摘要:
A multi-redundant motor (200) may be used to implement a relatively small, lightweight redundant actuator assembly package. The motor (200) is implemented as a brushless DC motor (200) and includes N-number of stators (202) and M-number of rotors (204). Each stator (202) has a plurality of independent stator coils (216) disposed thereon, and N is an integer greater than two. Each permanent magnet rotor (204) is disposed between, and is spaced axially apart from, two of the stators (202). Each rotor (204) has a plurality of magnetic dipoles (224) disposed thereon, and M is an integer equal to (N-1).
摘要:
An energy storage flywheel (106) system for a spacecraft is implemented with a fully redundant rotating group and gimbal actuator (324). In particular, the gimbal actuator (324), motor/generator (330), primary bearings (342), and secondary bearing actuator (354) are each implemented with a pair of redundant coils or motors.
摘要:
A flight control surface actuator assembly (120) includes a pair of flight control surface actuators (206, 208) and a pivot arm (212). One of the flight control surface actuators (208) is coupled to a flight control surface (202) and a static airframe structure (215), the other flight control surface actuator (206) is coupled to the flight control surface (202) and the pivot arm (212). The pivot arm (212) coupled to the static airframe structure (215) and is configured to pivot relative to the second flight control surface actuator (126) and the static airframe structure (215).
