Abstract: An electric motor includes a rotor and a stator formed by a plurality of stator phases. The stator phases include coils that extend fully about the motor axis of the motor. The stator phases further includes flux rings disposed on opposite axial sides of the coil and that are joined by axial returns. The stator phases electromagnetically drive rotation of the rotor on the motor axis. Stator segments are formed by one or more stator phases grouped together. Rotor segments are formed by one or more rotor phases grouped together. Motor segments are formed by one or more stator segments and one or more associated rotor segments. Motor segments are stacked along a shaft to form the electric motor.

Abstract: A fluid moving apparatus includes an electric motor having a rotor and a stator and a propeller. The rotor rotates relative to the stator on an axis to generate a rotational output. The rotational output is provided to the propeller to power the marine propulsion apparatus. The stator includes one or more coils configured to power rotation of the rotor. The one or more coils extend circumferentially around and can be coaxial on the axis. A portion of a housing of the motor extends into the aquatic environment to facilitate heat dissipation.

Abstract: Automated dynamic manufacturing systems may provide for alignment of multiple components with respect to one another, such as an apparatus, a robot, and a supply of parts. The alignment may initially be performed roughly, using a global metrology device configured to track the apparatus, robot, and supply of parts, each of which may be movable with respect to the others, such as by being positioned on a respective automated guided vehicle. Alignment may then be performed to closer tolerances using a local metrology device coupled to the robot and configured to accurately position an end effector, such that the end effector may perform a manufacturing task on the apparatus, such as a pick-and-place process involving transporting an individual part from the supply of parts, transferring it to the apparatus, and coupling it thereto. Such systems and methods may be used to perform manufacturing processes on large apparatus, such as aircraft.

Abstract: A method and apparatus for bending an elongate member. A plastic force may be applied to the elongate member. The plastic force may be configured to cause the elongate member to bend with a plastic deformation. The plastic force may be reduced to an elastic force that is applied to the elongate member after the plastic force causes the elongate member to bend with the plastic deformation.

Abstract: Techniques for ultrasonic determination of the interfacial relationship of multi-component systems are discussed. In implementations, a laser energy source may be used to excite a multi-component system including a first component and a second component at least in partial contact with the first component. Vibrations resulting from the excitation may be detected for correlation with a resonance pattern indicating if discontinuity exists at the interface of the first and second components.
