Rotor (of a wind-power generator)
The part rotated by the wind to produce power, and comprising the blades and the hub or hubs to which they are attached.
Note: The term propellor (abbreviated as prop) is sometimes used for a rotor in which a few blades are radially disposed about a hub and for which the normal axis of rotation is horizontal, or nearly so.
Please note that this is the term as it stands in the original IALA Dictionary edition (1970-1989)
