    摘要: An activation circuit and a method for operating an activation circuit for a DC motor having an electrically actuated stopping brake, in particular for adjusting a rotor blade of a wind or water power facility. The activation circuit includes an emergency operation supply unit and a three-phase bridge inverter. The emergency operation supply unit is connected so it is disconnectable via an emergency operation network switching element to the intermediate circuit of the three-phase bridge inverter, the DC motor is connected via an emergency operation motor changeover element either to the three-phase bridge inverter or to the emergency operation supply unit, and the stopping brake is connected via an emergency operation brake changeover element either to the three-phase bridge inverter or to the emergency operation supply unit.

    摘要: A pitch drive device capable of emergency operation by adjusting the rotor blade pitch of a wind or water power plant. The pitch drive device includes an inverter device and a three-phase current drive motor preferably a three-phase IPM synchronous motor. A direct current power storage device can be substantially directly connected to an intermediate direct current circuit, at least for emergency operation, between a rectifier device and the inverter device for at least briefly supplying power to the synchronous motor, so that the IPM synchronous motor can be operated under speed control when the intermediate circuit voltage UZK is falling. The device enables speed-controlled emergency operation of the pitch drive device at high torque when an intermediate circuit voltage UZK is falling in emergency operation, wherein the direct current energy storage device can, improve the efficiency as an energy buffer, and reduce current transfer via the rotor slip ring.
