Abstract
Relatively large coils or windings are positioned in relatively lengthy stator cores with the aid of a coil placing machine by placing coils over certain finger elements of the machine, revolving the set of finger elements and corresponding insulating wedge guides and placing further coils over other of the finger elements. Thereafter, a dynamoelectric machine stator core is positioned in axial alignment with the finger elements with one end face thereof engaging the wedge guide ends and with the finger element free ends just entering the bore of the stator core. A stripper and the plurality of finger elements are moved together along the bore of the core to lead side turn portions of the coils into and along respective core slots whereupon movement of at least some of the finger elements is halted while movement of at least the stripper continues to complete placement of the coils. The process may be implemented by providing a stator support cradle which is movable along an elongated machine bed and supports a fixed generally cylindrical tooling enclosure in general axial alignment with the direction of cradle movement. Coil placer tooling is positioned within the enclosure extending somewhat therefrom toward the cradle to receive the coils and thereafter be extended further from the cradle under the control of a first fixed fluid actuated cylinder. A second fluid actuated cylinder movable with the tooling may be employed to impart the additional movement of a portion only of the tooling to complete the insertion process. An accessory for and method of modifying such a machine so as to adapt it to cores of different axial lengths is also disclosed.
