Abstract: A modular skid assembly is disclosed. The modular skid assembly includes a skeletal framework configured to house electrical equipment components and support power cables routed between the electrical equipment components, wherein the skeletal framework is configured to house electrical components in two parallel rows with an aisle between the two parallel rows, the skeletal framework including an upper superstructure, a lower superstructure, and one or more vertical columns connected between the upper superstructure and the lower superstructure. The upper superstructure includes a first horizontal support and a second horizontal support. The upper superstructure includes a lower cable tray having a plurality of tray supports fixed to at least one of the first horizontal support and the second horizontal support and extending over the aisle from the first horizontal support towards the second horizontal support.

Abstract: A carbon-segment face commutator assembly for an electric motor includes an annular array of copper conductor sections stamped from a single copper blank. The annular array is overmolded with an electrical-conducting resin-bonded carbon composition which mechanically interlocks the conductor sections and defines a circular commutating surface. During overmolding, radial grooves are formed in a bottom surface of the carbon overmold opposite the commutating surface. An annular hub is then formed by overmolding an insulator material around and under the carbon overmold and the conductor section array. The hub insulator material flows into the radial grooves of the carbon overmold and leaves only the circular commutating surface exposed. The carbon overmold is formed into an annular array of eight electrically-isolated carbon segments by machining radial slots inward from the commutating surface of the carbon overmold to the underlying radial grooves.
