Abstract
The problem of providing a dual redundant load path which is not vulnerable to a single point failure at the output of a motor shaft is solved by a dual redundant load path motor system, particularly for use in aircraft actuation systems. A motor (22) has a rotor (34) extending entirely therethrough to define first and second output drives (38 and 40) at opposite ends (34a and 34b) of the rotor. First and second output shafts (46 and 48) are coupled to the opposite ends of the rotor. The output shafts are located at a common end of the motor, and one of the output shafts (48) is coupled through a connecting shaft (68) to the end of the rotor at the opposite end of the motor. The connecting shaft runs generally parallel to the rotor.
