A bar wound stator assembly includes a connection module attached to a stator core at a weld end of the stator assembly. The connection module provides all required electrical connections to connect shaped plurality of hairpin bar connectors of the stator assembly within a first pole pair of a winding set of conductors. All of the hairpin bar conductors include an identical span. The connection module completes each phase of the winding set, to connect each phase of the winding set to define a connection configuration, e.g., a wye or a delta connection configuration, and to connect the stator assembly to all external connections.

A support ring for a rotor having a core and a plurality of windings. The support ring includes an annular base, a plurality of fingers, and a plurality of loaded edges. The plurality of fingers extend radially outward from the annular base, and each generally corresponds to one of the windings. The plurality of loaded edges extend axially from the fingers and are disposed radially outward of the windings.

An interior permanent magnet machine includes a rotor configured to magnetically interact with a stator. First and second dividers are integrally formed within the rotor and configured to create a first layer of three respective first segments. Each of the respective first segments may be substantially arc-shaped. A plurality of first magnets may be positioned in the first layer. The first magnets may be substantially arc-shaped and defined around an arc center. A third and a fourth divider may be integrally formed within the rotor and configured to create a second layer of three respective second segments. The placement of dividers or structural webs provides for increased rotational speed and reduced rotational stress compared to an undivided arc-shaped magnet configuration.

An electric machine having a stator body and a machine housing is provided. The stator body includes a stator ring of generally annular shape and a plurality of stator teeth projecting radially inward. A first bolt hole is defined in either the stator ring or machine housing, and a first receptacle is defined in the other and is coaxial with the first bolt hole. A second bolt hole is defined in either the stator ring or machine housing, and a second receptacle is defined in the other and is coaxial with the second bolt hole. A first counter bore is coaxial with the first receptacle. A first hollow dowel is mated to the first counter bore and the first bolt hole, and defines a first dowel hole, which is coaxial with the first counter bore and the first bolt hole.

A bar-wound stator includes a plurality of bar-type conductors disposed within the plurality of slots, wherein, within each slot, at least one of the bar-type conductors has an orientation that differs from the remaining bar-type conductors within that slot by a predetermined angle. For example, conductors with rectangular cross-sections can be inserted such that the conductors closest to the inner surface of the stator are rotated ninety degrees with respect to the remaining conductors.
