They are generally used in lower speed electrical machines,say 100 RPM to 1500 RPM .As the rotor speed is lower ,more number of poles are required to attain the required frequency .(Ns=120f/P there fore ,f = Ns*p/120 ie frequency is proportional to number of poles).Typically number of salient poles is between 4 to 60. Flux distribution is relatively poor than non-salient pole rotor hence the generated emf wave form is not as good as cylindrical rotor .

Salient pole rotors generally need damper winding to prevent rotor oscillations during operation. Salient pole synchronous generation are mostly used in hydro power plant.
