Segmented stator assembly
First Claim
1. A stator for an electrodynamic machine having a plurality of segments and a plurality of connectors that are members separate from the segments, each of the separate connectors being releasably attachable to and assemblable with two adjoining segments in a manner such that the adjoining segments are operatively connected sequentially next to one another with the connector in a ring shape to define a core for the stator, each of the segments comprising a plurality of laminations arranged side by side forming a lamination stack with axially opposite sides, the lamination stack having an end cap abutting an axial side of the lamination stack, the end cap having first and second posts extending axially outward from the end cap, at least one of the posts defining a wire path for wire wound around the stack, each of the connectors comprising a bridge portion, the bridge portion having openings dimensioned to receive the posts of the two adjoining segments in a manner such that the connector is removably attachable to and assemblable with the post of the end cap of a segment and the post of the end cap of the adjoining segment of the stator assembly, the connector having an insulator portion projecting from the bridge portion, the insulator portion extending between the adjoining segments with the connector assembled with and removably attached to the adjoining segments.

Abstract
A stator has a plurality of segments connected with connectors to define a core for the stator. Each of the segments comprises a plurality of laminations arranged side by side forming a lamination stack with axially opposite sides. The lamination stack has an end cap abutting an axial side of the lamination stack. The end cap has first and second posts extending axially therefrom. At least one of the posts defines a wire path for wire wound around the stack. Each of the connectors comprises a bridge portion. The bridge portion has openings dimensioned to receive the posts in a manner that the connector is removably attachable to the post of the end cap of a segment and the post of the end cap of an adjacent segment. The connector has an insulator portion projecting from the bridge portion. The insulator portion extends between adjacent segments.
