Abstract:
A mandrel (20) for forming field windings for a slotless stator includes a spindle (22) and a winding guide (24) substantially enclosing the spindle (22) circumferentially. The spindle (22) is rotatable relative to the winding guide (24) about a longitudinal axis (28), and the spindle has a plurality of outwardly extending guide pins (30) circumferentially arrayed in longitudinally spaced rings. The mandrel (20) also includes a winding guide (24) which surrounds the spindle (22) and guides the winding onto the pins (30) and maintains the windings on the pins until the windings can be fixed in place. The pins (30) are retractable for removing the windings from the mandrel (20) completely formed and ready to be placed in a motor.
