What is the purpose of shaft in wind mill?
the purpose of drive shaft is to assist in the generation of electric power in the wind mill
There is a turbine in the wind mill. When the wind turns the blades on the wind mill, the generator inside cranks backwards createing power. The way it does this is that it turns a copper wire inside. One mill can create enough power for -currently- 90 homes. If there is alot of wind in that area that year.
