Abstract
An actuator () comprising a motor () assembly, a drive coupling () assembly and an actuator shaft (). The motor () assembly comprising a motor housing (), having a cover () and a base (); an electric motor (), comprising an external stator () and an internal rotor (); and a hollow output shaft () that is connected co-axially with the internal rotor () such that rotation of the internal rotor () causes a corresponding rotation of the hollow output shaft (). The driving coupling () assembly comprises a drive coupling housing () containing a drive coupling (), wherein the drive coupling () engages the hollow output shaft () such that rotation of the hollow output shaft () causes a corresponding rotation of the drive coupling (). The actuator shaft () extends through the hollow output shaft () and the internal rotor (), and engages the drive coupling () such that rotation of the drive coupling (), by the hollow output shaft (), causes the actuator shaft () to move axially.
