An actuator arrangement comprising:
- an epicyclic gear set including a sun gear;
- at least one planet gear in meshing engagement with the sun gear;
- a ring gear in meshing engagement with the planet gear, the planet gear being carried by a rotatable support, wherein one of the sun gear and the support is arranged to be driven by a motor and the other of the sun gear and the support is arranged to drive an actuator;
- and
- a clutch arrangement operable to resist rotation of the ring gear.
An actuator arrangement comprising:
- a motor operable to drive an actuator for movement, the motor being connected to the actuator by an actuator drive shaft;
- and
- stop means arranged to limit the range of movement of the actuator, the stop means comprising a stop element, a threaded element and a limit stops, wherein the threaded element is coupled to the actuator drive shaft, the stop element is engaged with the threaded element so as to move along the threaded element as the threaded element rotates, and the limit stops are arranged to limit the extent of movement of the stop element along the threaded element.
