Embodiments of the present invention are directed to an apparatus for inserting an undulated coil assembly in a plurality of slots of a hollow core of a stator of a dynamoelectric machine. In some embodiments, the hollow core includes a hollow core central rotation axis, the undulated coil assembly is formed by a plurality of undulated coils, and each of the plurality of undulated coils including adjacent superimposed linear portions (LI). At least three of the plurality of undulated coils extend parallel to each other and a plurality of turn portions (T) connecting the adjacent linear portions (LI) thereof. The apparatus includes, inter alia, a support member, a first guide device aligned with respect to each of the end faces and the plurality of slots of the hollow core, a passage associated with the first guide device which includes at least one guide surface, a feeder that feeds the first coil portion, and moving means for relatively moving the hollow core with respect to the first guide device to position the plurality of slots of the hollow core for receiving the superimposed linear portions (LI).

Apparatus for inserting an undulated coil assembly in slots of a core of a stator of a dynamoelectric machine

Embodiments of the currently claimed disclosure are directed to methods for inserting an undulated coil assembly in the slots of a hollow core of a dynamoelectric machine. In some embodiments, the method can include positioning at least a first coil portion of the coil assembly around a support member, aligning a guide device with respect to end faces and the slots of the core, feeding the first coil portion from the drum support member along the guide device to insert adjacent superimposed linear portions (LI) of the coil assembly in the slots, engaging the superimposed linear portions (LI) along at least one guide surface during the feeding, and relatively moving the core with respect to the guide assembly device to position the slots for receiving the superimposed linear portions (LI).
