 and R2 which are…
Ideal Transformer on Load: In order to visualize the effect of flow of secondary current in a transformer, certain idealizing assumptions will be made which are close approximations for a…
Phasor Diagram of Transformer on No Load: Figure 3.5 shows the schematic diagram of a Phasor Diagram of Transformer on No Load with Two Winding, i.e. the secondary terminals are…
Application of Permanent Magnet Motor: Application of Permanent Magnet Motor are given in Table 2.1. These properties are: residual flux density Br, coercive magnetizing force Hc maximum energy stored (BH)max…
Define Permanent Magnet in Magnetic Circuits: Define of Permanent Magnet is an important excitation source (life long) commonly employed for imparting energy to magnetic circuits used in rotating machines and…
BH Curve Relationship (Magnetization Characteristic) for Ferromagnetic Material: In free space (also nonmagnetic materials), the permeability μ0 is constant so that BH Curve Relationship is linear. This, however, is not the…
