APPENDIX B
(3) Number of slots.
(4) Number of coils.
(5) Winding pitch in slots.
(6) Turns in series per coil (TPC), for fractional turn windings, the sequence of TPC for a pole-phase
group shall be shown.
(7) Conductor circular mils or size and form (round or rectangular).
(8) Conductor insulation and Government specification.
(9) Measured resistance between terminals in ohms adjusted to 77 °F (25 °C).
(10) Weight of copper in pounds.
c.
Rotor data including outside diameter, number of bars, bar material, and end ring size and material.
d.
Insulation materials and their dimensions and applicable specification of the following:
(1) Slot cell.
(2) Spacer.
(3) Top wedge.
(4) "U" wedge (where used).
(5) Insulation between phases.
(6) Insulation on coil extensions.
(7) Insulation on coil leads and connections.
(8) Government specification and grade of varnish.
(9) Lead wire size, type, and current carrying capacity.
e.
A detailed working drawing of the shaft
f.
Schematic wiring diagram of motor windings and stator connection diagram.
g. Guaranteed performance including locked-rotor current, torque and power factor; pull-up torque,
breakdown torque, and efficiency and power factor at 2/4, 3/4, and 4/4 load.
h.
Weight of complete motor in pounds.
i. Classification block directly above title block including manufacturer's type and class, frame size, duty
enclosure, speed class, synchronous and full-load r/min, hp, volts, hertz, phases, type of rotor design, class of
insulation, type of mounting, service classification, ambient temperature, and measured full-load amperes. In
addition, the following identification shall be placed below the classification block:
(1) For submarine motors - "SPECIAL QUIET MOTOR DESIGN, MIL-STD-740".
(2) For nonmagnetic motor - "NONMAGNETIC (NM)".
j.
Parts list for repair parts and tools (only) with manufacturer's part numbers.
k.
Phantom view of grease cup, where used, with a note indicating that it is a repair part item only.
l. A connection table of motor leads for two or more speed or dual voltage motors or both. Terminal
markings shall be shown on connection and wiring diagrams.
B.2.3 Drawings for motors with special preload requirements. A drawing shall be provided containing
calculations demonstrating that the preload device functions as intended, as defined by the drawing details of
B.3.l(jj), above, given the preload device tolerances and the tolerances on the parts that restrain them. As a
minimum, the calculations shall include a tolerance stackup analysis calculating the minimum and maximum values
for working length and the minimum and maximum spring force at those lengths.
