Patent ID: 8084876

Claim:
A wind turbine for generating electric power, comprising a generator ( 105 ) and a wind turbine rotor ( 101 ) for driving the generator ( 105 ), wherein the generator ( 105 ) comprises: a generator stator ( 201 ) comprising at least two stator poles ( 203 ), wherein each stator pole ( 203 ) is provided with windings ( 204 ) of wire, wherein at least part of the generator stator ( 201 ) contains metal having directional magnetic properties, and wherein an outer diameter of the generator stator ( 201 ) is between 1 and 4 meters; a generator rotor ( 210 ) comprising at least two magnetic components ( 211 ); and a stator ring ( 220 ) comprising a plurality of stator-ring sections ( 221 ); wherein said generator ( 105 ) is connected to the wind turbine rotor ( 101 ) via a gearbox ( 103 ), wherein the gearbox ( 103 ) during operation of the wind turbine increases the rotational speed of the generator ( 105 ) in comparison with the rotational speed of the wind turbine rotor ( 101 ), between 2 and 15 times; and the generator ( 105 ) is a medium speed generator having a rotational speed during operation within 30-1000 RPM.
