Rotating Electrical Machines: We Know that electromechanical energy conversion takes place whenever a change in flux is associated with mechanical motion. Speed voltage is generated in a coil when there…
Energy in Magnetic System: Energy in Magnetic System - The chief advantage of electric energy over other forms of energy is the relative ease and high efficiency with which it…
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…
Transformer Cooling System: Transformer Cooling System (Large Units) - Basically, there are two seats of losses in a transformer namely: Core, where eddy current and hysteresis losses occur (caused by…
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…
