Wind Power Generation ScienceDirect

Abstract The drive train connects the energy capturing rotor of a wind turbine to the generator which produces the unit s electrical power Large wind turbine rotors rotate at around 20 rpm but conventional generators rotate much faster so there will often be a gearbox between the rotor and the generator to match the speed of one to the other
