The Vestas V90-3MW is a three bladed upwind wind turbine generator that uses pitch control and a doubly fed induction generator (50 Hz version). Vestas has installed over 500 units of this type globally since launch.
The V90-3MW evolved from the V80, but with a number of radical differences, the main one being that an oil cooled generator was used, and a single supplier (Hansen) was used for a new style compact gearbox which now butted up directly to the hub rather than through a low speed shaft.
Its relatively low overall weight was one of its major selling points, with Vestas marketing the turbine as giving 50% more power for roughly the same weight as the V80. The V90-3MW should not be confused with the V90-2MW which is essentially a V80-2MW with longer blades.
It is produced in both an on and offshore version.
