It will be placed so asto bridge every other tooth in the stator core inone continuous length by stringing it through oneslot, crossing over at the end of the slot to thenext slot, back through and on to the third slot,continuing until it is back at the starting point.The starting and finish ends shall be securely tiedtogether. This bridge is to restrain the end turn tiecord.(e) Coils shall be inserted in slots so thatoverhanging ends are equally spaced. Wirebundles at entrance to slot should be brought outas straight and compactly as possible to reduceside pull on overhanging slot tube ends.(f) Care should be taken to see that wire insulation isnot scratched or otherwise damaged. Coil wiresshould not be linked or crossed in the slots. Toolsinserted into slots to adjust position of wires orseparators should be free from burrs or sharpedges to prevent damage to wire or slotinsulation. If it is necessary to use a mallet whentamping down wires or separators in slots, tap theslot tools lightly. Heavy pounding will ruin theinsulation.(g) After bottom coil sides are in the slots, theseparators are wedges in place with theiroverhanging ends equally spaced. These endsshould project approximately 1-1/2 inches (38mm) from edge of core. The separators should fittightly enough to hold the coils down in the slots.(h) Phase insulating strips are placed in the end turnsto insulate between the coil groups on both endsof the winding. These strips should be placedso that the back edge reaches the ends of thewedges approximately 1/2 inch (13 mm) fromcore. The strips will then overlap the ends of theseparators. After coil ends are properly shaped,trim phase insulating strips all around so that 1/16to 1/4 inch (0.2 to 0.6 mm) of edge projectsbeyond edge of wires. Phase insulating stripsmay extend 1/2 inch (13 mm) beyond wire on coilouter diameters.(i) Top sticks shall be carefully inserted so that slottubes and wire are not damaged. The overhanging ends should be equal and they should belevel. Top sticks which are broken or split duringinsertion should be replaced.(j) Connections shall be twisted together and brazedusing brazing alloy.
