A rotor blade includes an actuator comprising an electric motor having a rotary drive shaft, a bearing for mounting the rotary drive shaft along an axis extending along the length of the rotor blade, and a lubrication system for lubricating the bearing. The lubrication system includes a sump closer to the tip of the blade than the bearing, and a pump for pumping lubricant from the sump to the bearing.
