The multi-rotor vertical axis wind turbine includes a plurality of vertical wind rotors rotatably mounted on support arms extending from the vertices of upper and lower polygonal frame members. The upper end of each rotor is journaled into a plain bearing, and a lower portion is journaled into a freewheeling clutch bearing. A pulley wheel is mounted on the lower end of each rotor. A generator is centrally located beneath the lower frame member and has a rotatable armature shaft extending vertically upward. The pulley wheel of each vertical rotor is connected to the armature shaft by its own separate endless belt.

A system for generating power from turbine arrays comprises a plurality of turbines positioned in a turbine array. Each turbine comprises a vertical shaft having an upper portion, a middle portion and a lower portion. The lower portion of the shaft is attached to a base member housing at a top portion thereof utilizing a lower shaft bearing. Thus, the shaft is configured to rotate and move linearly in an axial direction. Each turbine further comprises a turbine head having blades mounted at the upper portion of the shaft utilizing an upper shaft bearing and a first pulley coupled with a gear connected to the middle portion of the shaft. The system further comprises a generator having a second pulley that is engaged with the first pulley utilizing a coupling means. When the shaft rotates, the first and second pulleys turn to actuate the generator thereby generating electrical current.

This system includes a belt drive system for a wind turbine generator comprising: a tower having a wind turbine wheel rotatably attached to the tower; a generator platform attached to the tower; a generator supported by the generator platform; and, a turbine drive belt adapted to engaged with the wind turbine wheel and the generator to transfer rotational energy from the wind turbine wheel to the generator to generate electricity.

A vertical turbine comprising a blade control mechanism including a sun gear engaging a plurality of planetary gears each coupled to blade assemblies. The sun gear has at least half circumference of its teeth removed, as the turbine receives maximum downstream torque in the circumference with teeth and it leaves blades free to rotate in the circumference without teeth for minimum upstream drag. The turbine converts the rotational blades into parallel movement and unidirectional propulsion with minimum turbulence.

A generator module and a wind turbine having the same are provided according to the present application. The generator module includes a generator module housing, a generator unit and a generator rotating shaft.
