Abstract
A method of making a wound field for a brushless direct current motor, direct current generator, alternating current motor or alternating current generator, includes providing a base mold having an engagement face with at least one movable end turn form. A number of distinct phases is determined and at least one strand of conductive material is wound around at least one movable end turn forming tool per distinct phase. One conductive coil is created from each strand of conductive material for each distinct phase. Each conductive coil is formed into a configuration that indicates the number of poles required. Each conductive coil is then placed onto an insertion instrument. The insertion instrument and each conductive coil are inserted into a stator core. The insertion instrument is removed from the stator core, and the stator core is installed into one of the aforementioned motors or generators.
