tubes should be adjusted so that height of sides is
equal.
(d)
After the slot tubes have been inserted, insulating
tape shall be placed into the stator to form a
bridge between slot tubes. It will be placed so as
to bridge every other tooth in the stator core in
one continuous length by stringing it through one
slot, crossing over at the end of the slot to the
next 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 tied
together. This bridge is to restrain the end turn tie
cord.
(e)
Coils shall be inserted in slots so that
overhanging ends are equally spaced. Wire
bundles at entrance to slot should be brought out
as straight and compactly as possible to reduce
side pull on overhanging slot tube ends.
(f)
Care should be taken to see that wire insulation is
not scratched or otherwise damaged. Coil wires
should not be linked or crossed in the slots. Tools
inserted into slots to adjust position of wires or
separators should be free from burrs or sharp
edges to prevent damage to wire or slot
insulation. If it is necessary to use a mallet when
tamping down wires or separators in slots, tap the
slot tools lightly. Heavy pounding will ruin the
insulation.
(g)
After bottom coil sides are in the slots, the
separators are wedges in place with their
overhanging ends equally spaced. These ends
should project approximately 1-1/2 inches (38
mm) from edge of core. The separators should fit
tightly enough to hold the coils down in the slots.
(h)
Phase insulating strips are placed in the end turns
to insulate between the coil groups on both ends
of the
winding. These strips should be placed
so that the back edge reaches the ends of the
wedges approximately 1/2 inch (13 mm) from
core. The strips will then overlap the ends of the
separators. After coil ends are properly shaped,
trim phase insulating strips all around so that 1/16
to 1/4 inch (0.2 to 0.6 mm) of edge projects
beyond edge of wires. Phase insulating strips
may extend 1/2 inch (13 mm) beyond wire on coil
outer diameters.
(i)
Top sticks shall be carefully inserted so that slot
tubes and wire are not damaged. The over
hanging ends should be equal and they should be
level. Top sticks which are broken or split during
insertion should be replaced.
(j)
Connections shall be twisted together and brazed
using brazing alloy. The distance from the first
twist to the film coating on
