A wind driven generator with counter-rotating armature and rotor is disclosed. In a first embodiment a rotor having magnets mounted thereon and an armature having windings disposed thereon are both coaxially mounted about a hollow pole. The hollow pole provides the structural support for maintaining the generator in a vertical attitude. Bearings are situated between the armature and pole, and between the rotor and the pole. A commutator and brushes is employed to conduct the power signal generated in the windings to electrical device. In a second embodiment, a rotor and armature are disposed about and rotatably mounted on a hollow pole as in the first embodiment with the hollow pole coaxially situated over a second vertical pole. The hollow pole is sized for sufficient clearance to allow the hollow pole to slide vertically on the second pole. A pulley and cable mechanism is employed so that the hollow pole and generator attached thereto may be easily raised for operation in higher velocity winds yet readily lowered for servicing and maintenance thereof.
