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…
Torque in Round Rotor Synchronous Machine: Torque in Round Rotor Synchronous Machine - When the stator and rotor windings of a machine both carry currents, they produce their own magnetic…
Rotating Magnetic Field: Rotating Magnetic Field - It was seen earlier that the sinusoidal current in any phase of an ac winding produces a pulsating mmf wave in space whose…
Sinusoidally Distributed Current Sheet Concept: It was seen above that a distributed winding gives rise to a stepped mmf wave having a strong fundamental component which will be considered in…
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…
Synchronous Generator with Distributed Winding: Synchronous Generator with Distributed Winding - It may be seen from Eq. (5.7) that the flux/pole is limited by the machine dimensions and the peak…
EMF Equation of AC Winding: The B-wave of a EMF Equation of AC Winding synchronous machine (in general multi-polar) assumed sinusoidal is drawn in Fig. 5.15 and a single full-pitched…
2 Pole Elementary DC Machine: Figure 5.13 shows a 2 Pole Elementary DC Machine with a single coil rotating armature. It may be seen that the field winding is stationary…
