A rotor blade includes an actuator (1) comprising an electric motor (30) having a rotary drive shaft (31), a bearing (32) 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 (32). The lubrication system includes a sump (37) closer to the tip of the blade than the bearing (32), and a pump (38, 39) for pumping lubricant from the sump to the bearing.
