Abstract
An electrically operated actuator (10) for a slidable door of a motor vehicle comprising a planetary gear set (12) including a sun gear (22), a number of pinion gears (24) rotatably mounted on a planet carrier (26) and interengaging with the sun gear, and a ring gear (28) interengaging with the pinion gears, the sun gear, planet carrier and ring gear being rotatable about an axis (A); an electric motor (14) connected to the planet carrier to rotate the planet carrier about the axis; an electrically actuated brake (16) connected to the sun gear to brake rotation of the sun gear about the axis; a cable drum (18) rotatably driven by the ring gear; and a cable (20) wound around the cable drum and connectable to the slidable door. Allows a reduction in overall dimensions of the actuator.
