Contract or order number
3.5.1.33.2 Frame and rotor. The manufacturer's serial number shall be stamped or otherwise permanently
marked in the solid metal of the frame underneath (covered by) the main identification plate. The part number, or
other information sufficient to completely identify one rotor, shall be stamped or otherwise permanently marked on
the shaft or rotor core. Marking of armatures and field coils shall identify the manufacturer and the style and type of
motor.
3.5.1.33.3 Sealed insulation system information plates. Motors with sealed insulation shall have the following
information plates:
a. The plate shall list the name of the activity performing the sealed insulation system. The plate shall also
contain the statement: "Stator windings insulated to provide a sealed insulation system. Caution: When stripping,
oven temperature not to exceed 370 °C, measured on core" (see figure 5).
3.5.1.34 Interchangeability. Bearing caps, bearing cap fasteners, end bells, end bell fasteners, air baffles, parts
that affect lubrication, and repair parts that are physically interchangeable shall be either functionally
interchangeable or shall be permanently marked "DE" (drive end) or "ODE" (opposite drive end) (see 6.6.1), as
appropriate. Permanent marking shall be clearly legible and shall be accomplished by metal stamping or a process
that will produce not less than an equivalent level of clarity and permanence. The above parts that are physically
reversible shall be functionally reversible.
3.5.1.35 Direction of rotation. Unless otherwise specified (see 6.2), motors shall be inherently reversible
(constructed for operation in either direction). Inherently nonreversible motors and motors driving nonreversible
auxiliaries shall be equipped with permanently mounted identification plates as specified (see 3.5.1.33) to indicate
the direction of rotation when viewed from the end of the motor opposite the normal drive shaft (see figure 5).
3.5.1.36 Provision for measuring speed (explosionproof and explosionproof, fan-cooled motors excluded). In
motors having a single shaft extension, provision shall be made for the measurement of speed with a hand type
tachometer. This shall be accomplished on the opposite drive end either by extending the shaft flush with (or
slightly beyond) the outer face of the bearing housing, or by providing a hole and a plug in the outer end of the
bearing housing. When a hole and plug are provided, the hole shall be threaded and not smaller than 9/16-inch
diameter, and the plug shall not be able to interfere with the end of the shaft. A lathe center or other suitable hole
shall be provided in the end of the shaft for the insertion of the tachometer tip. For fan-cooled motors a hole not
smaller than 9/16-inch diameter shall be provided in the fan guard for access to the end of the shaft. The hole shall be
securely covered and shall be in accordance with MIL-STD-108.
