Abstract

An apparatus and method for forming at least one end turn and one slot segment of a coil for a stator of a dynamoelectric machine includes the utilization of a plurality of forming dies. Each forming die includes two lateral surfaces extending from a base and an end turn surface disposed substantially between and connecting the two lateral surfaces. Each forming die is disposed and pivotable into an arrangement where at least one lateral surface of a first forming die is substantially adjacent and parallel to at least one lateral surface of a second forming die, a slot segment thereby formable between lateral surfaces of adjacent forming dies and an end turn is at least partially formable between an end turn surface and a base of adjacent forming dies.

Claims (10)

1. A method of forming at least one end turn and at least one slot segment in a conductor for a stator of a dynamoelectric machine comprising:

locating a conductor between at least a first forming die and a second forming die of a plurality of forming dies, the first forming die and second forming die pivotably disposed, each forming die of the plurality of forming dies including two lateral surfaces extending from a base and an end turn surface disposed substantially between and connecting the two lateral surfaces;

pivoting the first forming die toward the conductor;

capturing at least a portion of the conductor between the first forming die and the second forming die;

pivoting the second forming die until at least a first lateral surface of the first forming die is substantially parallel to and adjacent to a second lateral surface of the second forming die;

forming a slot segment between the first lateral surface and the second lateral surface; and

forcing the conductor against the second forming die, thus creating the desired end turn shape in the conductor between the end turn surface of the first forming die and the base of the second forming die.

2. The method of claim 1 wherein the conductor is captured between an end turn surface of the first die and a base turn surface of the second die.

3. The method of claim 1 wherein the end turn surface is gable-shaped.

4. The method of claim 1 wherein the first die and the second die are rotably mounted to a plate.
