INSULATING:
A. APPLY EPOXY, INDEX 14, TO POLE BOTTOM, POLE SIDES AND POLE ENDS.
B. INSTALL INSULATION, INDEX 5, ON BOTTOM POLE SIDES. INSTALL INSULATION, INDEX 4,
ON TOP POLE SIDES. INSTALL INSULATION, INDEX 6, ON POLE ENDS. INSTALL INSULATION,
INDEX 7, ON POLE SIDES.
3. WINDING:
A. ADJUST WIRE TENSION TO 70 LBS.
B. APPLY SLEEVE, INDEX 13, TO START LEAD OF EACH COIL.
c . WIND THE FIRST LAYER WITH 10 TURNS TO FILL THE WINDING SPACE. FORM THE COIL SIDES
WITH A FIBRE BLOCK TO OBTAIN FLAT AND TIGHT WINDING. DO NOT FORM COIL ENDS. APPLY
EPOXY, INDEX 14.
D. CONTINUE WINDING COMPLETE COIL AS DESCRIBED IN WINDING NOTE 3B, MAKING SURE TO
APPLY EPOXY, INDEX 14, TO COVER ALL TURNS AND TO FILL ALL VOIDS THROUGH THE ENTIRE
WINDING. THIS WILL REQUIRE BRUSHING EPOXY ON ALL LAYERS. FORM COIL SIDES WHILE
WINDING TO PRODUCE FLAT SIDES. WIND EACH COIL WITH 160 TURNS, 10 TURNS PER LAYER,
4 COILS.
E. APPLY SLEEVING, INDEX 13, TO ENDING LEAD OF EACH COIL. SELECT START LEAD 0F
ARBITRARY COIL AND CONNECT COILS IN SERIES, HOMOGENOUS WELD, AND USE PARALLEL
SPLICE, INDEX 16.
F. CONNECT LEADS, INDEX 12, TO REMAINING TWO LEADS, SOLDER
USING SOLDER, INDEX 17.

BAKE COMPLETED ROTOR FOR A MIN. OF 24 HOURS AT 325" F to 35 F.
5. HEAT HUB, INDEX 3, TO 400" F THEN SHRINK FIT ON SHAFT, INDEX 1, TO SHOULDER.
6. STAMP PART NUMBER AS SHOWN BELOW PER MIL-STD-130, 0.12 MIN HEIGT. USING WHITE
ENAMEL PAINT.
