Windenergieanlage mit einem Maschinenhaus

摘要

The turbine has a turbine house whose azimuth alignment is motorically adjusted by an adjusting device, where the device has a three-phase alternating current asynchronous motor (14) with a transmission (15) and a retaining brake formed by a brake disk (16) and brake pliers. A controller is arranged for limiting developing moment in the motor at a preset maximum value. The controller limits the torque, which is produced by the motor to a preset torque value that is smaller than or same as the maximum value.
