MOTORS
Environmental
Options
Condensation Drain Holes
NORD motors can be equipped with condensation
drain holes. These drain holes are placed in the
motor endbells at the lowest possible point. The
drain holes are closed at the factory with plastic snap
in plugs. They allow for condensation accumula-
tion in the motor to drain after the closing plugs are
removed.
The motor drain holes can be provided by NORD
either open (KBO) or sealed with a closing plug (KB).
Condensation Drain Holes,
Plugged (KB)
KB drain holes are plugged for shipment. In order for
the holes to effectively drain moisture, the plugs must
be removed before using the motor.
Condensation Drain Holes,
Open (KBO)
KBO drain holes are shipped open (not plugged).
IP66 Enclosure Protection
NORD motors can be provided with an IP66 enclosure
protection. IP66 protection is suitable for wet, high-
pressure wash down and extremely dusty environ-
ments, and includes all requirements included in IP65
enclosure protection.
Terminal Box Sealed with Resin (KKV)
Terminal boxes can be sealed with a fl exible, electrical-
ly safe resin to ensure that contaminants, water, and
moisture cannot pass through the terminal box into
the stator body. This option is helpful in extremely
dusty, wet and humid environments. Another envi-
ronment where this option is helpful is in installations
that have frequent large temperature swings where
condensation may form.
Additional Insulation (AICM)
NORD can provide additional insulation inside the
motor to provide additional electrical protection in
extremely wet or corrosive environments. An elec-
trically safe insulating material is coated internally in
the stator windings and on the rotor body
Epoxy Dipped Windings (EP)
In extremely wet environments, the motor windings
are dipped in epoxy for improved moisture protection.
The motor can also be treated with the standard NORD
Severe Duty + (NSD+) package for an even higher
degree of protection.
Canopy Drip Cover (RD)
For wet or dirty installations where the
fan end of the motor is mounted up, thus
allowing water or debris to fall into the
motor’s fan guard, NORD offers a canopy
drip cover to block this falling water or
debris.
Double Fan Cover (RDD)
For wet or dirty installations where the
fan end of the motor is mounted up, the
NORD Double Fan Cover provides protec-
tion against falling or wind blown water,
snow, dirt or debris from entering the back
of the motor.
