APPENDIX A
(10) Bearing and bearing seats are free from dirt, sand, metal particles, corrosion, or other foreign
material.
(11) Lamination size and stacking are as shown on the approved drawings.
(12) Slot or ground insulation are as shown on the approved drawings.
(13) Slot or ground insulation extends beyond stacking as shown on the approved drawings.
(14) Wire size and type is as shown on the approved drawings. There are no substitutions.
(15) Wound coils (including preformed) have dimensions and number of turns as shown on the approved
drawings.
(16) Undue force is not required to insert slot wedge in place, and insulation is not damaged or pushed out
of place by the wedge.
(17) Slot wedges are of material and size as shown on the approved drawings. Length of wedge exceeds
length of slot as shown on the approved drawings.
(18) Coils are not loose after the wedge is in place.
(19) The wedge size is proper for the size and shape of the slot, and there is no possibility that the wedge
will cock in the slot and slip out.
(20) Coil connections are insulated as shown on the drawings.
(21) Coil support and phase insulation is as shown on the approved drawings. Phase insulation is inserted
between the phase coils and is shaped to fit coil configurations.
(22) Coil extensions are insulated and secured as shown on the approved drawings.
(23) Insulation materials are as shown on the approved drawings.
(24) Insulation is cleaned off unless self-fluxing wire is used, and coil wire ends are tinned before making
soldered connections.
(25) Lead wires are of the type and size shown on the approved drawings.
(26) Windings are mechanically secured as shown on the approved drawings.
(27) Completed winding assembly, including winding and pole, has been given a minimum of two
varnish treatments with an approved clear baking varnish when preformed coils are used and has been given one
varnish treatment prior to insertion in the slots or on the poles. When preformed coils are not used, the complete
assembly has been given at least three varnish treatments.
(28) Type of varnish, treating and baking time cycle, and baking temperatures are shown on the approved
drawings.
(29) The treated windings and coils are clean, smooth, and glossy with good bonding and filling. Varnish
seals are complete and show no signs of cracks or breaks. The completed winding has no air bubbles, air pockets,
voids, or dry spots on the surface and is not soft or sticky.
(30) There is no sign of excessive varnish buildup on one side of the winding assembly and lack of
varnish buildup on other side. The thickness of the varnish on the winding assembly is uniform over the entire
surface of the windings.
(31) Lead wires are insulated from ground and secured to prevent them from moving due to centrifugal
force. Length and arrangement of wires permit ready repair; there is no aimless wiring resulting in "rats' nests."
Wiring is as shown on the approved drawings.
(32) No glyptal or nonapproved type of varnish or paint has been put on any of the rotating elements.
(33) Coils or windings have not been nicked or damaged during handling and processing.
(34) Completed rotating elements are dynamically balanced. The type of balance weights and method of
securing are as shown on the approved drawings. Rotating elements have been secured to prevent loosening in
service. Balance weights are not attached in the air stream to the fan.
c. Items examined during winding and assembly of stationary elements. Examination during winding and
assembly of stationary elements shall be conducted to determine whether items conform to the following:
