No.
In synchronous generator or motor we cannot use ac voltage
for field winding.
Synchronous generator/motor works on magnetic locking
principle hence we have to create constant magnetic poles
on rotors.
In case of generator these magnetic pole create voltage in
stator winding as per the speed of rotar.
And in case of motor these magnetic poles gets lock with
stator rotating magnetic field.
