    Abstract: The invention relates to a blade pitch controlling drive for a wind turbine, comprising an electrical converter, an electric motor that is electrically coupled to the converter, a monitoring unit operable to monitor an electric output current supplied by the converter to the electric motor and determine a state of the load on the converter as a function of the electrical output current, a current limiting unit operable to reduce a maximum possible output current to a nominal current when the state of the load is an overload state when the nominal current when in a non-overload state, and a peak current control unit that can be activated. When activated, the peak current may be provided as the maximum possible output current, regardless of the load state of the inverter at the time of the activation.

    Abstract: An electric drive has at least one electric motor and a power converter feeding electrical motor current thereto. A current desired-value emitter generates a reference signal. An additional circuit is coupled to the current desired-value emitter so as to receive the reference signal and generates a current desired-value signal. A current regulator is coupled to the additional circuit so as to receive the current desired-value signal. The current regulator generates a control signal to the power converter so as to regulate the motor current as a function of the current desired-value signal. The additional circuit has a first mode wherein the current desired-value signal corresponds to the reference signal and a second mode wherein the current desired-value signal is a pulsed signal.

    Abstract: A pitch system for a wind turbine installation having an electrically driven pitch drive associated with each rotor blade and an electric motor arranged in a rotating part of the wind turbine installation for blade adjustments. A power and control unit is associated with the motor and has line connections for the transmission of power and control data from the power and control unit to the motor and vice versa. The line connections are passed via a first rotating bushing arranged at a connecting point between the rotating part and an axially adjacent stationary region. The pitch system also includes second rotating bushing which operates mechanically and electrically separately from the first rotating bushing and is connectable to the power and control unit and to the motor for maintaining reliable transmission of the power and control data if the first rotating bushing fails.
