Principle of Operation of Induction Motor: The Principle of Operation of Induction Motor in Figure 9.4 shows the cross-sectional view of an induction motor. The stator is fed from a 3-phase supply of voltage V/phase…
Construction of Induction Motor and Types of Rotor in Induction Motor: The stator of an Construction of Induction Motor is similar to that of a synchronous machine and is wound for three phases, modem practice…
Introduction to Induction Machine | Use of Induction Motor: The Introduction to Induction Machine is an important class of electric machines which finds wide applicability as a motor in industry and in its single-phase form…
Brushless DC Motor: The term Brushless DC Motor is applied to many configurations of ac synchronous motors in which semiconductor control is used to control stator currents such that maximum torque is obtained at a…
Single Phase Synchronous Generator: Certain applications, usually restricted to less than 10 kVA are better served by a Single Phase Synchronous Generator. Examples are emergency, domestic/office supply, portable power for construction tools etc. Because of…
Short Circuit Current in Synchronous Generator: The Short Circuit Current in Synchronous Generator being electrical in nature is much faster than the electromechanical dynamics discussed already. It will, therefore, be assumed that by the time…
Hunting in Synchronous Machine: So far the operation of the synchronous machine under steady-state conditions at constant (synchronous) speed has been considered. Under these conditions of Hunting in Synchronous Machine where Pe= electrical power output…
Parallel Operation of Synchronous Generator: We already know that synchronous machine connected to infinite bus-bars. Parallel Operation of Synchronous Generator of two finite size will be considered, which is the way large practical size generators…
Slip Test on Synchronous Machine: Direct and quadrature axis reactances of a salient-pole synchronous machine can be estimated by means of a test known as the Slip Test on Synchronous Machine. The machine armature is…
Two Reaction Model of Salient Pole Synchronous Machine: In a Two Reaction Model of Salient Pole Synchronous Machine, the flux established by a mmf wave is independent of the spatial position of the wave axis…
