High speed alternators usually have
Salient pole rotor
Cylindrical rotor
Both salient pole and cylindrical rotor
None of the above
Cylindrical rotor
The
cylindrical motors have small diameter and are longer in length as compared to
salient pole motor. Thus, cylindrical rotors are used for high speed turbo
alternators.
Hence, the correct option is (B).
&Key Points:-
Salient
pole rotors are used for low speed rotors.
