ok actually i am looking for the answer also but this is what i have got so far,you can understand cylindrical rotor in comparison to Salient pole machines. In cylindrical rotor, as it rotates, the air gap between the rotor and stator doesnt change due to its cylindrical shape, but for salient pole machine, due to its shap, the air gap changes as it rotates, due to those dents(laminations) and since air gap is fixed for cylindrical rotor,the magnetic path reluctance is independent in respect to its position to magnetic poles
The speed of the machine is tied to the power supply frequency and the number of poles the machine has. It becomes impractical to make a round rotor machine with many poles, so machines that spin at low revolutions will typically be salient designs. A two or four pole machine could be round rotor designs.

A flying machine with a rotor an a propeller is a helicopter
The word rotor is used to refer to a rotating part of a machine. It is also a palindrome.
a ROTOR is basically any part of a machine that rotates. eg the armature in a motor a STATOR is the part of a machine that is stationary. ie the ROTOR revolves within the STATOR
The rotor will have to be removed from the car. It can be resurfaced by mounting it on a special machine that slowly removes metal from the rotor until the rotor is smooth.
It could be Composite Rotor Blade OR Cylindrical Roller Bearing
That is to stabilise the inherent spin of the main rotor and to steer the machine.
Smooth cylindrical type
Rotor is a palindrome for a machine that turns or rotates.
A helicopter.
That's called a 'lathe'.
