摘要： A method of adjusting a yaw angle of a wind turbine. The wind turbine includes a nacelle that is rotatably coupled to a tower. The method includes coupling a yaw drive assembly to the nacelle for adjusting an orientation of the nacelle with respect to a direction of wind. A first sensor that is coupled to the wind turbine transmits at least a first monitoring signal that is indicative of an operating condition of the wind turbine to a control system. A yaw angle of the nacelle with respect to the direction of wind is calculated by the control system based at least in part on the first monitoring signal. The yaw drives assembly is operated to adjust a yaw of the nacelle based at least in part on the calculated yaw angle.

摘要： In a method for operating a vehicle which has a first axle, a second axle, a unit for determining slipping of at least one wheel of the second axle on a ground surface, and a braking device associated with the wheel, a drive torque is applied to the first axle and the second axle via a central differential, and, in the event of slipping of the wheel, a braking torque required to prevent the slipping being determined. A setpoint braking torque is set on the braking device, which is less than the required braking torque, and the part of the drive torque supplied to the first axle is increased.

摘要： An axial fan, having an inner electric motor and a fan wheel connected to the electric motor so as to rotate with it and has a plurality of wheel blades defining a blade length and extend outwardly from the electric motor. A fan housing surrounds the fan wheel. The fan housing is connected to the motor via holding struts which extend to the outside from the motor to the fan housing. A motor housing is provided on the motor behind the fan wheel and accommodates a motor electronics system. A flow duct having an inflow opening and an outflow opening is fastened to the motor behind the fan wheel such that the inflow opening is arranged offset to the outside with respect to the outflow opening. The outflow opening is oriented in such a way that an air flow which exits the outlet opening is guided onto the motor housing.
