摘要： The present invention describes a motor driven actuator device comprising an actuator motor; a control module; an input for receiving an external power supply; and a battery pack. The battery pack is electrically connected to selectively drive the actuator motor, and is electrically connectable to the external power supply for charging. During charging of the battery pack, the control module is configured to: receive data representative of the measured charge level of the battery pack; compare the measured charge level with a pre-determined charge level required to complete at least two battery shutdown events under battery power alone, wherein a battery shutdown event involves moving the actuator device to a failsafe position; and, if the measured charge level is equal to or greater than the pre-determined charge level, indicate the battery status to other internal components associated with the actuator device. During subsequent actuator device operation, the control module is configured to: detect and determine the validity of the external power supply, and if the external power supply is determined to be invalid, instruct a battery shutdown event causing the battery to be discharged, such that there will still be enough charge in the battery to complete at least one further battery shutdown event; and, subsequently detect when the external power supply becomes valid, and resume actuator device operation under the external power supply, whilst simultaneously recharging the battery pack to at least the pre-determined charge level.

摘要： An actuator driven by an electric motor of the polyphase or single phase induction type has a stator with power windings as well as a rotor. At least one fixed fluxed sensor independent of the power windings is provided. The at least one sensor is arranged in an air gap between the stator and the rotor of the induction type motor such that the voltages induced in the at least one sensor represent a measure of the magnetic flux existing in the air gap. The flux sensor which is a preferably sensing winding provides a flux signal. An output signal representing the instantaneous output torque of the motor is generated by multiplying the flux signal by the electric current flowing through one or more of the stator power windings.

摘要： A valve actuator has an electric driving motor for driving an output shaft through reduction gearing and a manual operator for driving the output shaft manually. A drive transfer device for transferring the drive from the electric motor to the manual operating means incorporates an electric switch which is operated by the initial movement of a manual operator of the drive transfer device to cause the motor if rotating to be brought to a stop. Continued movement of the manual operator causes the drive transfer device to transfer the drive to the output shaft from the electric motor to the manual operator. The drive transfer device advantageously includes a clutch between the motor shaft and a worm shaft forming part of the reduction gear. The driven clutch member may form an integral part of a unit which is slidable as a sleeve along the worm shaft but is keyed for rotation to the worm shaft, the unit also having a pinion for meshing with a drive gear forming part of the hand drive.

摘要： A piston-cylinder type actuator is provided with a fail-safe unit for returning the piston 10 to a fail-safe position in the event of failure of the power supply to the cylinder 12. The fail-safe device comprises a housing unit 27 which is detachably connected to the casing 18 of the actuator. The housing contains a pre-loaded spring 30 acting between the closed end 29 of the housing and a movable cap member 31 which is engaged by the piston rod 17. The cap member is retained in the housing by a fixed ring 32 which is connected to a flange 38 of the actuator. Removal of the fail-safe unit is prevented unless the piston is in its fail-safe position by means of a bayonet-type fitting comprising lugs 35 on the housing which are axially and rotatably engaged with locking recesses on the remote surface of the adaptor flange 38.
