Explain the working principle of Synchronous Generator and
Assynchronous generator?
Answer Posted / prasanth kumar
The word synchronous suggests that the rotor shaft runs at
synchronous speed,Ns=120f/p.when dc supply is provided to
the rotor shaft,it starts rotating in synchronism thus
developing 3phase alternating voltage on stator winding
which s then taken out...
