Claim 6:
7. A wind turbine comprising:
a drive device including a plurality of actuators configured to cooperate with each other;
a wind turbine body including a moving part configured to be driven by the drive device; and
a condition monitoring device for the drive device of the wind turbine, the condition monitoring device including:
one or more sensors, the one or more sensors operatively connected to the drive device of the wind turbine and configured to sense information relating to a load applied to each of the plurality of actuators;
a controller having a processor, the controller operatively connected to the drive device of the wind turbine and the one or more sensors, the controller being configured to:
obtain the information relating to a load applied to each of the plurality of actuators;
based on the obtained information, calculate a partial load ratio, the partial load ratio representing a ratio of a load on each of the plurality of actuators to a total load, the total load being a sum of the loads on the plurality of actuators;
diagnose a condition of the drive device based on the partial load ratio; and
control the drive device based on the diagnosed condition.
