Torque Equation of Synchronous Motor: Figure 5.36 shows a Torque Equation of Synchronous Motor with a round rotor. The rotor is initially stationary with fixed north-south poles created by dc…
MMF of AC Distributed Winding: It has been seen earlier that the armature what-when-how.comof a practical machine has distributed winding wound for the same number of poles as the field…
Three Phase Synchronous Generator: Practical synchronous generators are always of the 3-phase kind because of the well-known advantages of a 3-phase system. If two coils were located at two different…
Synchronous Machine Working Principle: Figure 5.2 shows the simplified version of an ac Synchronous Machine Working Principle with a 2-pole field winding on the rotor and a single coil aa'…
Dynamical Equations of Electromechanical Systems: Dynamical Equations of Electromechanical Systems - Figure 4.19 shows an electromagnetic relay whose armature is loaded with spring K, damper B, mass M and a…
Electromechanical Energy Conversion via Electric Field Energy: Electromechanical energy conversion via the electric field is analogous to the magnetic field case studied earlier. Charge in the Electric Field Energy is…
Multiply Excited Magnetic Field System: Multiply Excited Magnetic Field System - Singly-excited devices discussed earlier, are generally employed for motion through a limited distance or rotation through a prescribed angle.…
Principle of Electromechanical Energy Conversion: Principle of Electromechanical Energy Conversion is a reversible process and Eqs (4.26) to (4.29) govern the production of mechanical force. In Fig. 4.4 if the…
