What is the meaning of 'A synchronous motor floating on
line'?
Answer Posted / abysen
when a synchronous machine operates at no load,Ia=0,therefore Fa=0.Neglecting the leakage impedance,then Ff=Fr & Ef=Er=Vt.Under this condition the machine is neither in motoring nor in generating mode.This condition is called Floating on the line.
Fa=mmf due to arm current
Fr=air gap mmf,Ff=field mmf,Ef=excitation emf,Er =air gap emf.
