发明名称 WIND POWER INSTALLATION WITH AN ASYNCHRONOUS MACHINE FOR ESTABLISHING THE AZIMUTH POSITION
摘要 An asynchronous machine has a first rotor/stator arrangement in which the rotor is connected to a shaft, and a method of controlling such an asynchronous machine is provided. A drive is provided which permits nullification of the play of the mechanical components in the predetermined target position without involving mutual influencing as between the desired braking moment and elimination of the play. A suitable method of controlling a drive is provided. An asynchronous machine has a first rotor/stator arrangement in which the rotor is connected to a shaft, characterized by at least one second rotor/stator arrangement which however is electrically separated from the first rotor/stator arrangement, wherein the rotor of the second rotor/stator arrangement is also connected to the shaft.
