I am not sure what the characteristics of a salient synchronous machine are? What does it mean if a synchronous machine is salient and how does it differentiate from a non salient one?

I have read up on this but always the info has been vague, please can someone explain.

 

Do you mean salient and non-salient pole synchronous motors?

 

Or perhaps salient pole synchronous generators?

 

Salient pole synchronous generators.
