ABSTRACT:
In a dynamoelectric machine having a rotating field and a stationary stator core, electrical conductors are contained within axially-extending radial slots which are part of the stator core construction. These electrical conductors are subject to electromagnetic forces and thermal cycling effects which, over a period of time, tend to cause the electrical conductors to become loose within their slots. A system of wedges is used to retain these electrical conductors in place and in particular a dovetail wedge is used in combination with a mating surface in a stator slot.
