What is a measure of a synchronous coefficient A. Ability to operate with the force to push it out of the synchronism mathematically B. Oppose the force to pull it out of synchronism mathematically C,. Ability to oppose the force that tend to pull it out of synchronism D. Abilty to oppose the force that tend to push it out of synchronism For a silent pole machine, by how much does the armature current lacks the induced emf. A. 90 degrees B. 0 degrees C. -45 degrees D. A and B
Synchronous Generator
In comparison to an asynchronous generator, it is a machine where the rotor speed is equal to the rotating magnetic field produced by the stator, i.e., mechanical speed is equal to the electrical speed, thus called synchronous, and not asynchronous.
Salient Pole Rotor
Salient pole rotor includes a large number of exposed poles mounted on a magnetic wheel. The construction of a bright pole is as shown in the image on the left. The proposed poles are made of metal laminations. The rotor winding is provided on these poles and is supported by pole shoes.
