The synchronous motor itself does not have the ability to self-start.
The rotor is already rotating at synchronous speed due to continuous change in direction of rotor poles at a similar rate with stator. When voltage is applied on the stator current flows through it causing the production of rotating flux. Turn on the input three-phase voltage to the stator and the same produce RMF at synchronous speed. In order to start it the rotor is first started with the help of some DC motor and speed is increased until it reaches a synchronous speed of stator. For this damper windings are used. These windings behave as the rotor of an induction motor.

A Damper Winding consists of heavy copper bars inserted in the slots of the pole faces of the rotor as shown in the figure below. However you have to follow some certain procedure to avoid electrical and mechanical damage to the motor. When a three phase supply is connected to the stator the synchronous motor with Damper Winding.
Here is all you need to learn about how to make synchronous motor self starting Ans Three phase induction motor works on the principles of electromagnetic induction. Damper windings are additional windings consisting of copper bars placed in the slots in the pole faces. This is called an amortisseur or damper winding. Why three phase induction motor self starting but synchronous motor not etechnog different methods of starting synchronous motor synchronous motor an overview sciencedirect topics why synchronous motor is not self starting electric motor synchronous motors britannica working principle of a synchronous motor circuit globe This is the most used method of starting synchronous motorIn addition to the normal field winding an additional winding consisting of copper bars placed in the slots in the pole facesEnds of the copper bars are short circuited with the help of end ringsThis winding is called damper windingThis damper winding acts as a squirrel cage rotor of an induction motor.
