Direct Liquid Cooling for an Outer-Rotor, Direct

The major shortcoming to traditional high-powered direct-drive generators is extraordinary size direct-drive wind turbine generators, where mass must be kept reasonably low. Currently, wind

Direct drive technology

With turbine power outputs ranging from 500kW to 1MW, and rotor tip heights from 61 m to 100 m, our DIRECTWIND turbines are designed to deliver maximum wind energy yield and a low total cost of electricity for all types of wind

Design of 20 MW direct‐drive permanent magnet synchronous generators

Considering the drivetrain configuration, high-power wind turbines could be roughly classified into geared and direct drive (DD) types. Also, compared with the geared type, the high-power wind
