<p>Apparatus for winding single-layer, precision wound dynamoelectric machine field coils and for inserting such coils in an internally-slotted core member includes a coil form having portions shaped to form a coil with two angled sections joined to end sections. The coil form has a distal end with a recess therein which communicates with the angled section-forming portions. Insertion apparatus is provided having a cylindrical array of elongated, parallel blades defining gaps radially aligned with the centerline of the array. The diameter of the wire from which the coil is wound approaches the width of the gaps. The array has a first position in which the distal ends of a group of adjacent blades extend into the coil form recess generally at right angles to the coil with the two gaps at the sides of the group exposed to the angled section-shaping portions so that a coil wound on the coil form may be transferred to the array with the angled sections extending through the two gaps and one end section disposed within the array. The array has a second position with the distal ends of the blades extending into the bore of the core and engaging teeth thereof, and with the two gaps communicating with two winding slots, the two gaps defining a first angle therebetween. The angled sectionshaping portions of the coil form define a second angle therebetween slightly smaller than the first angle and having a center spaced outwardly from the centerline of the array on the side thereof remote from the one end section in the first position of the array. The facing sides of each pair of adjacent blades which define the gaps diverge toward the center of the array 50 that the coil on the blades may be pivoted to an insertion position defining an acute angle with the blades with the two angled sections of the coil defining a third angle therebetween slightly larger than the first angle and the projected centerlines of the angled sections meeting at a point spaced inwardly from the centerline of the array on the side thereof toward the one end section in the insertion position of the coil.</p> |
