3.5.1.29 Temperature limitations. Motor temperature limitations shall be as specified in 3.6.11.
3.5.1.30 Conventional insulation. Conventional insulation, where applicable (see 3.5.2.1 and 3.5.2.2), shall be
in accordance with MIL-E-917.
3.5.1.30.1 Insulation class. Insulation class shall be F, H, or N in accordance with MIL-E-917 (see 6.2).
Where ambient temperatures of 104 °F or 122 °F (40 °C or 50 °C) are specified, the insulation shall be Class F.
3.5.1.30.2 Slot insulation and varnishing. Slot cell shall be folded under the slot wedge if flat wedge is used, or
inserted inside the slot wedge if formed (curved) wedge is used. The wedge shall extend the full length of the slot
and extend past the iron a minimum of ¼ inch. The wedge shall be positioned so as to completely cover the slot
cell. For motors in frame sizes 215 or smaller, the flat or curved wedges may be inserted inside the slot cell, and in
such cases, the following conditions shall apply:
a. The slot wedge shall extend the full length of the slot cell and completely cover the windings and close the
slot necks.
b.
The wound stator shall be given a minimum of two varnish dips and bakes.
3.5.1.31 Sealed insulation system. The sealed insulation system (see 6.6.24) shall be applied to random wound
and form wound motors by manufacturers qualified by NAVSEA in accordance with MIL-STD-2037 (see 4.2.1).
For applicability of sealed insulation to particular motor services, see 3.5.2.1 and 3.5.2.2. In addition, motors with
sealed insulation systems shall meet the following requirements:
a. Insulation shall be Class F. The insulating materials used in motors with a sealed insulation system need
not meet the minimum material requirements of 3.5.2.1.1.
The terminal box shall be watertight.
b.
c. Motors furnished with sealed insulation systems shall be constructed so that they can be repaired (rewound)
using sealed insulating materials and processes or rewound using conventional rewinding materials and methods.
d. Insulation resistance, corrected to 77 °F (25 °C), shall be not less than 1000 megohms, dry, and 100
megohms, submerged (see 4.6.19).
3.5.1.33 Identification. Motors shall have identification plates (and information plates where required) which
shall be attached to the part of the machinery or equipment which will not ordinarily be replaced during its normal
service life. These plates shall be located where they can be read at all times without danger to personnel.
Identification plates and information plates shall be made of brass, nickel-copper-alloy, or corrosion-resistant steel
in accordance with MIL-DTL-15024 and MIL-P-15024/5.
3.5.1.33.1 Identification plate markings. Unless otherwise specified (see 6.2), the minimum information to be
on identification plates for motors shall include the following items:
a.
Manufacturer's information as follows:
(1) Name
(2) Identification symbols
(3) Serial number
(4) Manufacturer's drawing number, including revision symbol
(5) Date of manufacture
b. Salient design characteristics (this information shall agree with information shown in the classification
block of manufacturer's drawing):
(1) hp (or torque rating)
(2) Design
(3) Voltage
