Maximum output voltage of the AC generator = N×A×B×ω, where N is number of turns, A area of coil, B is magnetic field and ω is angular speed 
 
ω = 2πν, where ν is frequency of rotation.
 
(1) if the speed of rotation is doubled, frequency of rotation will be doubled
(2) if the speed of rotation is doubled, maximum output voltage also doubled.
