BUSS BAR ASSEMBLY HAVING AXIALLY STACKED BUSS BAR PLATES

摘要

A buss bar assembly (20) for a multiphase electrical machine, including a substantially annular dielectric housing (22) having a central axis (54), a plurality of dielectric phase bar mounting members (40) located within the housing (22), and a plurality of electrically conductive phase bars (28). The phase bars (28) are disposed in the housing (22) and substantially surround the central axis (54). Each phase bar (28) has opposing, substantially planar axial sides and is in engagement with at least one phase bar mounting member (40). An axial side of each phase bar (28) is in superposition with an axial side of another phase bar (28) whereby the plurality of phase bars (28) are axially stacked along the central axis (54). The phase bars (28) have mutually spaced positions relative to each other in directions along the central axis (54), these positions defined by the phase bar mounting members (40) whereby the phase bars (28) are electrically isolated from each other within the housing (22).
