WebDec 2, 2024 · In a synchronous generator, a DC current is applied to the rotor winding, which produces a rotor magnetic field. The rotor of the generator is then turned by a prime mover, producing a rotating magnetic field within the machine. This rotating magnetic field induces a three-phase set of voltages within the stator windings of the generator. Two ... The excitation is often 208/240-V 3-phase mains power. Many synchros operate on 30 to 60 V AC also. Synchro transmitters are as described, but 50- and 60-Hz synchro receivers require rotary dampers to keep their shafts from oscillating when not loaded (as with dials) or lightly loaded in high-accuracy applications.
