Electric Machines
Principle of operation of synchronous machines Alternators. When DC voltage is applied to the rotor, it becomes an electromagnet. If the rotor is driven by a prime mover, a relative motion happens between the rotor magnetic flux and the stator conductor. Therefore according to faraday's law, an EMF is induced in the stator winding.
