Abstract
A multi-slice electromechanical hinge-line rotary actuator includes a motor stator configured to generate rotational motion about a rotational axis. The multi-slice electromechanical hinge-line rotary actuator further includes a plurality of layers rotatably coupled to the motor stator. Each layer includes an output arm slice configured to rotate about the rotational axis in response to the rotational motion.
Claims8
A multi-slice electromechanical hinge-line rotary actuator comprising:
- a motor stator magnetically coupled to a motor rotor that rotates about a rotational axis, the motor stator magnetically configured to generate rotational motion about a rotational axis;
- and
- a plurality of layers rotatably coupled to the motor stator via a roller bearing assembly that is rotatably coupled to the rotor via a roller bearing assembly, each layer including an output arm slice receiving a rotational drive force transferred by the roller bearing assembly such that each output arm slice rotates about the rotational axis in response to the rotational motion.
