In the AC Machine article, we examined a simple permanent-magnet AC machine. That machine used a rotating armature coil, which means the power to run the motor or the power from the generator must be transmitted through the brushes and slip rings. For large machines, that is not very efficient, so AC synchronous machines are built with the armature on the stator and the …

What is a Synchronous Generator? A synchronous generator is an ac generator in which the output is synchronized to the position of the rotor. The frequency of the voltage produced by the synchronous generator depends only on the speed at which its shaft is turned and the number of poles it has. This makes the synchronous generator very efficient for producing electrical …
