Abstract: A motor assembly comprises a plurality of redundant bearings, a plurality of coaxial support elements, with at least one of the support elements rotatable about an axis of rotation, and an armature rotatably guided by the plurality of support elements to rotate about the axis of rotation. The bearings provide redundancy to continue armature rotation in the event one bearing fails.

Abstract: A printed circuit board assembly mounting system comprises a chassis support having at least one keyhole. The keyhole is adapted to receive a mounting post coupled to a printed circuit board assembly. The chassis support further comprises at least one guide adapted to align the mounting post with the keyhole. The mounting post is adapted to slidably engage the keyhole to secure the printed circuit board assembly to the chassis support.

Abstract: A charging system employing a liquid-cooled transmission cable for transferring power. The transmission cable has a central tube with an extruded member disposed therewithin for carrying coolant. A plurality of layers of coaxial tubular wire braid are disposed around the central tube that carry charging current and that are separated by a layers of dielectric material. An outer layer of wire braid is disposed around an outermost layer of dielectric material that is used for grounding and/or shielding. An outer jacket is disposed around the outer layer of wire braid for encasing the transmission cable. The extruded member may comprise a thermoplastic rubber extrusion, for example. The coolant path through the transmission cable is internally supported by means of the extruded member to assure uniform flexibility, maintain tangential magnetic flux, and eliminate kinking and collapse of the flow path.
