The generator has elements extremely relevant to its operation in a suitable way, such as the rotor, referring to the rotating part of the machine. It can consist of a package of sheets of ferromagnetic material held in a winding formed by copper conductors, called field winding, with the function of generating a constant magnetic field, in the same way as in the case of the direct current generator to interact with the field produced by the stator winding.
It is important to note that its synchronous name is due to the fact that this machine is capable of operating with a constant speed of rotation synchronized with the frequency of the alternating electric voltage applied to its terminals. This means that, due to the rotational movement between the rotating field and the rotor, it is known as a synchronous machine, since it must be taken into account that it promotes synchronism between the stator and rotor fields. In this way, this generator is considered one of the most important types of rotary electric machines, allowing the conversion of energy when operated as a generator or as a motor. https://www.mrosupply.com/pumps/centrifugal-pumps/2984144_2wf1018_bell-gossett/
