Patent ID: 7420288

Claim:
A wind turbine, comprising: a blade; an electrical power output device operatively connected to the blade, the electrical power output device having a plurality of windings, wherein the electrical power output device generates electricity when the blade rotates; and a controller for operating the electrical power output device at variable speed and for controlling power output from the wind turbine via aerodynamic stall; wherein operation of the wind turbine is controllable via increasing current based torque opposing operation of the wind turbine, the increasing current based torque including at least a control and reduction control, the control being selected from a group consisting of applying pulse width modulation to at least one of the plurality of windings of the electrical power out put device and shorting at least one of the plurality of winding of the electrical out put device via a shutdown switch, and the reluctant control being selected from a group consisting of applying pulse width modulation to at least one of the windings of the output device and shorting one of the plurality on winding output via shutdown switch.
