Abstract:
A pitch drive device for a wind power or hydroelectric power station having a synchronous motor and a motor operation switchover unit for switching between a normal operation and emergency operation modes. To do so, the synchronous motor is operable in normal operation with three-phase AC and in emergency operation with DC. A method for operating a pitch drive device of this type is also disclosed.
