    • The invention relates to a pitch drive device (10) capable of emergency operation for adjusting a rotor blade pitch of a wind or water power plant. The pitch drive device (10) comprises an inverter device (14) and a three-phase current drive motor. The drive motor is implemented as a three-phase IPM synchronous motor (12) (Interior Permanent Magnet). A direct current power storage device (20) can advantageously be substantially directly connected to an intermediate direct current circuit (18), at least for emergency operation, between a rectifier device (16) and the inverter device (14) for at least briefly supplying power to the synchronous motor (12), so that the IPM synchronous motor (12) can be operated at least briefly under speed control when the intermediate circuit voltage UZK is falling. The invention 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, for example, improve the efficiency as an energy buffer, and reduce current transfer via the rotor slip ring.
