The induced emf in a
pole, 3-phase star connected synchronous motor is considered to be equal and in phase with the terminal voltage under no load condition. On application of a mechanical load, the induced emf phasor is deflected by an angle of
mechanical with respect to the terminal voltage phasor. If the synchronous reactance is
, and stator resistance is negligible, then the motor armature current magnitude, in ampere, during loaded condition is closest to, _________ (round off to two decimal places).
