Hi, I need help with these questions of Electric machines?

1º When a synchronous motor is used, despite its constant speed characteristic not being used?

Why can't a synchronous motor start by itself?

3º What techniques can be used to start a synchronous motor?

4º What are the damping windings? Because they produce a unidirectional torque at start-up, while the torque that produces the field winding changes direction?

5º  What is a synchronous capacitor? What is it used for?

6ºExplain by fasorial diagrams what happens to a synchronous motor as its field current varies, from the phasor diagram obtain the V curve of the synchronous motor?
