Medium speed wind turbine generator coupled to, and sharing components with a planetary style gearbox with a ratio between 13:1 and 35:1. This technology reduces overall turbine cost and weight while significantly increases efficiency and reliability.

arious power transmission and generation systems and assemblies are provided for a wind turbine. In one embodiment, a power generation system is provided including a transmission having an input axially aligned with an output, the input configured to receive rotary motion generated by a wind driven rotor head, the input located downwind of the output, an electromagnetic apparatus having an input configured to be coupled to the transmission output, and a bearing configured to radially support… Show more
