Abstract
A main field coil for use in a dynamoelectric machine has a support having a predetermined geometry and a solid strand electrical wire with a circular cross section wound about the support. Coilhead (end turn) air vents of predetermined width are interspaced in the wound electrical wire. A structurally rigid removable pin has a grooved portion for receiving the wire and holding it as the air vents are formed, the pin being located at least partially in the air vents. The removable pin is removed from the air vents after the electrical wire is wound about the support.
