Synchrounous motor is three phase motor,but its not self
starting .why?
Answer Posted / sumesh sapkota
As per the operating principle of the Synchronous motor,
due to continuous & rapid rotation of stator poles,the
rotor is subjected to a torque which is rapidly reversing
i.e. in quick succession,the rotor is subjected to torque
which tends to move it first in one direction & then in the
opposite direction.Owing to its large inertia,the rotor
cannot instataneously respond to such quickly-reversing
torque,with the result that it remains stationary or in
other words it is not self starting.
