Abstract: An interlock system and method are provided for protecting high voltage electrical couplings. The interlock system may control access to the electrical couplings based on the voltage of the electrical couplings. The interlock system may also selectively energize and de-energize the electrical couplings based on the position of a lid.

Abstract: A buss bar assembly for a multiphase electrical machine, including a substantially annular dielectric housing having a central axis, a plurality of dielectric phase bar mounting members located within the housing, and a plurality of electrically conductive phase bars. The phase bars are disposed in the housing and substantially surround the central axis. Each phase bar has opposing, substantially planar axial sides and is in engagement with at least one phase bar mounting member. An axial side of each phase bar is in superposition with an axial side of another phase bar whereby the plurality of phase bars are axially stacked along the central axis. The phase bars have mutually spaced positions relative to each other in directions along the central axis, these positions defined by the phase bar mounting members whereby the phase bars are electrically isolated from each other within the housing.

Abstract: A buss bar assembly for a multiphase electric machine. The buss bar assembly includes a substantially annular dielectric housing having a central axis. A plurality of dielectric mounting members is located within the housing. A buss bar plate assembly is disposed in the housing, and in engagement with the mounting members. The buss bar plate assembly includes a substantially planar dielectric substrate that has opposing, substantially planar axial sides, and substantially surrounds the central axis. The buss bar plate assembly also includes a plurality of electrically conductive phase bars applied to at least one of the opposing substrate sides. Each phase bar is for electrical connection to a different one of multiple electrical phases and substantially surrounds the central axis, with the phase bars being electrically isolated from each other within the housing.

Abstract: A stator assembly of an electric machine includes a segmented lamination stack formed of an interconnected series of lamination segment stacks, and a plurality of coil isolators each having a conductor wound thereon, each having a radially outward interlock at each circumferential end thereof, and each having a radially inward interlock at each circumferential end thereof, the coil isolators being serially connected by the interlocks to form a cavity closed down the axial length of the stator assembly, the coil isolators electrically insulating the lamination segments from the conductors.

Abstract: A terminal block holder is provided for securing a terminal block assembly having at least three conductive bus bars enclosed within corresponding individual insulating columns passing through a housing of an electric machine, the terminal block holder including a plate defining at least three openings therein, and including first and second dividers extending from the plate and respectively separating different adjacent ones of the openings, where the plate is adapted to abut the terminal block assembly in a first direction, where the plate is adapted to abut the housing in a second direction, where the dividers are adapted to abut the terminal block assembly in a third direction, and where the first, second and third directions are substantially perpendicular to one another.

Abstract: An electric machine and vehicular subsystem, apparatus includes a connection disposed within a housing and connecting a high voltage line with the electric machine. A controller controls the coupling of a power source to the high voltage line. A reed switch is positioned within the housing proximate the high voltage line connection. A member is removably mounted on the housing and structured so that removal of the member is necessary to gain access to the high voltage line connection, the member having a magnet. At least one low voltage communication line extends from the reed switch to the controller. Removal of the member from the housing opens the reed switch. Mounting of the member to the housing closes the reed switch. The controller terminates the providing of electric power to the high voltage line when the member is removed from the housing.

Abstract: A high-voltage electric machine has one or more terminals at which wires are to be electrically connected to the machine. The machine's housing includes a cable entrance leading to the terminal(s) through which the wire is inserted. Access holes through the housing enable a technician to reach the terminals (for example, with a tool, such as a screwdriver) to connect each wire to a terminal. In some embodiments, the direction of the access through the hole to the terminal is substantially perpendicular to the direction from which the wire reaches the terminal. A plug may be inserted into each access hole to prevent accidental contact with the terminal(s), such as screw-type or friction-fit plugs.
