Title: ELECTRIC ACTUATING DRIVE, AND ACTUATOR HAVING AN ELECTRIC ACTUATING DRIVE
Abstract:
The invention relates to an electric actuating drive for an actuator having a safety actuating function for setting an actuating element, such as a valve member, of a process-technical installation. The actuating drive comprises an electric motor for providing a torque for actuating the actuating element. The electric motor has a motor shaft for outputting the torque, an output shaft for transmitting the torque from the electric motor to the actuating element, and an in particular electromagnetic clutch and/or a clutch that decouples without power for providing and/or interrupting a torque-transmitting connection between the motor shaft and the output shaft. The output shaft, the motor shaft, and the clutch are arranged coaxially to one another.
