Answer / vikas mudhai

silent pole rotor-
1)used in low speed alternators(hydro-generator)
2)more no. of poles(4 to 64)
3)large diameter & small axial length

non-silent pole rotor-
1)used in high speed alternators(turbo-generator)
2)less no. of poles
3)small diameter & long axial length

Answer / k.prakashchandra

salient means most noticeable.So in salient pole rotor the
poles are seen distinctly and in the other type you don't
see the shape of the poles and the rotor has smooth surface

Answer / ramesh behera

Silent pole rotor-

1)large in diameter small in axial length
2)where flux density are high so lows speed alternators are
used for generating electrical energy.
3)Arrangement of large pole such to max 64
4) so these type pole rotors are used in hydro-generator

Non-silent pole rotor-
1)small in diameter large in axial length
2)Flux density appx. low high speed alternator are used
generating electrical energy.
3)No pole field are less appx.=4
4)so these type pole rotors are used in turbo-generator
