The present invention facilitates the placement of laminationsonto keybarsof stator generators frames. Laminations need to be tightly fit onto keybars, however, the same need for tightness makes stacking laminations onto keybars particularly onerous. This is magnified when donuts, which are preassembled groups of laminations, are attempted to be stacked onto the keybars. The present invention provides for enlarged groovesthat more easily accept the keybars. This makes stacking laminations, both individually and in donuts, much easier. The laminations are then held in position by the insertion of a wedge. The wedge may be placed to disperse forcestransferred to the laminations in a circumferential manner

A dynamoelectric machine includes a rotor and a stator surrounding the rotor. The stator includes a plurality of windings arranged in a main portion adjacent the rotor and terminating in a plurality of inner and outer end windings extending outwardly from the main portion. An end winding support assembly includes at least one support ring for the plurality of end windings and a respective adjustable bias member between the at least one support ring and each adjacent end winding to provide an adjustable separation bias between the at least one support ring and each adjacent end winding.

An apparatus useful in clamping stator coil windings of a turbine generator includes a retaining platform for extending across a pair of the coil windings positioned in a spaced relation. The retaining platform includes a bore extending therethrough. A connecting insert member is slidably carried within the bore and has a through-hole with separable mating segments for admitting a rod into the through-hole. An elongated rod passes through the throughhole of the connecting insert member, which rod includes a bulbous shaped end dimensioned for passing through the bore of the retaining platform but cannot pass through the through-hole of the connecting insert member. Thus providing tension in the elongated rod biases the platform against the pair of coil windings.

A dynamoelectric machine comprising a stator core with slots therein and top and bottom coils contained in each of the slots and extend from the end of the stator core is provided. A radial clamp for securing a pair of adjacent top coils together with a pair of bottom coils is provided. The radial clamp comprises a support block radially outside the pair of top coils. The support block has an aperture that is substantially radially lined in relation to the axis of the machine. A retaining platform is coupled proximate the bottom coils. The retaining platform defines a bore. A connecting insert member that is adapted to be adjustably mounted within the retaining platform bore is provided. The connecting insert member further defines an aperture. A traverse pin is mounted proximate the support block. A radially extending banding material having a first end and a second end which has a head portion is provided. The first end of the banding material is formed around the pin with the banding material running through the first support block aperture and with the head portion received within the connecting insert member aperture such that the connecting member can be adjusted to adjust the length of the banding material.
