摘要：
A wind power plant is characterized in that a measurement device (18) is provided for the determination of the load on an electric motor (13, 14), wherein the control device (16, 17) reduces the load on the motor (13, 14) by reducing the rotational speed of the rotor (11), by changing the blade angle of the at least one rotor blade (12, 12′) and/or by reducing the output of the wind power plant (10) when a preselectable first load limit of the electric motor (13, 14) is exceeded.
