APPENDIX B
e. 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 and calculated value of safe locked-rotor
time.
f.
Stator inside and outside diameters and core length.
g. Rotor outside diameter, number of bars, and bar material. Indicate reference line and dimension for
locating rotor axially on shaft in connection with replacement of shaft or rotor.
h.
Size of end ring and end ring material.
i.
Winding data of stator, including:
(1) Number of poles.
(2) Type of connection.
(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.
(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.
j.
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 and current carrying capacity, and lead wire markers.
k.
Slot sections showing dimensions of sections and details of slot wedges, slot armor, coil spacers, and slot
tubes.
1. Sketches showing in detail how field coils, where used, are assembled, insulated and supported on the pole
pieces, and method of preventing excessive relative motion between the various conductors and windings when
subjected to high-impact shock.
m. Where seals are used, a sketch showing construction of seal and method used to secure seal in its housing
and shaft to prevent axial or rotational movement.
n. Data from the first article inspection, verified and attested to by the Government Quality Assurance
Representative, shall be used to comply with the following test data requirements. For multispeed motors, the test
data shall be included for each definite speed:
(1) Table of heat run data containing the following:
(a) The hp load, amperes and loading duration.
(b) Temperature measurements, by thermocouple, of the ambient air and the motor parts listed in table
XIV. Measurements, in degrees centigrade, shall be shown for operation 1 hour before shutdown (in case of short-
time duty motors this column need not be completed) final while running (prior to shutdown), and after shutdown.
