High voltage generator stator with radially inserted cable windings and assembly method
First Claim
1. A stator for a dynamo electrical machine comprising:
- a circular array of stator sidewalls extending radially outward from a rotor opening, stator teeth with key segments alternating along the radial length of said sidewalls, and stator slots defined between opposite sidewalls;
separator bars in said stator slots and extending longitudinally along said stator, said separator bars engaged with the opposite sidewalls of the teeth, wherein a plurality of separator bars are stacked in a stator slot, and cable windings seated between adjacent separator bars in the stator slots.

Abstract
A stator for a high voltage generator has cable windings that are radially inserted into the stator slots. The stator is assembled as the cable windings are laid into the stator slots. The stator slots are left wide open to allow the cable windings and separator bars to be inserted in the slot as the stator is assembled. The open slots have sidewalls that are defined by stator teeth, which extend radially out from a rotor jig in the stator. As each coil section is laid in a slot, a separator bar is inserted over the coil so that another coil section can be laid into the stator. The coils are stacked in a slot and sandwiched between separator bars also in the slot. The separator bar is keyed to the sidewalls of the teeth to provide structural support for the cable windings.
