Abstract

A wind turbine is provided that minimizes the size of the drive train and nacelle (14) while maintaining the power electronics and' trans former ( 30 ) at the top of the tower. The turbine includes a direct drive generator (20) having an integrated disk brake ( 50) positioned radially inside the s tator while minimizing the potential f or contamination. The turbine further includes a means f or mounting a transformer ( 30 ) below the nacelle wi thin the tower. Futhentiore the bearing system comprises a double -tapered roller bearing (38) and a cylindrical roller bearing (40 )
