B)d.c. excitation only
C)both the speed and rotor flux
D)none of the above

Question

Quizplus · Accepted Answer

The magnitude of stator back e.m.f. (Eb) in a synchronous motor primarily depends on the d.c. excitation of the motor, as it directly influences the magnetic field strength and thus the induced e.m.f.
