Abstract
A coil winding system and process is provided that includes a coil winding fixture and a coil press fixture. The coil winding fixture includes a pair of winding arms each having a set of in-line winding pins. The sets of in-line pins are arranged parallel to one another in one axis, and form an angle to another axis. Magnetic wire is machine wound into the slots between the pins to form coil phases, and, advantageously the individual coils can be wound together to minimize spatial tolerance build-up between phases. Likewise the slots are arranged parallel and adjacent one another to ensure that each winding is parallel to the next to maximize efficiency of the coils. The press fixture includes a forming press and a saddle to form the wound coils into a predetermined shape using heat and pressure applied to the press fixture.
