Abstract A dynamo-electric machine provided with a retention mechanism for conductors disposed in a core slot is disclosed, wherein the mechanism comprises at least one composite wedge arrangement consisting of a first wedge having its wedge-shaped surface extending longitudinally of the slot, a second wedge similar to the first and also having its wedge-shaped surface extending longitudinally of the slot but disposed with its direction of taper opposed to that of the first wedge, there being further provided a spring member cooperating with the composite wedge arrangement, the spring member extending longitudinally of the slot and its deformation being dependent upon the relative longitudinal displacement in the slot of the first and second wedges.
A dynamo-electric machine provided with retention means for conductors disposed in a core slot, comprising in combination at least one composite wedge arrangement consisting of a first tapered wedge having a wedge-shaped surface thereof extending longitudinally of the slot, and a second tapered wedge similar to said first wedge and having a wedge-shaped surface thereof extending longitudinally of the slot but disposed with its direction of taper opposed to that of said first wedge, a spring member cooperating with said composite wedge arrangement, said spring member extending longitudinally of the slot and having its deformation dependent upon the relative longitudinal displacement in the slot of said first and second wedges, and wherein said composite wedge and said spring member are disposed in a U-section closure member running along the mouth of the slot.
