Abstract
The need for specialized tooling which was previously required to accurately place the first layer of turns in a precision winding of a rotor having an even number of layers of turns is eliminated by providing self-fixturing wire-guiding features in corners of slots in the rotor which receive the winding, thereby facilitating the manufacture or repair of precision-wound rotors. In some exemplary embodiments, the self-fixturing wire-guiding features are provided by configuring the corners of the slots to include a chamfer or shoulder. In other exemplary embodiments, a specially shaped slot liner inserted into the slots includes a corner spacer which provides the self-fixturing wire-guiding feature.
