Rotork has been granted a patent for a motor-driven industrial actuator device. The device includes an enclosure housing a motor, control module, drive, battery pack, and temperature sensor. The control module charges the battery pack when an external power supply is present and the battery pack requires charging. During charging, the control module reduces the current to the battery pack if the measured temperature exceeds a predetermined threshold temperature, prolonging the battery pack’s life.

Patent granted for a motor driven industrial actuator device
A recently granted patent (Publication Number: US11742676B2) describes a motor-driven industrial actuator device with several innovative features. The device includes an actuator enclosure housing, an actuator motor in the form of a reversible electric motor, and a control module. It also features a drive with a shaft that connects the actuator motor to a valve or damper for actuation.
One notable aspect of the device is the inclusion of a battery pack housed within the actuator enclosure. This battery pack is electrically connected to selectively drive the actuator motor and can also be connected to an external power supply for charging. The control module is configured to receive data about the status of the external power supply and the charge state of the battery pack. If the external power supply is determined to be valid and present, and the battery pack requires charging, the control module will initiate the charging process.
The control module is also capable of operating in various modes, events, and actions, including battery actuation and self-contained modes, mains shutdown, battery shutdown, and battery actuation events. In the battery actuation mode, the control module uses the external power supply to charge the battery pack until it receives a move command. Once the move command is received, the control module activates the motor-driven industrial actuator device using power from the battery pack.
The patent also mentions the inclusion of temperature sensing devices associated with the battery pack. The control module can receive data about the measured temperature and compare it with predetermined threshold temperatures. If the measured temperature exceeds the threshold, the control module will reduce the charging current from the external power supply to prolong the life of the battery pack.
Additionally, the device may include ancillary systems such as sensors and transducers connected to a remote location for monitoring process conditions and reporting data. The external power supply can run these ancillary systems, and the battery pack can selectively drive the actuator motor while also running the ancillary systems.
Overall, this patent describes a motor-driven industrial actuator device with advanced features such as a battery pack, temperature sensing, and ancillary systems. These innovations aim to improve the functionality and efficiency of actuator devices in industrial settings.
