A stator for a multiphase electric motor includes a plurality of laminates stacked to form a cylindrical stator core having a plurality of longitudinal slots; a plurality of electrical conductors grouped into a plurality of discrete electrical circuits, each of the plurality of the electrical conductors forming a plurality of coils in the slots spaced about the stator core, and each of the coils having a pair of leads; a plurality of bus cables, each of the plurality of bus cables having a mechanical connection to the pluralities of coils at ends of the slots; and wherein one of the leads from each of the coils is electrically connected to one of the plurality of bus cables.

Stator for a multiphase electric motor and method of making

A repaired rotor of a multi-phase electric motor includes a plurality of annular laminations stacked to form a cylindrical core about a central axis, each of the laminations having notches aligned to form axially extending slots about a periphery of the core; a plurality of electrical conductors extending through the slots; a pair of conductive end rings, each attached to a different end of the cylindrical core and electrically connected to the plurality of electrical conductors; and an outer end ring abutting and electrically connected to one of the pair of conductive end rings and electrically connected to adjacent ends of the plurality of electrical conductors, the outer end ring providing an uninterrupted electrically conductive path connecting the plurality of electrical conductors.
