Abstract
A winding insertion device for axially inserting the windings of a dynamoelectric machine is provided with a pair of blade holders axially aligned with respect to one another. A first set of blades is attached to one of the blade holders, and a second set of blades is attached to the second blade holder. Individual ones of the first and second blade sets are arranged alternately with respect to one another, and the blades define an annular array when viewed in plan. Means are provided for moving the first and second blade holders relative to each other in a reciprocal movement pattern during winding insertion, with consequent movement of the respective blade sets. Because of the relative blade holder movement, the actual distance of movement required for individual ones of the first and second blade sets is small. Consequently, the insertion device is compatible with a wide range of stator assembly stack heights constructed from laminations having a variety of slot configurations.
