Synchronous motor Three phase motor but it two winding
which are connected to rotor after 70% it'll be connected.
In the intial time Synchronour motor are not three Phase
but after about 70% speed it'll make Three phase. In the
starting Condiction, it is working as 2phase. it has zero
slip under usual operating conditions. Contrast this with
an induction motor, which must slip in order to produce
torque

Answer / vamsi

it does not having revolving field
because it works on 2 powersuplys ac & dc
