A linear actuator 110 includes a planetary gear system 114 including a sun gear 136, a ring gear 138, and a planet carrier 132. A linear output mechanism 122 is coupled to the planetary gear system 114. A first motor 112 is configured to drive a first input shaft 116, and the first input shaft 116 is coupled to the planet carrier 132. A second motor 118 is configured to drive a second input shaft 120, and the second input shaft 120 is coupled to one of the sun gear 136 and the ring gear 138. |
