Answer Posted / pooja vanan
in synchronous motor due to continuous and rapid rotation of
stator poles, the rotor is subjected to a torque which is
rapidly reversing and tends to move it first in one
direction and then in the opposite direction .owing to its
large inertia the rotor cannot instantaneously respond to
such quickly reversing torgue with the result that it
remains stationary i.e it is not self starting
