A stator assembly includes a segmented stator having stator portions. Each stator portion includes a support structure and dovetails, each coupled to the support structure by adjustable elements. The stator portion also includes stator laminations, where each of the laminations has openings to engage with the dovetails. Connectors are provided to connect the stator portions of the segmented stator together.

Segmented stator assembly

A laminated rotor and stator are provided for a dynamoelectric machine. The rotor includes at least one end flange having a plurality of cooling apertures and at least one rotor inner vent lamination having a plurality of cooling apertures. At least one rotor outer vent lamination has a plurality of cooling apertures in communication with a first plurality of radially oriented ventilating slots. The end flange, rotor inner vent lamination and rotor outer vent lamination are configured together into a rotor lamination stack, and the plurality of cooling apertures form a generally axial cooling passage for a flow of a cooling medium.

Ventilated rotor and stator for dynamoelectric machine

An electric machine and a stator assembly include a segmented stator having stator portions. Each stator portion includes end plates arranged axially on opposing sides of the stator portion, support plates arranged interior to the end plates, stator laminations arranged between the support plates, and stabilizing elements coupling the end plates and the support plates together. Each of the stabilizing elements has a dovetail portion coupled to the end plates and to the support plates. Connectors are provided to connect the stator portions of the segmented stator together.

A method for separating electrical runout from mechanical runout includes positioning at least one position probe against a rotating part, positioning at least one proximity probe adjacent the rotating part, and calculating an electrical runout based on measurements obtained from the position probe and the proximity probe.
